Re: Anycast RP

Especially for Anycast RP you don't need BGP. The only thing Anycast RP
means is advertising a rendezvous point with an IP address that is
advertised by 2 or more routers. That way the router will use the rendezvous
point according to the RP that is close by according to IGP metric, could
also be advertised by BGP of course, but as long as the prefix is getting
advertised everything is fine.
What you are referring to is like Scott said MSDP. According to spec it's
needed, but it works as long as you get your RPF information exchanged,
either by static mroutes, an IGP or BGP. Though MSDP is designed to work
between Service Providers and thus an MBGP environment. It really depends on
your topology when used as a lab task.
