Brian,

I think you're missing the point - in the situation you are describing -
isolated pops with small netblocks, there is no reason to run iBGP at
all. Running eBGP in an isolated configuration works fine. Sharing routing
information between your routers with iBGP is of limited utility when you
don't have leased lines to backhaul the traffic across.

Send 'unsubscribe' in the body to 'list-request@inet-access.net' to leave.
