Hi. I have an oldie but a goodie... NY and Phil are interconnected via DS3. In Phil. the DS3 terminates on the SAME router as the INTERNET circuit!! In NY, there are two separate routers for redundant Internet links; both 45Mb. IF THE INTERNET TOTALLY GOES DOWN IN NYC, we want to route NYC users to Phil. Also, we would like to have "clients" who use services come IN via the Philly link - but that's a separate isses I believe. Finally, if the Internet goes down in Philly, we want to automatically route users in Philly to the NY Internet via the dedicated DS3. Is the best way to do this centered on "route reachability" in BGP??? Please help.
I have this problem too.
