Re: BGP and aggregation

BGP will discard any prefix with its own AS in the path, for loop prevention. Hence, one half of the AS would still be unable to reach the other half. This is why a partitioned AS is a failure condition. A tunnel is a means to keep the AS nonpartitioned.

I was thinking of doing iBGP over my transit connections (with a couple of static routes so the iBGP works) AND over my inter-city circuit. Any reason why this won't work? -Ralph
