Yes. In fact, that's *required* if you want to do multi-path.
I seem to do multi-path just fine with maximum-paths ibgp 2 on my
RR clients inside a VRF that sees a default sourced from two
different RRs. Said VRF has a common RD between the two PEs.
How is that different?
Well, AIUI multipath *ought* to require unique RDs. Obviously not;
I wonder how that's working for you?
So based on the link you posted previously, which I am currently
making my way through, what's happening is on my production network
where this multi-path stuff is actually working, I'm using XR as my
RRs, which has add-path support.
Presumably the RR clients have add-path too (it's needed at both ends)?
Other explanations might be that by chance one RR had advertised one
path and the other RR another path.
But yes, my original email should have been more specific: unless you
have add-paths, unique RD is required for multipath.
