Probably what you have in mind is RFC 3446:
"Anycast Rendevous Point (RP) mechanism using Protocol Independent
Multicast (PIM) and Multicast Source Discovery Protocol (MSDP)".

This solution eventually requires minor (if any) additional
coding/changes (if you have PIM-SM and MSDP implemented of course).

What I had in mind with regard to Anycast RP is RFC 4610:
"Anycast-RP Using Protocol Independent Multicast (PIM)".
This solution requires changes to the PIM-SM implementation itself,
but does not need/use MSDP.
