Matt,
My study partner and I could not find this documented anywhere. You didn't
miss anything. Our take on this was that Cisco's developers assumed that
sync is an antiquated feature. Hence, all their testing was done with sync
turned off. But Padhu is correct, if you make this an actual logical
full-mesh things will work. RRs are not logical full-meshes; they are
*simulated* full-meshes.
Hope that helps,
Daniel

The best way to confirm this is to make a full IBGP mesh. You will see that
it works.
Logical mesh using confederations and reflectors invalidate the sync
rule.This is my
observation.

Daniel,
That is exactly what I am seeing with my route reflector. I have three
routers peered with it, 2 of which are EBGP speakers.

My BGP stuff doesn't make it past the RR unless I turn off syncronization.
I get that "no valid path" crap even though I can see the next hop in my
routing table and ping it. Have you figured out why? Did I miss the part
of the documentation that says that reflectors don't work with
synchronization?

Yes, I get this with RRs when I left synchronization enabled.

Has anyone had a situation where BGP says "no valid path" but you have the
next hop in your routing table and you can ping it? What did you do? The
configs are long, so I won't post them. Just wandered if it rings a bell
with anyone...
