Abstract:
1. A method for recovering network routing in a communication network, comprising: switching network service from a first network element (“NE”) to a backup NE in response to an earlier device failure associated with the first NE; recovering the first NE from the earlier device failure; establishing a first link configured to transmit data packets between the first NE and a network device after the first NE is recovered from the device failure; initiating a discovery process utilizing network reachability protocol to identify a plurality of routing paths associated with the first NE while network communication between the network device and a second NE is facilitated by the backup NE; updating a routing table in the first NE in accordance with the plurality of routing paths; and issuing a ready message from the first NE to the network device indicating reverting network service from the backup NE to the first NE when the routing table contains at least a portion of completed routing information.
