Another possibility could be that the RP is statically configured on the multicast network, while the RTA router is not statically configured with the RP.

That could definitely be a reason. If the RP elected by RTA is not RTB, then RIB won't be able to see the multicast source.

What about the possibility that the RP elected by RTA is not RTB?

I agree with you, Yvonne. If RTB fails the RPF check of the source, RIB won't be able to see the multicast source.

I think the reason why RIB cannot see the multicast source is because there is no unicast route from RTB to RTA.

It could be a possibility. If RTA and RTB are not correctly synchronized in terms of RP, it could lead to issues with multicast routing.

But what if the RP elected by RTA is not RTB? Could that also be a reason?

Yes, that makes sense. If there is no unicast route from RTB to RTA, it could cause problems.

I think the issue could be related to the RPF check failing on RTB.
