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.
