26.4.3 Configuring link tracking function
By configuring the link tracking function, the path between the specified maintenance
endpoint and the destination maintenance endpoint can be found, thus the link failure can be
realized
Location。 It includes the following two functions：
Find the path from the specified maintenance endpoint to the destination maintenance
endpoint: by sending the LTM message from the designated maintenance endpoint to the
destination maintenance endpoint, and detecting the LTR message of the response to
determine the path between the devices。
Automatic transmission link tracking message: enable this function, while maintaining
at the end of 3.5 CCM packet sending period has not received the message sent to the
remote maintenance of CCM endpoint, which determine the same remote maintenance
error connecting terminals, will send the LTM message LTM message (target for remote
maintenance endpoints, TTL field of LTM message for a maximum of 255), through the
LTR message response to locate fault detection。

<instance-id> mep <mep-id>
{target-mep <target-mep-id> |
