Hi Steven,
You could use MSDP along with Anycast RP.
Each RP could have a loopback address of exactly the same IP Address and
this would be advertised as the RP Address for the particular group(s). Then
configure MSDP between these RPs and that should be it. (Ensure that the
address you are using as the RP address is advertised in your routing
process(es))
Your other routers should use the RP that is metrically closes to them from
a routing point of view and if the "closest" one fails, it will just use the
next "closest" RP.
Hope this helps,
Pete
