In this design:
The access layer uses switches that support both IGMP snooping (Catalyst 3550 and Catalyst 4006 with Supervisor III) and CGMP Client (Catalyst 3524-PWR).
The RPs are located on the two core layer switches (Catalyst 6509-left-core and Catalyst 6509-right-core).
PIM-SM is configured on all distribution switches and core switches. Anycast RP is configured for fast recovery of IP multicast traffic. PIM-SM and MSDP are enabled on both core switches. Each distribution switch points to the Anycast RP address as its RP. MSDP is used to synchronize SA states between both core switches.
