 | | Example 2 As in Example 1, the network administrator of 2001:DB8::/32 wants to set up the RP but, to make it more flexible, wants to place it on a specifically routed subnet and wants to keep larger address space for group allocations. |
 | | As the address of the RP is tied to the multicast address, the RP failure management becomes more difficult, as the deployed failover or redundancy mechanisms (e.g., BSR, Anycast-RP with MSDP) cannot be used as-is. However, Anycast-RP using PIM provides equal redundancy; this described briefly in Section 6.1. |
 | | RP Redundancy A technique called "Anycast RP" is used within a PIM-SM domain to share an address and multicast state information between a set of RPs mainly for redundancy purposes. |
