This section provides examples for implementing PIM-SM inter-domain multicast through MSDP and inter-AS multicast through static RPF peers as well as configuring anycast RP in a PIM-SM domain.
You can set up MSDP peer relationships between Rendezvous Points (RPs) in different PIM-SM domains in the same AS or between the RPs in different ASs that have set up External BGP (EBGP) peer relationships so that hosts can receive multicast data from the source in another PIM-SM domain in the AS or from the source in another AS.
You can set up MSDP peer relationships between Rendezvous Points (RPs) in different PIM-SM domains in the same AS or static Reverse Path Forwarding (RPF) relationships between the RPs in different ASs so that hosts can receive multicast data from the source in another PIM-SM domain in the AS or from the source in another AS.
If there are multiple multicast sources and receivers in a PIM-SM domain, you can configure MSDP peer relationships between Candidate-RPs (C-RPs) and configure anycast Rendezvous Point (RP) to implement load sharing.
