VRF with RP

team,

is there a way to force VRF joining multiple RPs as a VRF can join only one RP multicast at a time?

Not only vrf but also in global you can config one RP for each multicast.

In vrf and multicast I think it hard

Try with global and config multi rp one for each multicast.

Hello
mc within a vrfs would be the same as in the global route table
As long as your unicast routing is all setup you should just enable mc routing to your vrf - Apply pim to the vrf interfaces and specify the RPs either staticky or dynamically like BSR

hi boss,

if I apply it globally, it works fine but as you said in vrf, is hard that's why I a trying to find out a way to do this under vrf.

I got it resolved by the following:

ip pim vrf test rp-address 1.1.1.1 test1

ip pim vrf test rp-address 2.2.2.2 test2

now one VRF has joined to two different RPs

access-list test1

permit 239.1.1.1

access-list test2

permit 239.1.1.2
