<p>Distance vector routing protocols such as the Routing Information Protocol fail to rapidly reconfigure to use redundant links. By modifying the outgoing advertised hop count (31) upon detecting a failure in a connection (32) for which a backup or redundant connection exists, incoming traffic is diverted to the redundant or backup connection (33). An artificially high hop count (31) is advertised for a given port, and when a failure or loss of reachability occurs in a connection associated with that port (32), an advertisement of a lower hop count on the backup or redundant connection for the given port is triggered (33). This causes rapid rerouting of incoming traffic to the backup or redundant connection.</p> |
