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 upon detecting a failure in a connection for which a backup or redundant connection exists, incoming traffic is diverted to the redundant or backup connection. An artificially high hop count is advertised for a given port, and when a failure or loss of reachability occurs in a connection associated with that port, an advertisement of a lower hop count on the backup or redundant connection for the given port is triggered. This causes rapid rerouting of incoming traffic to the backup or redundant connection.
