If you keep a separate peering/loopback-IP for each peer, you can move individual peering sessions to other devices if needed. On Wed, August 27, 2008 05:39, Steve Bertrand wrote:

This wouldn't work for the loopback address you also use for iBGP or a physical interface.Ok. It probably would have made much more sense in my original post to clarify that each eBGP multihop peer session is configured on separate loopback interfaces, apart from the ones I use internally. Generally, I leave lo0 as-is, lo1 for internal, then configure each eBGP multihop peer on an incremental loopback basis thereafter. So, in essence, I'll continue to use a loopback (separate from internal functions) for ebgp-multihop peers, but instead of each session having its own interface/IP, I'll share one for all of them. Thanks everyone! Steve
