It's not a fun process. I've given the matter quite a lot of thought. There are no easy ways to do this. Of course, with sufficient planning, some scripts, a good lab environment, and a few hours of downtime, a network can be transitioned. I don't recommend it for faint of heart. The best candidates for a BGP Confederation design are isolated eBGP networks (i.e. networks where AS border routers run eBGP, with no iBGP mesh) and greenfield networks. The last network I worked with that made a successful transition was Mindspring, AS4355, and they fell into the former category. The big question is, how big is the network. It's a trivial transition with 10 routers, lets say. If you have 100 fully meshed iBGP peers, I wouldn't bet on it. Also, implement communities - they make certain aspects of confederation configuration much easier. For more information on confeds, check on the NANOG web site. There are several archived presentations on the subject. - Dan Golding On Wed, 4 Oct 2000, ccie10 wrote: > > Is there an easy way to migrate an existing network running IBGP full mesh > to a > Condederation based configration.
