I've been doing a lot of searching on this and can't seem to find any helpful information. I've read the CLI configuration guides and they don't really tell me what I need to know. My situation: I have a Nexus 9500 that is a BSR and C-RP. It is the only device in the network that has rp-announce configured. Upstream will be an ASA 5516-X that has multicast enabled with PIM/IGMP enabled on inside and outside interfaces. ACLs are in place to allow the traffic to flow. Outside is an ASR1001 that has mGRE to a few other sites.
nx9504 <-> ASA <-> ASR <-> mGRE to other sites.
My question is whether the the ASR will learn through the ASA about the Nexus being an RP (the only one that is announcing) or if the ASA has to have some other configuration in place for the ASR to learn? Again, I've read the CLI guide and it doesn't give the answer.
