Example: Configuring MBGP MVPN Senders and Receivers using PIM SM and RSVP-TE Provider Tunnels

This section contains a configuration example and commands you can issue to verify multiprotocol BGP multicast VPN sender and receiver site routers.

In the example shown in Figure 1, there are three routers: PE1, the CE router, and PE2. Each router supports a specific role as a sender, receiver, or sender and receiver. This example does not represent a complete network.

Router PE1 is configured as a multicast sender and receiver site in VPN A, and as a multicast receiver site in VPN B. The relevant configuration for Router PE1 follows.

Router PE1

[edit]routing-instances {vpn-a {instance-type vrf;interface so-6/0/0.0;interface so-6/0/1.0;provider tunnel { rsvp-te {label-switched-path-template default-template;}}protocols {mvpn {route-target {export-target unicast target:1:4;import-target unicast sender target target:1:4 receiver;}}}route-distinguisher 65535:0;vrf-target target:1:1;routing-options {auto-export;static {route 172.16.0.0/16 next-hop so-0/0/0.0;route 172.17.0.0/16 next-hop so-6/0/1.0;}}}}

Router PE2 is configured as a multicast sender-only site. The relevant configuration for Router PE2 follows.

Verifying Your Work

To verify correct operation of multiprotocol BGP multicast VPNs, use the following commands:

show mvpn c-multicast
show mvpn instance
show mvpn neighbor

The following sections show the output of these commands used with the configuration example:

show mvpn c-multicast

Router> show mvpn c-multicast
