Here's a related question. Suppose provider A has a customer C who multihomes with a connection to A and provider B. C uses IP's assigned by A. C terminates service with A...but keeps announcing A's space to B. B propogates the routes to their peers. B and C ignore requests that they stop using A's space and renumber into B's. How does A reclaim their space?
One obvious solution is dueling routes...A could announce more specific routes, fouling things up for B and C hoping this will serve as encouragement for C to renumber.
And then C could announce more specific routes, and so forth, although you'll run into filters and start being ignored at some point. That's really the sort of problem better resolved by lawyers than by engineers. -Steve -------------------------------------------------------------------------------- Steve Gibbard scg@gibbard.org
