Re: Distributed Router Fabrics

In a distributed fabric, where is the traditional control plane run? Say I've got 100 BGP sessions of upstream,peer, and downstream across ten routers. Is each pizza box grinding this out on its own, or is the work done on the x86 box mentioned in the larger installations?

one way to think of it is that each pizza box (customer facing ports) recognizes control plane messages (e.g. port 179) and "punts" them to the control plane box, aka routing engine. randy
