The device may monitor control channels associated with physical interfaces, where each physical interface is associated with a separate control channel and pseudowires that are associated with virtual local area networks (VLANs). The device may detect an interruption in service over a first control channel associated with a first physical interface, and determine whether an impending event will occur at a first provider edge device associated with the first physical interface. Routing metrics may be adjusted for each VLAN associated with the first physical interface, in order to route ingress traffic away from the first provider edge device and towards another device associated with a different physical interface. The device may reroute traffic to at least one remote customer edge device over a pseudowire associated with the second provider edge device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pseudowire control channel for signaling events","description":"A client edge device relying upon end-to-end pseudowire connections may compensate for network interruptions due to impending events.
