快速分段 LSP 配置

分步过程

下面的示例要求您在各个配置层级中进行导航。有关导航 CLI 的信息，请参阅 CLI 用户指南中的在配置模式下使用 CLI 编辑器。

要配置设备 R0：

1. 将网络服务模式配置为增强型 IP。增强型 IP 将路由器的网络服务设置为增强型 Internet 协议，并使用增强模式功能。

   user@R0#set chassis network-services enhanced-ip
   

   配置 enhanced-ip 语句并提交配置后，将显示以下警告消息，提示您重新启动路由器：

   content_copy zoom_out_map

   'chassis'
   WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior.
   commit complete

   重新启动将显示路由器上的 FPC。

2. 配置接口以启用 IP、MPLS 和 ISO 传输。

   content_copy zoom_out_map

   [edit]
   user@R0#set interfaces ge-0/0/0 description To_R1_1
   user@R0#set interfaces ge-0/0/0 unit 0 family inet address 192.168.1.1/24
   user@R0#set interfaces ge-0/0/0 unit 0 family iso
   user@R0#set interfaces ge-0/0/0 unit 0 family mpls maximum-labels 8
   user@R0#set interfaces ge-0/0/2 description To_R4_1
   user@R0#set interfaces ge-0/0/2 unit 0 family inet address 192.168.2.1/24
   user@R0#set interfaces ge-0/0/2 unit 0 family iso
   user@R0#set interfaces ge-0/0/2 unit 0 family mpls maximum-labels 8
   

3. 配置环路接口以启用隧道端点和服务端点。

   content_copy zoom_out_map

   [edit]
   user@R0#set interfaces lo0 unit 0 family inet address 10.100.100.100/32
   user@R0#set interfaces lo0 unit 0 family inet address 10.100.100.101/32
   user@R0#set interfaces lo0 unit 0 family iso address 49.0001.000a.0a0a.0a00
   

4. 配置路由选项以标识域中的路由器。

   content_copy zoom_out_map

   [edit]
   user@R0#set routing-options router-id 10.100.100.100
   user@R0#set routing-options autonomous-system 65100
   user@R0#set routing-options static route 10.7.7.71/32 next-hop 10.7.7.7
   user@R0#set routing-options static route 10.7.7.71/32 resolve
   

5. 定义导入和导出策略。例如，配置将 EPE TE 链路从本地 TE 数据库 lsdist.0 导出到的策略以及要从 lsdist.0 中导入到本地 TE 数据库的策略。您可以配置策略以将 BGP 路由播发至对等方。

   content_copy zoom_out_map

   [edit]
   user@R0#set policy-options policy-statement nlri2bgp_epe term 1 from family traffic-engineering
   user@R0#set policy-options policy-statement nlri2bgp_epe term 1 from protocol bgp-ls-epe
   user@R0#set policy-options policy-statement nlri2bgp_epe term 1 then next-hop self
   user@R0#set policy-options policy-statement nlri2bgp_epe term 1 then accept
   user@R0#set policy-options policy-statement nlri2ted_bgp term 1 from protocol bgp
   user@R0#set policy-options policy-statement nlri2ted_bgp term 1 then accept
   user@R0#set policy-options policy-statement pplb then load-balance per-packet
   user@R0#set policy-options policy-statement ted2nlri term 1 from protocol bgp-ls-epe
   user@R0#set policy-options policy-statement ted2nlri term 1 then accept
   

6. 配置 BGP 以启用到连接的对等方的 BGP-LS 路由通告，并定义 EPE 链路。由于快速分段是内部 TE 链路，因此此配置将创建外部 TE 链路。

   content_copy zoom_out_map

   [edit]
   user@R0#set protocols bgp group ebgp1 type external
   user@R0#set protocols bgp group ebgp1 family inet unicast
   user@R0#set protocols bgp group ebgp1 family traffic-engineering unicast

   user@R0#set protocols bgp group ebgp1 neighbor 192.168.2.2 egress-te-adj-segment epe_adj1_toR4 te-link-attribute admin-group brown
   

7. 使用策略启用流量工程数据库参数的导入和导出。

   content_copy zoom_out_map

   [edit]
   user@R0#set protocols mpls traffic-engineering database import l3-unicast-topology bgp-link-state
   user@R0#set protocols mpls traffic-engineering database import policy ted2nlri
   user@R0#set protocols mpls traffic-engineering database export policy nlri2ted_bgp
   user@R0#set protocols mpls traffic-engineering database export l3-unicast-topology
   

8. 为 LSP 路径计算配置 MPLS 管理组策略。

   content_copy zoom_out_map

   [edit]
   user@R0#set protocols mpls admin-groups red 0
   user@R0#set protocols mpls admin-groups blue 1
   user@R0#set protocols mpls admin-groups brown 5

   user@R1#set policy-options policy-statement ted2nlri_epe_stat term 1 then accept
   user@R1#set policy-options policy-statement ted2nlri_epe_stat term 2 from family traffic-engineering
   user@R1#set policy-options policy-statement ted2nlri_epe_stat term 2 from protocol bgp-ls-epe
   user@R1#set policy-options policy-statement ted2nlri_epe_stat term 2 then accept
   user@R1#set policy-options policy-statement ted2nlri_epe_stat term 3 from protocol isis
   user@R1#set policy-options policy-statement ted2nlri_epe_stat term 3 then reject
   

6. 配置 BGP 以启用到连接的对等方的 BGP-LS 路由通告，并定义 EPE 链路。由于快速分段是内部 TE 链路，因此此配置将创建外部 TE 链路。

   user@R1#set protocols rsvp interface all link-protection
   

10. 使用策略启用流量工程数据库参数的导入和导出。

    content_copy zoom_out_map

    [edit]
    user@R1#set protocols mpls traffic-engineering database import l3-unicast-topology bgp-link-state
    user@R1#set protocols mpls traffic-engineering database import policy ted2nlri_epe_stat
    user@R1#set protocols mpls traffic-engineering database export l3-unicast-topology
    

11. 为 LSP 路径计算配置 MPLS 管理组策略。

    content_copy zoom_out_map

    [edit]
    user@R1#set protocols mpls admin-groups red 0
    user@R1#set protocols mpls admin-groups blue 1
    user@R1#set protocols mpls admin-groups brown 5
    

12. 使用标签交换路径 （LSP） 配置 MPLS 并包括管理组。

分步过程

下面的示例要求您在各个配置层级中进行导航。有关导航 CLI 的信息，请参阅 CLI 用户指南中的在配置模式下使用 CLI 编辑器。

要配置设备 R4：

1. 将网络服务模式配置为增强型 IP。增强型 IP 将路由器的网络服务设置为增强型 Internet 协议，并使用增强模式功能。

   content_copy zoom_out_map

   [edit]
   user@R4#set chassis network-services enhanced-ip
   

   配置 enhanced-ip 语句并提交配置后，将显示以下警告消息，提示您重新启动路由器：

   content_copy zoom_out_map

   'chassis'
   WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior.
   commit complete

   重新启动将显示路由器上的 FPC。

2. 配置接口以启用 IP、MPLS 和 ISO 传输。

   user@R4#set interfaces ge-0/0/3 description To_R2
   user@R4#set interfaces ge-0/0/3 unit 0 family inet address 192.168.7.2/24
   user@R4#set interfaces ge-0/0/3 unit 0 family iso
   user@R4#set interfaces ge-0/0/3 unit 0 family mpls maximum-labels 8
   user@R4#set interfaces ge-0/0/4 description To_R5
   user@R4#set interfaces ge-0/0/4 unit 0 family inet address 192.168.13.1/24
   user@R4#set interfaces ge-0/0/4 unit 0 family iso
   user@R4#set interfaces ge-0/0/4 unit 0 family mpls maximum-labels 8
   

3. 配置环路接口以启用隧道端点和服务端点。

   [edit]
   user@R4#set interfaces lo0 unit 0 family inet address 10.4.4.4/32
   user@R4#set interfaces lo0 unit 0 family iso address 49.0001.0004.0404.0400
   

4. 配置路由选项以标识域中的路由器。

   content_copy zoom_out_map

   [edit]
   user@R4#set routing-options router-id 10.4.4.4
   user@R4#set routing-options autonomous-system 65200
   

5. 定义导入和导出策略。例如，配置将 EPE TE 链路从本地 TE 数据库 lsdist.0 导出到的策略以及要从 lsdist.0 中导入到本地 TE 数据库的策略。您可以配置策略以将 BGP 路由播发至对等方。

   content_copy zoom_out_map

   [edit]

   user@R4#set policy-options policy-statement nlri2bgp_stat term 1 from protocol express-segments
   user@R4#set policy-options policy-statement nlri2bgp_stat term 1 then accept
   user@R4#set policy-options policy-statement pplb then load-balance per-packet
   user@R4#set policy-options policy-statement ted2nlri_epe_stat term 1 from family traffic-engineering
   user@R4#set policy-options policy-statement ted2nlri_epe_stat term 1 from protocol express-segments
   user@R4#set policy-options policy-statement ted2nlri_epe_stat term 1 then accept
   user@R4#set policy-options policy-statement ted2nlri_epe_stat term 2 from family traffic-engineering
   user@R4#set policy-options policy-statement ted2nlri_epe_stat term 2 from protocol bgp-ls-epe
   user@R4#set policy-options policy-statement ted2nlri_epe_stat term 2 then accept
   user@R4#set policy-options policy-statement ted2nlri_epe_stat term 3 from protocol isis
   user@R4#set policy-options policy-statement ted2nlri_epe_stat term 3 then reject
   

6. 配置快速分段集和快速分段模板。快速段模板的作用是手动将继承的属性分配或覆盖给快速段，而不管底层属性是什么。快速段名称 r4-exp-set1 以底层端点为前缀，以便自动命名。

分步过程

下面的示例要求您在各个配置层级中进行导航。有关导航 CLI 的信息，请参阅 CLI 用户指南中的在配置模式下使用 CLI 编辑器。

要配置设备 R2：

1. 将网络服务模式配置为增强型 IP。增强型 IP 将路由器的网络服务设置为增强型 Internet 协议，并使用增强模式功能。

   content_copy zoom_out_map

   [edit]
   user@R2#set chassis network-services enhanced-ip
   

   配置 enhanced-ip 语句并提交配置后，将显示以下警告消息，提示您重新启动路由器：

   content_copy zoom_out_map

   'chassis'
   WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior.
   commit complete

   重新启动将显示路由器上的 FPC。

2. 配置接口以启用 IP、MPLS 和 ISO 传输。

分步过程

下面的示例要求您在各个配置层级中进行导航。有关导航 CLI 的信息，请参阅 CLI 用户指南中的在配置模式下使用 CLI 编辑器。

要配置设备 R5：

1. 将网络服务模式配置为增强型 IP。增强型 IP 将路由器的网络服务设置为增强型 Internet 协议，并使用增强模式功能。

   content_copy zoom_out_map

   [edit]
   user@R5#set chassis network-services enhanced-ip
   

   配置 enhanced-ip 语句并提交配置后，将显示以下警告消息，提示您重新启动路由器：

   content_copy zoom_out_map

   'chassis'
   WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior.
   commit complete

   重新启动将显示路由器上的 FPC。

2. 配置接口以启用 IP、MPLS 和 ISO 传输。

   user@R5#set interfaces ge-0/0/4 unit 0 family iso
   user@R5#set interfaces ge-0/0/4 unit 0 family mpls maximum-labels 8
   

3. 配置环路接口以启用隧道端点和服务端点。

   content_copy zoom_out_map

   [edit]
   user@R5#set interfaces lo0 unit 0 family inet address 10.5.5.5/32
   user@R5#set interfaces lo0 unit 0 family iso address 49.0001.0005.0505.0500
   

4. 配置路由选项以标识域中的路由器。

   content_copy zoom_out_map

   [edit]
   user@R5#set routing-options router-id 10.5.5.5
   user@R5#set routing-options autonomous-system 65200
   

5. 定义导入和导出策略。例如，配置将 EPE TE 链路从本地 TE 数据库 lsdist.0 导出到的策略以及要从 lsdist.0 中导入到本地 TE 数据库的策略。您可以配置策略以将 BGP 路由播发至对等方。

   content_copy zoom_out_map

   [edit]
   user@R5#set policy-options policy-statement nlri2bgp term 1 from family traffic-engineering
   user@R5#set policy-options policy-statement nlri2bgp term 1 then next-hop self
   user@R5#set policy-options policy-statement nlri2bgp term 1 then accept
   user@R5#set policy-options policy-statement nlri2ted_igp term 1 from traffic-engineering protocol isis-level-2
   user@R5#set policy-options policy-statement nlri2ted_igp term 1 then accept
   user@R5#set policy-options policy-statement pplb then load-balance per-packet
   user@R5#set policy-options policy-statement ted2nlri term 1 from protocol bgp-ls-epe
   user@R5#set policy-options policy-statement ted2nlri term 1 then accept

   user@R5#set protocols mpls interface ge-0/0/3.0 admin-group brown
   user@R5#set protocols mpls interface ge-0/0/4.0 admin-group brown
   user@R5#set protocols mpls interface all
   

7. 配置 BGP 以启用到连接的对等方的 BGP-LS 路由通告。

   content_copy zoom_out_map

   [edit]
   user@R5#set protocols bgp group RR2 type internal
   user@R5#set protocols bgp group RR2 family inet unicast
   user@R5#set protocols bgp group RR2 family traffic-engineering unicast
   user@R5#set protocols bgp group RR2 neighbor 10.1.1.1
   user@R5#set protocols bgp group RR2 neighbor 10.3.3.3
   user@R5#set protocols bgp group RR2 neighbor 10.6.6.6
   user@R5#set protocols bgp group RR2 neighbor 10.4.4.4
   user@R5#set protocols bgp cluster 10.5.5.5
   

8. 为 LSP 路径计算配置 MPLS 管理组策略。

   content_copy zoom_out_map

   [edit]
   user@R5#set protocols mpls admin-groups red 0
   user@R5#set protocols mpls admin-groups blue 1
   user@R5#set protocols mpls admin-groups brown 5

   content_copy zoom_out_map

   [edit]
   user@R5#set protocols mpls label-range static-label-range 7000 70000
   

10. 在所有 RSVP 接口上启用链路保护。使用链路保护，您可以将网络配置为围绕断开的链路快速重新路由流量。

    content_copy zoom_out_map

    [edit]
    user@R5#set protocols rsvp interface all link-protection

   commit complete

   重新启动将显示路由器上的 FPC。

2. 配置接口以启用 IP、MPLS 和 ISO 传输。

   content_copy zoom_out_map

   user@R3#set interfaces ge-0/0/0 description To_R2
   user@R3#set interfaces ge-0/0/0 unit 0 family inet address 192.168.6.2/24
   user@R3#set interfaces ge-0/0/0 unit 0 family iso
   user@R3#set interfaces ge-0/0/0 unit 0 family mpls maximum-labels 8
   user@R3#set interfaces ge-0/0/1 description To_R5
   user@R3#set interfaces ge-0/0/1 unit 0 family inet address 192.168.10.1/24
   user@R3#set interfaces ge-0/0/1 unit 0 family iso
   user@R3#set interfaces ge-0/0/1 unit 0 family mpls maximum-labels 8
   user@R3#set interfaces ge-0/0/2 description To_R6
   user@R3#set interfaces ge-0/0/2 unit 0 family inet address 192.168.11.1/24
   user@R3#set interfaces ge-0/0/2 unit 0 family iso
   user@R3#set interfaces ge-0/0/2 unit 0 family mpls maximum-labels 8
   user@R3#set interfaces ge-0/0/3 description To_R7

   user@R3#set interfaces ge-0/0/3 unit 0 family iso
   user@R3#set interfaces ge-0/0/3 unit 0 family mpls maximum-labels 8
   

3. 配置环路接口以启用隧道端点和服务端点。

   content_copy zoom_out_map

   [edit]
   user@R3#set interfaces lo0 unit 0 family inet address 10.3.3.3/32
   user@R3#set interfaces lo0 unit 0 family iso address 49.0001.0003.0303.0300
   

4. 配置路由选项以标识域中的路由器。

   content_copy zoom_out_map

   [edit]
   user@R3#set routing-options router-id 10.3.3.3
   user@R3#set routing-options autonomous-system 65200
   

5. 定义导入和导出策略。例如，配置将 EPE TE 链路从本地 TE 数据库 lsdist.0 导出到的策略以及要从 lsdist.0 中导入到本地 TE 数据库的策略。您可以配置策略以将 BGP 路由播发至对等方。

   user@R3#set policy-options policy-statement ted2nlri_epe_stat term 3 then reject
   

6. 配置 BGP 以启用对等方的 BGP-LS 路由通告并定义 EPE 链路。由于快速分段是内部 TE 链路，因此此配置将创建外部 TE 链路。

   user@R3#set protocols bgp group ebgp1 vpn-apply-export
   

7. 定义一种机制来自动（动态）创建快速段并将其插入 TE 数据库中，以便可以通过 BGP-LS 通告它们。在此示例中，将自动为所有底层 RSVP 隧道创建快速分段。这是通过使用策略配置模板来完成的，然后根据策略自动创建快速段。

   user@R3#set protocols express-segments segment-set set2 membership-policy expresspol2
   user@R3#set protocols express-segments traffic-engineering
   

8. 在接口上配置 IS-IS 和 MPLS 协议。

   user@R3#set protocols isis interface ge-0/0/3.0 passive
   user@R3#set protocols isis interface lo0.0 passive
   user@R3#set protocols isis level 1 disable
   user@R3#set protocols isis level 2 wide-metrics-only
   user@R3#set protocols mpls interface ge-0/0/0.0 admin-group brown
   user@R3#set protocols mpls interface ge-0/0/2.0 admin-group red
   user@R3#set protocols mpls interface ge-0/0/3.0 admin-group red
   user@R3#set protocols mpls interface ge-0/0/3.0 admin-group brown
   user@R3#set protocols mpls interface all
   

9. 使用策略启用流量工程数据库参数的导入和导出。

   content_copy zoom_out_map

   [edit]
   user@R3#set protocols mpls traffic-engineering database import l3-unicast-topology bgp-link-state
   user@R3#set protocols mpls traffic-engineering database import policy ted2nlri_epe_stat
   user@R3#set protocols mpls traffic-engineering database export l3-unicast-topology
   

10. 为 LSP 路径计算配置 MPLS 管理组策略。

    content_copy zoom_out_map

    [edit]
    user@R3#set protocols mpls admin-groups red 0
    user@R3#set protocols mpls admin-groups blue 1
    user@R3#set protocols mpls admin-groups brown 5
    

11. 使用标签交换路径 （LSP） 配置 MPLS 并包括管理组。

    content_copy zoom_out_map

    [edit]
    user@R3#set protocols mpls label-switched-path lsp3to1_a to 10.1.1.1
    user@R3#set protocols mpls label-switched-path lsp3to1_a admin-group include-any red
    user@R3#set protocols mpls label-switched-path lsp3to1_a admin-group include-any brown
    user@R3#set protocols mpls label-switched-path lsp3to4_a to 10.4.4.4
    user@R3#set protocols mpls label-switched-path lsp3to4_a admin-group include-any red
    user@R3#set protocols mpls label-switched-path lsp3to4_a admin-group include-any brown
    

12. 配置 MPLS 标签范围，为 EPE 链路分配静态标签。

    content_copy zoom_out_map

    [edit]
    user@R3#set protocols mpls label-range static-label-range 7000 70000
    

13. 在所有 RSVP 接口上启用链路保护。使用链路保护，您可以将网络配置为围绕断开的链路快速重新路由流量。

分步过程

下面的示例要求您在各个配置层级中进行导航。有关导航 CLI 的信息，请参阅 CLI 用户指南中的在配置模式下使用 CLI 编辑器。

要配置设备 R6：

1. 将网络服务模式配置为增强型 IP。增强型 IP 将路由器的网络服务设置为增强型 Internet 协议，并使用增强模式功能。

   content_copy zoom_out_map

   [edit]
   user@R6#set chassis network-services enhanced-ip
   

   配置 enhanced-ip 语句并提交配置后，将显示以下警告消息，提示您重新启动路由器：

   content_copy zoom_out_map

   'chassis'
   WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior.
   commit complete

   重新启动将显示路由器上的 FPC。

2. 配置接口以启用 IP、MPLS 和 ISO 传输。

   user@R6#set interfaces ge-0/0/0 description To_R2
   user@R6#set interfaces ge-0/0/0 unit 0 family inet address 192.168.9.2/24
   user@R6#set interfaces ge-0/0/0 unit 0 family iso

   user@R6#set interfaces ge-0/0/3 unit 0 family iso
   user@R6#set interfaces ge-0/0/3 unit 0 family mpls maximum-labels 8
   

3. 配置环路接口以启用隧道端点和服务端点。

   [edit]
   user@R6#set interfaces lo0 unit 0 family inet address 10.6.6.6/32
   user@R6#set interfaces lo0 unit 0 family iso address 49.0001.0006.0606.0600
   

4. 配置路由选项以标识域中的路由器。

   [edit]
   user@R6#set routing-options router-id 10.6.6.6
   user@R6#set routing-options autonomous-system 65200
   

5. 定义导入和导出策略。例如，配置将 EPE TE 链路从本地 TE 数据库 lsdist.0 导出到的策略以及要从 lsdist.0 中导入到本地 TE 数据库的策略。您可以配置策略以将 BGP 路由播发至对等方。

   user@R6#set policy-options policy-statement pplb then load-balance per-packet
   user@R6#set policy-options policy-statement ted2nlri_epe_stat term 1 from family traffic-engineering
   user@R6#set policy-options policy-statement ted2nlri_epe_stat term 1 from protocol static
   user@R6#set policy-options policy-statement ted2nlri_epe_stat term 1 then accept
   user@R6#set policy-options policy-statement ted2nlri_epe_stat term 2 from family traffic-engineering
   user@R6#set policy-options policy-statement ted2nlri_epe_stat term 2 from protocol bgp-ls-epe
   user@R6#set policy-options policy-statement ted2nlri_epe_stat term 2 then accept
   user@R6#set policy-options policy-statement ted2nlri_epe_stat term 3 from protocol isis
   user@R6#set policy-options policy-statement ted2nlri_epe_stat term 3 then reject
   

6. 配置 BGP 以启用对等方的 BGP-LS 路由通告并定义 EPE 链路。由于快速分段是内部 TE 链路，因此此配置将创建外部 TE 链路。

   user@R6#set protocols mpls interface ge-0/0/3.0 admin-group brown
   user@R6#set protocols mpls interface all
   

9. 使用策略启用流量工程数据库参数的导入和导出。

   content_copy zoom_out_map

   [edit]
   user@R6#set protocols mpls traffic-engineering database import l3-unicast-topology bgp-link-state
   user@R6#set protocols mpls traffic-engineering database import policy ted2nlri_epe_stat
   user@R6#set protocols mpls traffic-engineering database export l3-unicast-topology
   

10. 为 LSP 路径计算配置 MPLS 管理组策略。

    content_copy zoom_out_map

    [edit]
    user@R6#set protocols mpls admin-groups red 0
    user@R6#set protocols mpls admin-groups blue 1
    user@R6#set protocols mpls admin-groups brown 5
    

11. 使用标签交换路径 （LSP） 配置 MPLS 并包括管理组。

    content_copy zoom_out_map

    [edit]
    user@R6#set protocols mpls label-switched-path lsp6to1_a to 10.1.1.1
    user@R6#set protocols mpls label-switched-path lsp6to1_a admin-group include-any red
    user@R6#set protocols mpls label-switched-path lsp6to1_a admin-group include-any brown
    user@R6#set protocols mpls label-switched-path lsp6to4_a to 10.4.4.4
    user@R6#set protocols mpls label-switched-path lsp6to4_a admin-group include-any red
    user@R6#set protocols mpls label-switched-path lsp6to4_a admin-group include-any brown
    

12. 配置 MPLS 标签范围，为 EPE 链路分配静态标签。

    content_copy zoom_out_map

    [edit]
    user@R6#set protocols mpls label-range static-label-range 7000 70000
    

13. 在所有 RSVP 接口上启用链路保护。使用链路保护，您可以将网络配置为围绕断开的链路快速重新路由流量。

分步过程

下面的示例要求您在各个配置层级中进行导航。有关导航 CLI 的信息，请参阅 CLI 用户指南中的在配置模式下使用 CLI 编辑器。

要配置设备 R7：

1. 将网络服务模式配置为增强型 IP。增强型 IP 将路由器的网络服务设置为增强型 Internet 协议，并使用增强模式功能。

   content_copy zoom_out_map

   [edit]
   user@R7#set chassis network-services enhanced-ip
   

   配置 enhanced-ip 语句并提交配置后，将显示以下警告消息，提示您重新启动路由器：

   content_copy zoom_out_map

   'chassis'
   WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior.
   commit complete

   重新启动将显示路由器上的 FPC。

2. 配置接口以启用 IP、MPLS 和 ISO 传输。

   content_copy zoom_out_map

   user@R7#set interfaces ge-0/0/0 description To_R3
   user@R7#set interfaces ge-0/0/0 unit 0 family inet address 192.168.12.2/24
   user@R7#set interfaces ge-0/0/0 unit 0 family iso
   user@R7#set interfaces ge-0/0/0 unit 0 family mpls maximum-labels 8
   user@R7#set interfaces ge-0/0/1 description To_R6
   user@R7#set interfaces ge-0/0/1 unit 0 family inet address 192.168.15.2/24
   user@R7#set interfaces ge-0/0/1 unit 0 family iso
   user@R7#set interfaces ge-0/0/1 unit 0 family mpls maximum-labels 8
   

3. 配置环路接口以启用隧道端点和服务端点。

   content_copy zoom_out_map

   [edit]
   user@R7#set interfaces lo0 unit 0 family inet address 10.7.7.7/32
   user@R7#set interfaces lo0 unit 0 family inet address 10.7.7.71/32
   

4. 配置路由选项以标识域中的路由器。

   content_copy zoom_out_map

   [edit]
   user@R7#set routing-options router-id 10.7.7.7
   user@R7#set routing-options autonomous-system 65300
   user@R7#set routing-options static route 10.100.100.101/32 next-hop 10.100.100.100
   user@R7#set routing-options static route 10.100.100.101/32 resolve
   

5. 定义导入和导出策略。例如，配置将 EPE TE 链路从本地 TE 数据库 lsdist.0 导出到的策略以及要从 lsdist.0 中导入到本地 TE 数据库的策略。您可以配置策略以将 BGP 路由播发至对等方。

   content_copy zoom_out_map

   [edit]
   user@R7#set policy-options policy-statement nlri2bgp_epe term 1 from family traffic-engineering
   user@R7#set policy-options policy-statement nlri2bgp_epe term 1 from protocol bgp-ls-epe
   user@R7#set policy-options policy-statement nlri2bgp_epe term 1 then next-hop self
   user@R7#set policy-options policy-statement nlri2bgp_epe term 1 then accept
   user@R7#set policy-options policy-statement nlri2ted_bgp term 1 from protocol bgp
   user@R7#set policy-options policy-statement nlri2ted_bgp term 1 then accept
   user@R7#set policy-options policy-statement pplb then load-balance per-packet
   user@R7#set policy-options policy-statement ted2nlri term 1 from protocol bgp-ls-epe
   user@R7#set policy-options policy-statement ted2nlri term 1 then accept
   user@R7#set policy-options resolution-map map1 mode ip-color
   

6. 配置 BGP 以启用对等方的 BGP-LS 路由通告并定义 EPE 链路。由于快速分段是内部 TE 链路，因此此配置将创建外部 TE 链路。

   content_copy zoom_out_map

   [edit]
   user@R7#set protocols bgp group ebgp1 type external
   user@R7#set protocols bgp group ebgp1 family inet unicast

在 R1 上

user@R1>show route table mpls.0 protocol express-segments

mpls.0: 13 destinations, 13 routes (13 active, 0 holddown, 0 hidden)
+ = Active Route, - = Last Active, * = Both

意义

• 在输出中 show express-segments detail ，您可以看到快速段 （r1-exp-set1-10.6.6.6, r1-exp-set2-10.3.3.3）、快速段标签 （25, 24） 和底层 LSP （lsp1to6_a, lsp1to3_a） 的名称。

• 在输出中 show ted database topology-type express-segments detail ，您可以看到快速段条目已插入到 TE 数据库中。快速网段（虚拟 TE 链路）是动态创建的。使用的协议是 EXPRESS-SEG(0)。

• 在输出中 show route table mpls.0 protocol express-segments ，您可以看到快速段标签 （24,25）。由于快速分段是依赖于底层 LSP 的构造，因此快速分段标签将交换到底层 LSP 标签 （33,34），即 RSVP-LSP。

目的

验证始发节点是否将快速分段通告至其 eBGP/iBGP LS 邻接方。

操作

在操作模式下，运行以下命令：

• show route table lsdist.0- 验证 RIB BGP-LS 中的快速段是否正在播发。

• show route advertising-protocol bgp neighbor— 验证快速分段是否已发送到 eBGP/iBGP LS 邻居。

user@R1>show route table lsdist.0

lsdist.0: 25 destinations, 37 routes (25 active, 0 holddown, 0 hidden)

意义

• 在输出中 show route table lsdist.0 ，BGP 通告路由表中的路由。路由表是从 TE 数据库创建的。您可以看到快速段 （EXPRESS-SEG/6） 链接和 EPE 链接 （BGP-LS-EPE:0 }/1216）。

• 在输出中 show route advertising-protocol bgp 10.2.2.2 ，您可以看到 R1 播发的目标。快速段入到 TE 数据库中，该数据库被复制到 RIB。BGP-LS 将 RIB 播发至对等路由器。在对等体上，收到的 RIB 信息被复制到本地数据库中。此示例中的策略仅播发快速网段和 EPE 网段。

目的

验证入口节点是否通过 eBGP/iBGP LS 接收 TE 拓扑信息。

操作

在操作模式下，运行以下命令：

• show route receive-protocol bgp neighbor— 验证是否从 eBGP/iBGP LS 邻居接收了快速分段。

• show route table lsdist.0- 验证快速段是否在 BGP-LS RIB 中。

• show ted database topology-type l3-unicast detail— 验证快速分段是否已导入入口路由器的 TE 数据库。

• show spring-traffic-engineering lsp— 验证是否已成功计算并安装端到端 SR 策略。

意义

• 在输出中 show route receive-protocol bgp 10.1.1.1 ，它显示了入口路由器 （R0） 从 BGP 邻居接收的路由，其中描述了快速分段（虚拟 TE 链路）。

• 在输出中 show route table lsdist.0 ，它显示入口路由器 （R0） 已接收的路由以及它们是否插入到 RIB 中 lsdist.0 。它还显示 RIB 是否已 lsdist.0 复制到本地 TE 数据库中。

• 在输出中 show ted database topology-type l3-unicast detail ，路由将复制到本地 TE 数据库中。这是一个r1-exp-set1-10.6.6.6终点为 10.6.6.6 的快速段，并在 R1 上成功创建。R1 已播发快递段，R0 已将其插入本地 TE 数据库。您还可以看到 EPE 段 （epe_adj1_toR7）。

• 在输出中 show spring-traffic-engineering lsp ，您可以看到 SR 策略已启动。它表明您现在可以计算多域端到端（R0 到 R7）SR 策略。

• 在输出中 show spring-traffic-engineering lsp detail ，您可以看到所选的标签。computelsp1在LSP中，标签7104是EPE段，21是快递段，7167也是EPE段。它表明您现在可以计算多域端到端（R0 到 R7）SR 策略。

分步过程

下面的示例要求您在各个配置层级中进行导航。有关导航 CLI 的信息，请参阅 CLI 用户指南中的在配置模式下使用 CLI 编辑器。

要配置设备 R0：

1. 将网络服务模式配置为增强型 IP。增强型 IP 将路由器的网络服务设置为增强型 Internet 协议，并使用增强模式功能。

   content_copy zoom_out_map

   [edit]
   user@R0#set chassis network-services enhanced-ip
   

   配置 enhanced-ip 语句并提交配置后，将显示以下警告消息，提示您重新启动路由器：

   content_copy zoom_out_map

   'chassis'
   WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior.
   commit complete

   重新启动将显示路由器上的 FPC。

2. 配置接口以启用 IP、MPLS 和 ISO 传输。

4. 定义导入和导出策略。例如，配置将 EPE TE 链路从本地 TE 数据库 lsdist.0 导出到的策略以及要从 lsdist.0 中导入到本地 TE 数据库的策略。您可以配置策略以将 BGP 路由播发至对等方。

   路由过滤器路由从外部 AS 播发。

分步过程

下面的示例要求您在各个配置层级中进行导航。有关导航 CLI 的信息，请参阅 CLI 用户指南中的在配置模式下使用 CLI 编辑器。

要配置设备 R1：

1. 将网络服务模式配置为增强型 IP。增强型 IP 将路由器的网络服务设置为增强型 Internet 协议，并使用增强模式功能。

分步过程

下面的示例要求您在各个配置层级中进行导航。有关导航 CLI 的信息，请参阅 CLI 用户指南中的在配置模式下使用 CLI 编辑器。

要配置设备 R4：

1. 将网络服务模式配置为增强型 IP。增强型 IP 将路由器的网络服务设置为增强型 Internet 协议，并使用增强模式功能。

   [edit]
   user@R4#set chassis network-services enhanced-ip
   

   配置 enhanced-ip 语句并提交配置后，将显示以下警告消息，提示您重新启动路由器：

   content_copy zoom_out_map

   'chassis'
   WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior.
   commit complete

   重新启动将显示路由器上的 FPC。

2. 配置接口以启用 IP、MPLS 和 ISO 传输。

   content_copy zoom_out_map

   [edit]
   user@R4#set routing-options rib-groups color-to-inet3 import-rib [ inetcolor.0 inet.3 ]

7. 配置 BGP 以启用到连接的对等方的 BGP-LS 路由通告，并定义 EPE 链路。由于快速分段是内部 TE 链路，因此此配置将创建外部 TE 链路。

分步过程

下面的示例要求您在各个配置层级中进行导航。有关导航 CLI 的信息，请参阅 CLI 用户指南中的在配置模式下使用 CLI 编辑器。

要配置设备 R2：

1. 将网络服务模式配置为增强型 IP。增强型 IP 将路由器的网络服务设置为增强型 Internet 协议，并使用增强模式功能。

   [edit]
   user@R2#set chassis network-services enhanced-ip
   

   配置 enhanced-ip 语句并提交配置后，将显示以下警告消息，提示您重新启动路由器：

   content_copy zoom_out_map

   'chassis'
   WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior.
   commit complete

   重新启动将显示路由器上的 FPC。

2. 配置接口以启用 IP、MPLS 和 ISO 传输。

分步过程

下面的示例要求您在各个配置层级中进行导航。有关导航 CLI 的信息，请参阅 CLI 用户指南中的在配置模式下使用 CLI 编辑器。

要配置设备 R5：

1. 将网络服务模式配置为增强型 IP。增强型 IP 将路由器的网络服务设置为增强型 Internet 协议，并使用增强模式功能。

   content_copy zoom_out_map

   [edit]
   user@R5#set chassis network-services enhanced-ip
   

   配置 enhanced-ip 语句并提交配置后，将显示以下警告消息，提示您重新启动路由器：

   content_copy zoom_out_map

   'chassis'
   WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior.
   commit complete

   重新启动将显示路由器上的 FPC。

2. 配置接口以启用 IP、MPLS 和 ISO 传输。

分步过程

下面的示例要求您在各个配置层级中进行导航。有关导航 CLI 的信息，请参阅 CLI 用户指南中的在配置模式下使用 CLI 编辑器。

要配置设备 R3：

1. 将网络服务模式配置为增强型 IP。增强型 IP 将路由器的网络服务设置为增强型 Internet 协议，并使用增强模式功能。

   content_copy zoom_out_map

   [edit]
   user@R3#set chassis network-services enhanced-ip
   

   配置 enhanced-ip 语句并提交配置后，将显示以下警告消息，提示您重新启动路由器：

   content_copy zoom_out_map

   'chassis'
   WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior.
   commit complete

   重新启动将显示路由器上的 FPC。

2. 配置接口以启用 IP、MPLS 和 ISO 传输。

分步过程

下面的示例要求您在各个配置层级中进行导航。有关导航 CLI 的信息，请参阅 CLI 用户指南中的在配置模式下使用 CLI 编辑器。

要配置设备 R6：

1. 将网络服务模式配置为增强型 IP。增强型 IP 将路由器的网络服务设置为增强型 Internet 协议，并使用增强模式功能。

   content_copy zoom_out_map

   [edit]
   user@R6#set chassis network-services enhanced-ip
   

   配置 enhanced-ip 语句并提交配置后，将显示以下警告消息，提示您重新启动路由器：

   content_copy zoom_out_map

   'chassis'
   WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior.
   commit complete

   重新启动将显示路由器上的 FPC。

2. 配置接口以启用 IP、MPLS 和 ISO 传输。

   user@R6#set interfaces lo0 unit 0 family inet6 address 2001:db8:abcd::06:06:06:06/128
   

4. 定义导入和导出策略。例如，配置将 EPE TE 链路从本地 TE 数据库 lsdist.0 导出到的策略以及要从 lsdist.0 中导入到本地 TE 数据库的策略。您可以配置策略以将 BGP 路由播发至对等方。

   user@R6#set policy-options policy-statement ted2nlri_epe_stat term 1 then accept
   user@R6#set policy-options policy-statement ted2nlri_epe_stat term 2 from family traffic-engineering
   user@R6#set policy-options policy-statement ted2nlri_epe_stat term 2 from protocol bgp-ls-epe
   user@R6#set policy-options policy-statement ted2nlri_epe_stat term 2 then accept
   user@R6#set policy-options policy-statement ted2nlri_epe_stat term 3 from protocol isis
   user@R6#set policy-options policy-statement ted2nlri_epe_stat term 3 then reject
   

5. 配置路由选项以标识域中的路由器。

   content_copy zoom_out_map

   [edit]
   user@R6#set routing-options router-id 10.6.6.6
   user@R6#set routing-options autonomous-system 65200
   

6. 定义 RIB 组以将 inetcolor.0 复制到 inet.3 路由表。

   content_copy zoom_out_map

   [edit]
   user@R6#set routing-options rib-groups color-to-inet3 import-rib [ inetcolor.0 inet.3 ]
   

7. 配置 BGP 以启用对等方的 BGP-LS 路由通告并定义 EPE 链路。由于快速分段是内部 TE 链路，因此此配置将创建外部 TE 链路。

   content_copy zoom_out_map

   [edit]
   user@R6#set protocols bgp group ibgp1 type internal
   user@R6#set protocols bgp group ibgp1 local-address 10.6.6.6
   user@R6#set protocols bgp group ibgp1 family traffic-engineering unicast
   user@R6#set protocols bgp group ibgp1 export nlri2bgp_epe
   user@R6#set protocols bgp group ibgp1 neighbor 10.2.2.2
   user@R6#set protocols bgp group ibgp1 neighbor 10.5.5.5
   user@R6#set protocols bgp group ebgp1 type external
   user@R6#set protocols bgp group ebgp1 family traffic-engineering unicast
   user@R6#set protocols bgp group ebgp1 export nlri2bgp_stat
   user@R6#set protocols bgp group ebgp1 neighbor 192.168.15.2 peer-as 65300
   user@R6#set protocols bgp group ebgp1 neighbor 192.168.15.2 egress-te-adj-segment epe_adj1_toR7 label 7167

   user@R6#set protocols bgp group ebgp1 neighbor 192.168.15.2 egress-te-adj-segment epe_adj1_toR7 te-link-attribute te-metric 20
   user@R6#set protocols bgp group ebgp1 neighbor 192.168.15.2 egress-te-adj-segment epe_adj1_toR7 te-link-attribute igp-metric 10
   user@R6#set protocols bgp group ebgp1 neighbor 192.168.15.2 egress-te-adj-segment epe_adj1_toR7 te-link-attribute admin-group red
   user@R6#set protocols bgp group ebgp1 neighbor 192.168.15.2 egress-te-adj-segment epe_adj1_toR7 te-link-attribute admin-group brown
   

8. 定义一种机制来自动（动态）创建快速段并将其插入 TE 数据库中，以便可以通过 BGP-LS 通告它们。在此示例中，将自动为所有底层 SR 隧道创建快速分段。这是通过使用策略配置模板来完成的，然后根据策略自动创建快速段。

   user@R6#set protocols isis traffic-engineering l3-unicast-topology
   user@R6#set protocols isis traffic-engineering advertisement always
   user@R6#set protocols isis export prefix-sid

10. 使用策略启用流量工程数据库参数的导入和导出。

分步过程

下面的示例要求您在各个配置层级中进行导航。有关导航 CLI 的信息，请参阅 CLI 用户指南中的在配置模式下使用 CLI 编辑器。

要配置设备 R7：

1. 将网络服务模式配置为增强型 IP。增强型 IP 将路由器的网络服务设置为增强型 Internet 协议，并使用增强模式功能。

   content_copy zoom_out_map

   [edit]
   user@R7#set chassis network-services enhanced-ip
   

   配置 enhanced-ip 语句并提交配置后，将显示以下警告消息，提示您重新启动路由器：

   content_copy zoom_out_map

   'chassis'
   WARNING: Chassis configuration for network services has been changed. A system reboot is mandatory. Please reboot the system NOW. Continuing without a reboot might result in unexpected system behavior.
   commit complete

   重新启动将显示路由器上的 FPC。

2. 配置接口以启用 IP、MPLS 和 ISO 传输。

4. 定义导入和导出策略。例如，配置将 EPE TE 链路从本地 TE 数据库 lsdist.0 导出到的策略以及要从 lsdist.0 中导入到本地 TE 数据库的策略。您可以配置策略以将 BGP 路由播发至对等方。

   路由过滤器路由从外部 AS 播发。

   user@R7#set routing-options static route 10.100.100.101/32 resolve
   user@R7#set routing-options forwarding-table export pplb

6. 配置 BGP 以启用对等方的 BGP-LS 路由通告并定义 EPE 链路。由于快速分段是内部 TE 链路，因此此配置将创建外部 TE 链路。

目的

验证是否正确创建了快速段。

操作

在操作模式下，运行以下命令：

• show express-segments detail- 验证是否已创建快速段。

• show ted database topology-type express-segments detail- 验证新创建的快速段是否已插入到 TE 数据库中。

• show route table mpls.0 protocol express-segments- 验证是否已创建转发条目。

意义

• 在输出中 show express-segments detail ，您可以看到快速段 （set1sr-10.3.3.3）、快速段标签 （16） 和底层 LSP （lsp1to3_sr） 的名称。

• 在输出中 show ted database topology-type express-segments detail ，您可以看到快速段条目已插入到 TE 数据库中。快速网段（虚拟 TE 链路）是动态创建的。使用的协议是 EXPRESS-SEG(0)。

• 在输出中 show route table mpls.0 protocol express-segments ，您可以看到快速段标签 （16）。由于快速分段是依赖于底层 LSP 的构造，因此快速分段标签将交换到底层 SR-TE 标签 （801003）。
