Hi
We have a bridge domain which is layer 2 for now. It is enabled for multicast with default igmp policy associated.
I can see igmp snooping is turned on and not many multicast groups are learnt. The multicast querier is external to the fabric and reachable via layer 2 through the border leaf switches.
We want to enable optimised multicast flood(OMF)for the bridge domain. I have some queries around this:
1. Would OMF work properly with external multicast querier?
2. If I configure the BD subnte can that be used as a multicast querier?
3. If I have to configure multicast querier on the switch, do i have to configure separate querier on every leaf switch or an anycast IP(i just configure 1 querier across the entire aci fabric)? I have nearly about 25 switches in each pod. 2 such pods in our environment.
Any other design tips.
Thanks
Rohan
