BGP Signaling for VPLS Overview

BGP multiprotocol extensions (MP-BGP) enable BGP to support IPv4 services such as BGP/MPLS VPNs, which are sometimes known as RFC 2547bis VPNs. VPLS with BGP signaling is actually a BGP-MPLS application that has much in common with BGP/MPLS VPNs.

The procedures for configuring BGP signaling for BGP/MPLS VPNs and for VPLS are similar except, for VPLS, you must configure both of the following BGP address families:

BGP can exchange information in a VPLS topology within these address families. Specifically, BGP builds a full mesh of label-switched paths (LSPs) among all of the VPLS instances on each of the PE routers participating in a particular VPLS domain.

See Configuring BGP Routing for information about configuring BGP routing. See Configuring BGP-MPLS Applications for information about configuring BGP/MPLS VPNs.
