　　In a large site (many layer 3 routers) you may choose to use auto-RP (Cisco proprietary)， or anycast RP， or BSR (but note that BSR does not support scoped addresses properly) to set up your Rendezvous Point. It would also be good to configure a redundant RP.

　　Rate Limiting

　　Rate limiting should be applied on any small link to prevent unwanted flooding of the link by multicast traffic. Care should be paid to shared infrastructure (such as an RNO switch) to ensure the rate limits for all members are the same， and favour the member with the fullest link， otherwise that member will suffer link saturation. On a per-interface basis you can apply the following (units are kilobits per second):

　　interface XYZ0/0

　　ip multicast rate-limit in 600
