However, in the present form, this mechanism is inadequate to verify connectivity of a segment of a Multi-Segment PseudoWire (MS-PW) from any node on the path of the MS-PW. Similar shortcoming is seen on a bidirectional co- routed MPLS TP LSPs. This document defines a TLV to address these shortcomings.
