multicast mvrf design question

Answered Question
Aug 20th, 2011

Hello everyone!

I got a task to implement multicast traffic throug different vrfs in existing network topology.

There is 2 vrfs: server and pc. The work separatelly, but there is a router r2 (central site), where vrfs server and pc are merged in additional vrf common (central vrf). Also, 2 route reflectors are in this topology, so all other routers are route-reflector clients of both route-reflectors. All interfaces are in sparse-dense mode, multicast and vrf multicast has already enabled as well as mdt relatonships with route-reflectors.

Now it works well using unicast, but I need to change this traffic to a multicast one.

I can't change neigher topology nor vrf import/export configuration. I am hesitating about is it possible to make multicast traffic flows between vrf's in this situation.

Green lines are described server vrf (ip vrf server)

Red lines are described pc vrf (ip vrf pc)

Black lines are described mpls lines (mpls ip)

At least multicast flows shoud work as described using blue lines

Please, give some advices about best solution to my issue:

1) how to plan mdt domains

2) how to plan pim exchange

3) may be some else

I don't know what information I can give more in this case, so it could be provided on demand.

Thank you.
