Configuring PE2 for MX Series Router Cloud CPE Draft-Rosen Multicast VPN Services

 

Enabling PIM Version 2 on the IRB and Loopback Interfaces

To enable PIM on the IRB and loopback interfaces:

  • Enable PIM on the IRB interface and configure the PIM mode as sparse.

Configuring the Loopback Interface and Assigning a VPN Private Address

Configure an additional logical interface on the loopback interface of the PE router, and assign an IP address from the VPN address space.

  • To configure the loopback interface:

Configuring the Routing Instance

Configure a VPN routing instance that includes the IRB interface and the loopback interface. To configure the routing instance:

  1. Configure the name of the routing instance.
  2. Configure the routing instance as a VRF instance.
  3. Reference the IRB interface in the routing instance by specifying irb.vlan-id.
  4. Reference the loopback interface in the routing instance.
  5. Specify a route distinguisher that is attached to the route, enabling you to distinguish which VPN the route belongs to. Each routing instance must have a unique route distinguisher associated with it.
  6. Specify the VPN’s community. VRF import and export policies are automatically generated.
  7. Map the inner label of a packet to a specific VRF table. This enables examination of encapsulated IP headers.
  8. Configure the group address for the Layer 3 VPN in the service provider’s network.

Configuring the BSR and RP in the Routing Instance

To configure the BSR and RP:

  1. Configure the BSR. Make sure to set different priorities on the PE routers.
  2. Configure a candidate RP in the VRF. Make sure to set different priorities on the PE routers.
