1. All the RPs serving a given group are configured with an identical anycast address.
2. Sources then register with the topologically closest RP.
3. RPs use MSDP to peer with each other using a unique address.

Configuring Anycast RP
To configure anycast RP, use the following commands.
1. In each routing domain that has multiple RPs serving a group, create a Loopback interface on each RP serving the group
with the same IP address.
CONFIGURATION mode
interface loopback
2. Make this address the RP for the group.
CONFIGURATION mode
ip pim rp-address
3. In each routing domain that has multiple RPs serving a group, create another Loopback interface on each RP serving the
group with a unique IP address.
CONFIGURATION mode
interface loopback
4. Peer each RP with every other RP using MSDP, specifying the unique Loopback address as the connect-source.
CONFIGURATION mode
Multicast Source Discovery Protocol (MSDP)
