## AI overview

This article examines IBGP-only data center networks as an alternative to EBGP-only designs. It explains the need for directly connected IBGP sessions, route reflectors, and next-hop changes, noting that the approach works but violates an RFC SHOULD NOT recommendation and may not be supported by some implementations.

## Source excerpt

Whenever I was explaining how one could build EBGP-only data center fabrics, someone would inevitably ask, "But could you do that with IBGP?" TL&DR: Of course, but that does not mean you should. Anyway, leaving behind the land of sane designs, let's trot down the rabbit trail of IBGP-only networks. Read more ...
