Disregard last e-mail. Lack of caffeine told me R1 was the RR. It's not.

>R2< will have the notes below.

R1, an RR client will only have ONE path.

That will depend on what you have configured (multipath or not?), but in a
generic configuration you'll get one "best" path showing up on R1.

"sh ip bgp" should indicate to you that there is more than one valid path,
but only one best path.

"sh ip ro b" will verify your routing table.
