Title: PSEUDO-WIRE SIGNALING FRAMEWORK USING INTERIOR GATEWAY PROTOCOLS
Abstract:
A method is implemented by a first Provider Edge (PE) network device in a network to configure a pseudo-wire (PW) between the first PE network device and a second PE network device in the network using an Interior Gateway Protocol (IGP). The method includes receiving a first advertisement message flooded in the network by the second PE network device via the IGP, where the first advertisement message advertises the PW. The method further includes configuring a local forwarding information base with a local PW label associated with the PW such that the first PE network device forwards traffic encapsulated with the local PW label to an Attachment Circuit associated with the PW and flooding a second advertisement message in the network via the IGP that includes an indication that the first PE network device is ready to receive traffic from the second PE network device over the PW.
