In the remaining output for this example, the show pim join output shows group participation. Also displayed is the output from the show multicast route extensive and show multicast next-hop commands. The join output for PIM within a VPN will reference the group 229.1.1.1, while the service provider side of the network will reference the join information for group 239.1.1.1 (which is the VPN group ID). In the show multicast route extensive output, you can view the group, sender, and upstream interface toward the sender.
