Configuring a BGP VPLS Instance

Configuration prerequisites
Configuring IGP on the PEs and P devices to guarantee the IP connectivity of the MPLS backbone
Configuring MPLS basic capability for the MPLS backbone on the PEs and P devices
Configuring MPLS L2VPN
Configuration procedure
When creating a BGP VPLS instance, you must specify a globally unique name for the VPLS instance
and set the peer discovery mechanism to automatic configuration.
In L2VPN implementation, the Kompella mode uses extended BGP as the signaling protocol for
transferring VC information. Therefore, the BGP mode is also called the Kompella mode. When
configuring a VPLS instance in BGP mode, you must configure BGP as the signaling protocol to be
used.
Follow these steps to configure a BGP VPLS instance:
