For simplicity, assume that destinations in this problem are domains, not prefixes. Recall that routes are expressed in terms of the series of domains: e.g., [A-B-C] denotes a route that started with domain A and went to domain B and then to domain C (which is the destination). Domains always advertise the route to themselves (i.e., domain X advertises the path [X] to all peers, customers, and providers). The following connectivity/business relationships exist: B is a customer of A C is a customer of A D is a customer of B E is a customer of B F is a customer of C G is a customer of C B and C are peers E and F are peers Assuming that each domain's routing policies follow normal business practice, and that BGP has converged, What routes does A advertise to B? _ [A] [A-C] [A-C-F] [A-C-G] 9 What routes does C advertise to B? _[C] [C-F] [C-G] What routes does E advertise to B? _[E] What routes does F advertise to E? ___[F]___ What path do packets from E take to F? __E-F__ What path do packets from D take to F? ___D-B-C-F___ What path do packets from D take to G? ___D-B-C-G 10...
