Simple configuration of Anycast RP

MSDP is invaluable protocol when you need to keep your multicast flowing no matter what happens to your RP – just keep few of them up and running at all times.

On RP1:


ip pim rp-address 10.10.10.1
!
Interface loopback 0
Ip address 10.10.10.1 255.255.255.255
!
Interface loopback 1
Ip address 10.11.11.1 255.255.255.255
!
Ip msdp peer 10.11.11.2 connect-source loopback 1
Ip msdp originator-id loopback 1

On RP2:
ip pim rp-address 10.10.10.1
!
Interface loopback 0
Ip address 10.10.10.1 255.255.255.255
!
Interface loopback 1
Ip address 10.11.11.2 255.255.255.255
!
Ip msdp peer 10.11.11.1 connect-source loopback 1
Ip msdp originator-id loopback 1

Obviously you can have more then 2 RPs – analogy is clear.

Configuration on all other routers would be:


Ip pim rp-address 10.10.10.1
No ip pim dm-fallback
