IP Multicast in a Site-to-Site VPN
Multicast Site-to-Site VPN Deployment
Multicast VPN Topology
This section provides information and sample configurations for deploying Anycast RP in a WAN.
Branch and Head-End
The IP multicast configuration steps for the branch and head-end routers are as follows: Enable IP multicast routing. Enable IP PIM Sparse Mode on each interface that will receive and forward multicast traffic.
Identify the RP for the router. With Anycast RP, the address defined is the Loopback address that is duplicated on each participating Anycast RP router. (Loopback 1 - 10.6.2.1).
Following is the basic multicast configuration for Branch1.
