MSDP Anycast RP Configuration on Cisco IOS XR Software: Example

Anycast RP allows two or more rendezvous points (RPs) to share the load for source registration and to act
as hot backup routers for each other. MSDP is the key protocol that makes Anycast RP possible.
In Anycast RP, two or more RPs are configured with the same IP address on loopback interfaces. Configure
the Anycast RP loopback address with a 32-bit mask, making it a host address. Configure all downstream
routers to "know" that the Anycast RP loopback address is the IP address of the local RP. IP routing
automatically selects the topologically closest RP for each source and receiver.
As a source may register with one RP and receivers may join to a different RP, a method is needed for the
RPs to exchange information about active sources. This information exchange is done with MSDP.
