The example shown in Figure 88 is an anycast-enabled network with three RPs connected in a
triangular mesh topology. Loopback 2 in RP 1, RP 2, and RP 3 have the same IP address, which is
the anycast RP address. Loopback 1 in RP1, RP2, and RP3 have different IP addresses and are
configured as MSDP peering IP addresses in a triangular mesh configuration.
OSPF is configured as the IGP for the network and all of the devices are in OSPF area 0. This
example demonstrates only anycast RP configurations. Assuming a PIM-SM network with three
anycast RPs configured, the RP address is configured to be the anycast RP address that was
configured on Loopback interface 2 of RP1, RP2, and RP3. Based on the IGP routes, all routers in
the network are registered to the shortest path anycast RP. This shares the load between all the
RPs, and provides hot backup.
