Configuring MSDP Anycast RP

To configure MSDP Anycast RP, you must perform the following tasks:

  • Configure a loopback interface with the anycast RP address on each of the RPs within the domain and enable PIM-SM on these interfaces.
  • Ensure that the anycast RP address is leaked into the IGP domain. This is typically done by enabling the IGP on the loopback interface (in passive mode) or redistributing the connected loopback IP address into the IGP.
NOTE
The anycast RP address *must* not be the IGP router-id.
  • Enable PIM-SM on all interfaces on which multicast routing is desired.
  • Enable an IGP on each of the loopback interfaces and physical interfaces configured for PIM-SM.
  • Configure loopback interfaces with unique IP addresses on each of the RPs for MSDP peering. This loopback interface is also used as the MSDP originator-id.
  • The non-RP PIM-SM routers may be configured to use the anycast RP address statically or dynamically (by the PIMv2 bootstrap mechanism).
