  • Handling switchover of multi-homed connections in VPLS networks
    Patent number: 8780699
    Abstract: A method includes establishing a bi-directional pseudowire (BPW) between a first provider edge (PE) router and a second PE router that are forwarders for a multi-homed VPLS customer site associated with a VPLS domain. The first PE router has a designated forwarder status and the second PE router has a backup forwarder status relative to the VPLS customer site. The BPW is established as an auxiliary standby BPW external to the VPLS domain. The method also includes detecting a change in topology of the network with the first PE router, wherein the change in topology affects connectivity by the first PE router to the VPLS customer site associated with the VPLS domain, and, upon detecting the change in topology, utilizing the BPW as an active interface within the VPLS domain for forwarding network traffic to the VPLS customer site.
