I'm in a scenario where I have two routers, configured with two loopbacks, connected together via two links. I'm in the process of transitioning from one loopback to the other and I was wondering if there are any caveats to having two sessions up...one BGP session to the first lookback (existing), then another BGP session up to the second loopback (new).
I don't believe their should be any issues with this...and I don't see any documentation suggesting otherwise...just thought I'd ask to be certain :-)
I think you shouldn't have any problem in this migration to loop2 iBGP endpoints.
It should be better if iBGP next-hop = OSPF router-id it is more safe it will pass the sync test (if sync is not disabled).
Hope to help
