RE: Using BGP to force inbound and outbound routing through particular routes

There is nothing about a cable modem that would normally prevent a BGP session. Nor do all the intermediate routers need to support BGP (multi-hop BGP). However, direct connections are preferred.
Your _real_ challenge is convincing Roadrunner's NOC staff to program one of their backbone routers to do a BGP session with a cable modem sub. Or, for that matter, getting them to even route a non-roadrunner IP block to a cable modem sub.
Instead you might try borrowing a bunch of old 2500s and setting up a test lab that isn't connected to actual net.
Best of luck on your CCIE. John At 02:06 PM 11/2/2005, Edward W. Ray wrote:
