The problem you reference is expected (i.e. if the Mapping Agent is at a
spoke, but the Candidate RP is at the hub). There is no way that the
advertisements can "transcend" the hub to the other spokes without a tunnel
or fully-meshed VC of some sort (only one of which, in this case, contains a
Mapping Agent). Again - move the 'send-rp-discovery' (Mapping Agent) to the
hub, leave the 'send-rp-announce' (Candidate RP) on the spoke...

I've had problems when I only use one mapping agent...If I configure a hub
and spoke where the hub is the RP and a spoke is the MA, I've found that the
other spokes often don't learn about the RP....I'll try it again to verify
this.
