I must own up to being slightly rhetorical here; RFC 4610 describes 
using PIM for RP-RP sync, and we in fact use that on JunOS to implement 
anycast RP without MSDP.

I guess the real question is, is there a PIM6 version of 4610, and is it 
widely supported. I know JunOS has it, and docs suggest NX-OS does, but 
not sure about IOS, and not sure about any of them for IPv6.
