9.3.1 Before You Start

MPLS-TP OAM can be configured to monitor LSPs. Before you configure MPLS-TP OAM, an
LSP to be monitored must be created. Before configuring the MPLS-TP OAM monitoring
functions, familiarize yourself with the usage scenario, complete the pre-configuration tasks,
and obtain the data required for the configuration.
Applicable Environment
MPLS-TP has been widely used on transport networks. Since traditional transport networks,
such as SDH and OTN networks, set high benchmarks for reliability and maintenance, MPLS-
TP needs to provide powerful OAM capabilities.
MPLS-TP OAM can detect faults on bidirectional LSPs and collect performance statistics. On
the LSP shown in
MEP (RMEP), and the transit LERs are MIPs. MPLS-TP OAM runs on the MEPs and MIPs
and provide the functions listed in

Configuration Procedure
CC: checks the continuous connectivity
between the ingress LER and egress LER
of a bidirectional LSP. If a link fault is
detected, an alarm will be generated and the
link status will change to Down.
LB: checks the continuous connectivity
between the ingress LER and egress LER
of a bidirectional LSP based on
requirements. Check results will be directly
displayed on a terminal.
