You can use the candidate RP priority in BSR to choose the highest and have
multiple ip addresses. You can also have redundancy with AutoRP, but there
is no priority switch. Highest loopback address wins, if a loopback isn't
present, then highest ip address wins. When your talking about MSDP, your
talking about anycast RP, which is when two RP's share the same loopback
address for an RP identifier, and that network is routed throughout the
domain as a /32 host route, therefore the devices contact RP's contact the
closet RP. MSDP is then used to propogate the Registration/Receiver messages
to the other RP in the form of MSDP SA messages.
