Verifying Multiprotocol BGP Multicast VPNs

Consider the example shown in Figure 83. In this example, there are three PE routers: PE1, PE2, and PE3. In this example, all three multiprotocol BGP-based MPLS VPNs are both sender and receiver sites.

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.

Verifying Your Work

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

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