Abstract
Systems and methods include receiving a pseudowire configuration for a pseudowire with a second network element; configuring the pseudowire as segment routing; adding the pseudowire configuration in link state advertisements (LSAs) that are flooding in a network via an interior gateway protocol (IGP); and maintaining a state of the pseudowire based on the flooding. The state is maintained without using label distribution protocol (LDP) or border gateway protocol-auto discovery (BGP-AD).
