Larry,
Cisco routers will prefer Auto-RP advertisements over static RP
assignments. In order to prevent rouge auto-RP assignments, configure
the 'ip pim accept-rp' command to specify which static RPs and
corresponding groups you will send join messages to. The 'ip pim
accept-rp auto-rp' will instruct the router to ignore all static RP
assignments and only allow auto-RPs.
HTH,

I think it can be configure in MA to chose which rp to advertise to rest
of
the network when he get more then one rp for the same group.
