MPLS L2VPN configurations vary with the following scenarios:

MPLS L2VPN connection—To create an MPLS L2VPN connection, configure an AC, configure a PW
in cross-connect view or auto-discovery cross-connect view, and bind the AC with the PW in

cross-connect view or auto-discovery cross-connect view.

Multi-segment PW—To create a multi-segment PW, configure two PWs and bind the two PWs in

cross-connect view.

Enabling L2VPN

Perform this task to enable L2VPN so the PE can support MPLS L2VPN.
Before you perform this task, configure an LSR ID for the PE with the mpls lsr-id command, and enable

MPLS with the mpls enable command on the backbone interface of the PE. For more information about

these commands, see MPLS Command Reference.
To enable L2VPN:

Configuring an AC

The PE connects to a CE through a Layer 2 Ethernet interface. Configure a service instance on the Layer

2 Ethernet interface to match specific packets from the AC.
