Configuring the PE Router for MX Series Router Cloud CPE Multiple Ethernet Interface Services (One Bridge Domain per VLAN)

In this procedure you configure two VLANs for the subscriber and one bridge domain and one IRB interface per VLAN. You also need to configure a VRF routing instance for the subscriber VPN site and reference each of the IRB (one for each subscriber VLAN) as the interface.

Complete the following tasks to configure multiple Ethernet interfaces with cCPE services with one bridge domain per VLAN:

1. Configuring the Subscriber Access Link and VLANs for MX Series Router Cloud CPE Multiple Ethernet Interface Services
2. Configuring the IRB Interfaces for MX Series Router Cloud CPE Multiple Ethernet Interface Services
3. Configuring the Bridge Domains for MX Series Router Cloud CPE Multiple Ethernet Interface Services
4. Configuring the Routing Instance for MX Series Router Cloud CPE Multiple Ethernet Interface Services

Configuring the Subscriber Access Link and VLANs for MX Series Router Cloud CPE Multiple Ethernet Interface Services

1. Configure the physical interface.
   [edit]user@host# edit interfaces ge-1/2/3 user@host# set vlan-tagginguser@host# set encapsulation flexible-ethernet-services
2. Configure the first logical interface and VLAN.
   [edit interfaces ge-1/2/3]user@host# edit unit 105 user@host# set encapsulation vlan-bridgeuser@host# set vlan-id 105 user@host# set family bridge
3. Configure the second logical interface and VLAN.
   [edit interfaces ge-1/2/3 unit 105]user@host# upuser@host# edit unit 106 [edit interfaces ge-1/2/3 unit 106]user@host# set encapsulation vlan-bridgeuser@host# set vlan-id 106 user@host# set family bridge
4. Review your configuration.
   [edit interfaces ge-1/2/3 unit 106]user@host# upuser@host# show

   unit 105 {
       encapsulation vlan-bridge;
       vlan-id 105;
       family bridge;
   }
   unit 106 {
       encapsulation vlan-bridge;
       vlan-id 106;
       }
   

Configuring the IRB Interfaces for MX Series Router Cloud CPE Multiple Ethernet Interface Services

1. Configure the first IRB interface.
   [edit]user@host# edit interfaces irb unit 105 family inet address 192.168.1.1/24
2. Configure the second IRB interface.
   [edit interfaces irb unit 105]user@host# up[edit interfaces irb]user@host# edit unit 106 family inet address 192.168.2.1/24
3. Review the configuration.
   [edit interfaces irb unit 106 family inet address 192.168.2.1/24]user@host# upuser@host# upuser@host# up[edit interfaces irb]user@host# show

   unit 105 {
       family inet {
           address 192.168.1.1/24;
       }
   }
   unit 106 {
       family inet {
           address 192.168.2.1/24;
       }
   }

Configuring the Bridge Domains for MX Series Router Cloud CPE Multiple Ethernet Interface Services

1. Configure the first bridge domain.
   [edit]user@host# edit bridge-domains bd-105 user@host# set vlan-id 105 user@host# set interface ge-1/2/3.105user@host# set routing-interface irb.105
2. Configure the second bridge domain.
   [edit bridge-domains bd-105]user@host# upuser@host# edit bd-106 user@host# set vlan-id 106 user@host# set interface ge-1/2/3.106user@host# set routing-interface irb.106
3. Review the configuration.
   [edit bridge-domains]user@host# show

   bd-105 {
       vlan-id 105;
       interface ge-1/2/3.105;
       routing-interface irb.105;
   }
   bd-106 {
       vlan-id 106;
       interface ge-1/2/3.106;
       routing-interface irb.106;
   }
   

Configuring the Routing Instance for MX Series Router Cloud CPE Multiple Ethernet Interface Services

1. Configure the name of the routing instance.
   [edit]user@host# edit routing-instances ccpe1
2. Configure the VRF routing instance.
   [edit routing-instances ccpe1]user@host# set instance-type vrf
3. Reference the first IRB interface.
   [edit routing-instances ccpe1]user@host# set interface irb.105
4. Reference the second IRB interface.
   [edit routing-instances ccpe1]user@host# set interface irb.106
5. Review the configuration.
   [edit routing-instances ccpe1]user@host# show

   instance-type vrf;
   interface irb.105;
   interface irb.106;
