MPLS Fault Management Operations, Administration, and Maintenance (OAM)
Abstract
This document specifies Operations, Administration, and Maintenance
(OAM) messages to indicate service disruptive conditions for MPLS-
based transport network Label Switched Paths. The notification
mechanism employs a generic method for a service disruptive condition
to be communicated to a Maintenance Entity Group End Point. This
document defines an MPLS OAM channel, along with messages to
communicate various types of service disruptive conditions.
