VCCV

Virtual Circuit Connectivity Verification (VCCV) is an OAM feature for L2VPN. It verifies the
connectivity of PWs on the data plane. VCCV includes the following modes:
•
Manual mode—Use the ping mpls pw command to manually test the connectivity of a PW.
•
Auto mode—Configure BFD or Raw BFD to automatically test the connectivity of a PW.
For more information about VCCV, see
Compatibility information
Commands and descriptions for centralized devices apply to the following routers:
•
MSR1002-4/1003-8S.
•
MSR2003.
•

Commands and descriptions for distributed devices apply to MSR4060 and MSR4080 routers.
MPLS L2VPN configuration task list
To establish an MPLS L2VPN, you must perform the following tasks:
1. Configure an IGP to achieve IP connectivity within the backbone.
2. Configure basic MPLS, LDP, GRE, or MPLS TE to set up public tunnels across the backbone.
3. Configure MPLS L2VPN on the PEs, including setting up PWs, and binding ACs to PWs.
This chapter only describes MPLS L2VPN configurations on the PEs.
MPLS L2VPN configurations vary by scenario:
•
Remote connection—To create a remote connection, configure an AC, configure a PW in
cross-connect view or auto-discovery cross-connect view, and bind the AC to the PW in
cross-connect view or auto-discovery cross-connect view.
