服务链设计和实施
有关服务链的概述,请参阅数据中心交换矩阵蓝图架构组件中的服务链部分。
以下部分介绍如何在 EVPN VXLAN 网络中实施服务链和组播服务链。
服务链
服务链设计
图 1 显示了服务链配置的逻辑视图。其中显示了一个主干的左侧和右侧 VRF 配置。SRX 系列路由器是 PNF,并执行服务链。
主干的流量:
来自叶租户的流量进入租户 VRF-151,并发往连接到租户 VRF-152 的网络。
由于没有从 VRF-151 到 VRF-152 的路由,因此将使用从 PNF 接收的路由执行默认路由查找。
从 PNF 接收默认路由后,VRF-151 通过 IRB.4088 将流量路由到 PNF。
流量到达 PNF,PNF 执行服务链。流量使用从 EBGP 接收的路由转发出 ae26.1。
流量现在到达租户 VRF-152,并按照常规路由查找和转发操作,向叶租户转发。

使用组播实现服务链
采用组播设计的服务链
图 2 显示了服务链配置的逻辑视图。VRF 路由实例和 IRB 接口均配置在同一主干上。
在这种设计中,我们使用 SRX 系列路由器作为 PNF 和 PIM 网关来执行服务链。
组播接收器开始发送 IGMP 报告时主干 2 的流量:
叶设备侦听 IGMP 报告,并将 EVPN Type 6 路由播发至主干,以通知主干有关组播接收器。
主干会根据 VNI 映射接收 EVPN 6 类路由,并创建 PIM 加入 (*。G) VRF-152 中的条目。
主干配置包括 PIM 网关上的 RP 地址。但是,在 VRF-152 路由实例上,只有一个通过 PNF 指向 RP 的默认路由。
接收器端 IRB(irb.605、irb.606 irb.607、irb.608)上的 PIM 指定路由器 (DR) 发送 PIM 加入 (*)。G) 向 irb.4089 上的 PNF 设备方向发展。
PNF 设备会创建 PIM (*.G) 条目,ae26.1 作为传出接口。
PNF 配置了 RP。
在 PNF 上,RP 也在 PNF 上配置,并且查找 PIM RP 指向主干上的 VRF-151 接口 ae26.0 -> 接口
PIM 加入到达 irb.4088 上的 VRF-151,并创建一个 PIM (*,G) 状态(以 irb.4088 作为传出接口),并查找 RP 点至 irb.4086。
主干会将 irb.4086 上的 PIM 加入条目发送至 PIM 网关。
PIM 网关在 ae10.2 上接收 PIM (*,G) 加入。
VRF-151 上的组播源开始发送数据包时,主干 2 的流量:
VRF-151 创建一个 PIM (*,G) 条目,并将 irb.4088 用作传出接口,也可通过 irb.4086 创建 RP。
主干 2 发送两个数据包—一个向 irb.4088 上的 PNF,一个向 irb.4086 上的 PIM 网关发送。
当 PNF 收到数据包时:
PNF 基于 PIM ( *.G ) 条目,它使用传出接口 ae26.1 创建的
组播流量到达 VRF-512 中的 irb.4089,并转发到叶上的接收器。
当 PIM 网关收到数据包时,它会根据其 (*,G) PIM 条目转发数据包,而传出接口作为 ae10.2。
当流量从主干 2 上的 PIM 网关到达 irb.4086 时,主干 2 会删除 RPT/共享树。

验证使用组播的服务链
本节介绍如何使用组播配置服务链。请注意以下几点:
组播源在 VRF-151 - VLAN 601 上
组播接收器位于 VRF-152 - VLAN 606 上
- 显示 VRF-152 上为 PIM 配置的接口。此命令显示属于 DR 的接口。 content_copy zoom_out_map
