Hi Davis,
I’m afraid not. The AutoRP addresses 224.0.1.39 and 224.0.1.40 are using dense mode flooding and this is not supported by NBMA mode. If your mapping agent is behind a spoke router then you’ll have to pick one of the three options to fix this:
- Get rid of the point-to-multipoint interfaces and use sub-interfaces. This will allow the hub router to forward multicast to all spoke routers since we are using different interfaces to send and receive traffic.
- Move the mapping agent to a router above the hub router, make sure it's not behind a spoke router.
- Create a tunnel between the spoke routers so that they can learn directly from each other.
