I have two PIM domains configured with Anycast RPs:
-------------
|R1 ----- R2| Anycast RP 1.1.1.1
-------------
\ /
\ /
\ /
\ /
R3
|
| BGP
|
R4
/ \
/ \
/ \
/ \
-------------
|R5 ----- R6| Anycast RP 2.2.2.2
-------------
RFC 4611 says that redundancy between mesh groups will cause a loop
(http://tools.ietf.org/html/rfc4611#section-3.3), so is there a way to run MSDP
with redundancy between these two domains? Should the Anycast RP mesh group be
extended out to the edge routers (R3/R4) and MSDP be setup there? What about
if I add another set of edge routers for a backup link?
Thanks,
James
