Technique to minimize traffic loss on a router reload/restart
Abstract:
A link state information correction scheme is implemented by the present disclosure. In one embodiment, the correction scheme is implemented by a reload logic module that cooperates with link state protocol logic configured on a reload routing element (or routing element that has reloaded or hard restarted). The reload logic module is configured to receive a database descriptor message at a reload routing element, where the database descriptor message is received from a neighbor routing element during an adjacency formation. The reload logic module is also configured to determine whether the database descriptor message identifies a stale version of a link state advertisement (LSA), where the LSA is self-originated by the reload routing element. The reload logic module is also configured to generate a new version of the LSA during the adjacency formation.
