Hi Matthew,
The autorp listener allows you to configure just sparse-mode on your
interfaces while still allowing dense-mode distribution of the autorp groups
2240.1.39 and 224.0.1.40. Since you are still using dense mode to
distribute the RP mappings in this scenario, I don't think the nbma-mode can
be used to allow the mapping agent to be on a spoke. That is what the
theory tells me, but I have not specifically labbed up the autorp listener -
nbma-mode combination.
