Configuration Guide - Reliability
LM can be used to collect packet loss statistics and evaluate link performance. LM is one of the
performance monitoring functions provided by MPLS-TP. It includes single-ended LM and
dual-ended LM.
The section uses the configuration of dual-ended LM as an example. The configuration of single-ended LM is
the same as that of dual-ended LM except the configuration for querying packet loss statistics.
As shown in
The following deployment is performed to ensure the connectivity between LSRA and LSRC:

Procedure
Step 1 Configure a bidirectional LSP.
For details about how to configure a bidirectional LSP between T-PEs, see "Configuring a Static
Bidirectional LSP" in the HUAWEI NetEngine80E/40E Router Configuration Guide-MPLS or
information in the configuration files of this configuration example.
Step 2 Create an ME and bind it to a bidirectional LSP.
# Create an ME named test on LSRA and bind the ME to Tunnel 1/0/0.

NOTE
Figure 10-7, LSRA, LSRB, and LSRC are connected using a bidirectional LSP.
LSRA and LSRC serve as MEPs.
LSRB serves as a MIP.
