Inter-domain multi-segment PW
An inter-domain multi-segment PW has concatenated PWs in different ASs, and is a method for
inter-AS option B networking.
As shown in
different ASs, you can perform the following operations:
•
Concatenate PW 1 and PW 2 on ASBR 1.
•
Concatenate PW 2 and PW 3 on ASBR 2.

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.
