It should work. I have topology similar to yours and hub and spoke can both
ping the group address on the other spoke. Hub is the RP and the mapping
agent.
I don't think you need auto-rp listener because the spoke are directly
connected to the hub. If you had another level of up/downstream routers you
would need it.
can you post configs?
