VPLS – BGP Auto-discovery and Signaling
The VPLS control plane is used for auto-discovery and signaling. Auto-discovery involves locating all provider
edge (PE) devices that participate in a particular VPLS instance. Signaling is accomplished by configuring pseudo-
wires for a VPLS instance. In the past, LDP was used for signaling and BGP was used for auto-discovery (RFC
6074). Now, the VPLS BGP Signaling L2VPN feature supports RFC 4761 by simplifying the auto-discovery and
signaling of all known PE devices in a VPLS instance by using BGP for both functions.
