Jon,
I absolutely agree that the time has come to remove complex routing protocols from routers and use workstations.
Two points: 1. I am not sure whether BGP could be classified as a "complex routing protocol". 2. The proposed scheme does not remove BGP from the routers. In fact, BGP is used to communicate forwarding information between the routers and the route servers. So, if we're to assume that BGP is "a complex routing protocol", then using router servers does not allow "to remove complex routing protocols from routers". And if we're to assume that BGP is not a complex routing protocol, then we don't have a problem of removing "complex routing protocols from routers". So, it seems that using route servers would have no impact wrt to removing "complex routing protocols from routers". Yakov.
