Hmm, I confess I'd forgotten about that one (it was 2 years ago).  We had a
customer that only wanted to multipath over ibgp paths if they had the same
cluster-list length thus the patch to add a knob to do so.

They didn't have any issues though. I guess I still don't have my head
wrapped around the exact problem that is solved by exchanging the bestpath
rules used?
