BGP Auto-Discovery feature enables the automatic discovery of VPLS peers, eliminating the need for manual peer configuration. Once peers are discovered, pseudo-wires (PWs) are established between them using LDP signaling, there by simplifying and streamlining the VPLS setup process.

For more details, refer to the BGP Auto-Discovery (AD) for LDP VPLS section in the OcNOS Multi-Protocol Label Switching Guide, Release 6.6.0.
