The Virtual Circuit Connectivity Verification (VCCV) protocol
specified in RFC 5085 provides a control channel (CC) that is
associated with a pseudowire (PW). This document specifies an
additional VCCV control channel type to be used with pseudowires that
do not use the PW Control Word and that are carried over an MPLS
network. This new VCCV CC type uses the Generic Associated Channel
Label defined in RFC 5586 to distinguish VCCV packets from packets
carrying user data. This new VCCV CC type introduces compatibility
with the method of MPLS Label Switched Path Operations,
Administration, and Maintenance (OAM) identification, particularly in
MPLS Transport Profile (MPLS-TP) networks (RFC 5921).
This document is a product of the Pseudowire And LDP-enabled Services Working Group of the IETF.
This is now a Proposed Standard.
