Continuity Check, Proactive Connectivity Verification, and Remote
Defect Indication functionalities are required for MPLS Transport
Profile (MPLS-TP) Operations, Administration, and Maintenance (OAM).

Continuity Check monitors a Label Switched Path for any loss of continuity
defect.  Connectivity Verification augments Continuity Check
in order to provide confirmation that the desired source is connected
to the desired sink.  Remote Defect Indication enables an end point to
report, to its associated end point, a fault or defect condition that
it detects on a pseudowire, Label Switched Path, or Section.

This document specifies specific extensions to Bidirectional
Forwarding Detection (BFD) and methods for
proactive Continuity Check, Continuity Verification, and Remote Defect
Indication for MPLS-TP pseudowires, Label Switched Paths, and Sections
using BFD as extended by this memo.  [STANDARDS-TRACK]
