Hello,
I have a quick question with using Inter-VRF multicast with ACI. We have a multicast application that is outside of our ACI fabric. The Receiver is within the ACI Fabric. The L3out to the larger network is associated with a VRF (BLUE VRF) and leaks unicast routes to the RED VRF where the multicast receiver lives. the PIM rendezvous point is also outside the ACI fabric.
When the multicast receiver subscribes to the group, I don't see any (*, G) info outside the RED VRF. When I set up a receiver in the ACI BLUE VRF, everything works fine.
We tried setting up inter-vrf multicast in both RED and BLUE VRFs but that broke all multicast in the ACI fabric. We searched the internet for info on how the Inter-VRF multicast option works, but didn't find anything useful just some guidelines and limitations. I think we are within the guidelines in our scenario.
I was hoping someone in the community has some tips for guidance on how to properly use the Inter-VRF multicast feature. We broke the network once and folks weren't happy, so we want to be more careful next go.
Seeing how the source and the RP are on the side of the BLUE VRF, should we implement the Inter-VRF multicast in the BLUE VRF or does the configuration go on the receiver's side RED VRF?
