Multiprotocol BGP Multicast VPNs Example

This section contains a configuration example and commands you can issue to verify a routing matrix configuration.

In the example shown in Figure 78, there are three routers: PE1, the CE router, and PE2.

Router PE1 is configured with multicast VPN A, which is a sender and a receiver site, and multicast VPN B, which is a receiver site.

}




protocols {

}


}


route-distinguisher 65535:1;

}

The sample configuration for 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:
