10.3.4 (Optional) Configuring LB (to Be Performed at a Specified
Time) for a PW
LB is the most common tool used to detect connectivity of MPLS-TP links.
Context
LB can monitor the connectivity between two MEPs or between a MEP and a MIP. Unlike CC
or CV that is performed periodically, LB is performed at a specified time.
The ping meg command can be run to trigger LB, and LB packets are used to check the following
items:
l

Procedure
Step 1 Run:
ping meg
LB is enabled to monitor the connectivity of an MPLS-TP link.
If the network speed is rather slow, timeout-value (a parameter that specifies the period for waiting for a response
packet) can be set to a larger value when the ping meg command is configured.

cc exp exp-value command to configure the priority of CCMs.
If the MPLS-TP network is severely congested and the priority of CCMs is low, CCMs cannot
be sent. Therefore, a proper priority needs to be configured for CCMs based on network
conditions.
On the MEP, run:
cc send enable
Sending CC/CV packets is enabled on the MEP.
On the RMEP, run:
cc send enable
Sending CC/CV packets is enabled on the RMEP.
On the MEP, run:
cc receive enable
Receiving CC/CV packets is enabled on the MEP.
On the RMEP, run: cc receive enable
Receiving CC/CV packets is enabled on the RMEP.
