I was messing around today with the following....
Two routers in a network of about 7 or 8.
All routers running pim sparse-dense.
I setup each of the two as both Auto-RP announcers and mapping agents, using
an Anycast loopback (advertised into OSPF).
I setup MSDP between them and messed with costs in the network to ensure
that my source registered with one RP, and the two client listeners
registered with one RP each.
Apart from some oddities around caching, it all worked lovely - however, I
having trouble following through the possibilities of it all.
I didn't limit the scope of the AutoRP, but due to the anycast IP both
ignore the other (except through the MSDP which uses different IPs on the
routers).
I guess what I'm interested in exploring is how this could go wrong, as it
seems a nice neat way to deal with variable multicast situations - with
source and listeners always registering with the nearest RP. The
infrastructure seemed to deal very well with RP failure, but went horribly
wrong when MSDP was disrupted.
