Managing active edge devices in VPLS using BGP signaling

摘要

In one embodiment, a method includes establishing in a Virtual Private Local Area Network (LAN) Service (VPLS) over Multi-Protocol Label Switching (MPLS) network a floating pseudowire between a first provider edge router and a redundancy group having a plurality of provider edge routers each configured to forward data toward a external device. Each provider edge router in the redundancy group is configured to maintain an active link to the external device. A provider edge router that is not a member of the redundancy group sends data directed to the external device through the floating pseudowire. Only one provider edge router in the redundancy group receives and forwards the particular data to the external device.

1. A method comprising:
establishing a floating pseudowire between a first provider edge router and a redundancy group comprised of a plurality of provider edge routers, wherein each provider edge router in the redundancy group is configured to forward data toward an external device and is configured to maintain a direct active link to the external device; the first provider edge router sending particular data directed to the external device through the floating pseudowire to the redundancy group; wherein only one provider edge router in the redundancy group is configured to forward the particular data through one of direct active links to the external device.
