Minimum Configuration for BGP Autodiscovery with LDP Signaling
This example illustrates the minimum L2VPN configuration required for BGP Autodiscovery with LDP
Signaling, where any parameter that has a default value is not configured.
(config)# l2vpn
(config-l2vpn)# bridge group {bridge group name}
(config-l2vpn-bg)# bridge-domain {bridge domain name}
(config-l2vpn-bg-bd)# vfi {vfi name}
