Hi there, everyone!
This post explains how to configure BGP AD VPLS. Please see more details below.
BACKGROUND INFORMATION
BGP AD VPLS, short for Border Gateway Protocol Auto-Discovery virtual private LAN service, is a new technology for automatically deploying VPLS services.
BGP AD VPLS has the advantages of both Kompella and Martini VPLS. BGP AD VPLS automatically discovers VPLS BGP peers, simplifying the configurations and saving labels.
BGP AD VPLS-enabled devices exchange extended BGP Update packets carrying VSI member information to automatically discover BGP peers in a VPLS domain. After BGP peer relationships are established, these devices use LDP Mapping (FEC 129) messages to negotiate and establish VPLS PWs. VPLS services are automatically deployed after PWs are established.
BGP AD VPLS configuration VPLS tunnel is mainly divided into two steps.
AUTOMATICALLY DISCOVERING PEs IN A VPLS DOMAIN
Automatically discovering PEs in a VPLS domain is the first phase of VPLS service deployment. BGP is used to automatically discover PEs in a VPLS domain.
AUTOMATICALLY ESTABLISHING A PW
After a PE discovers a remote PE in the same VPLS domain, the two PEs use LDP Mapping (FEC 129) messages to negotiate PW establishment.
Automatic VPLS member discovery and PW establishment simplify the configurations required by VPLS networks, enable automatic service deployment, and reduce OPEX for carriers.
In this project, the PE device support to configure the BGP AD VPLS.
Before configuring BGP AD VPLS, complete the following tasks:
configure IP addresses and routes on PEs and Ps to ensure that neighboring nodes are reachable at the network layer. In this project, the customer deploys a route reflector. The PE device only needs to configure neighbors with RR under the L2VPN address family;
configure LSR IDs and enable basic MPLS functions on PEs and Ps;
establish tunnels between PEs to bear L2VPN services;
enable MPLS L2VPN on PEs.
The configuration template is as per below pictogram.
Table 1-1. BGP AD VSI configuration example

This would be all on how to configure BGP AD VPLS. Thanks for reading this post!
