INE Vol 1 multicast - Lab 11 - Anycast RP

Notes:

This lab demonstrates an application of MSDP by using AnycastRP in a single PIM-SM domain. AnycastRP is used to provide RP redundancy within a PIM-SM domain and can provide load balancing.

Anycast RP uses an additional loopback on 2 or more routers with the same /32 ip address. This IP address is now the IP for the RP and must be known to all PIM-SM routers either via a static rp, autorp, or bsr.

MSDP is used to connect the 2 or more routers with this additional loopback so they can exchange RP source information.

The same reference as the last lab provides a better description and details.

R1 and R5 as the RP using AnycastRP (similar config on R5)
