Verifying the configuration

1. Verify the LB function:

When the CC function detects a link fault, use the LB function to locate the fault.

# Enable LB on Router A to check the status of the link between MEP 1001 and MEP 5001 in

service instance 1.

[RouterA] cfd loopback service-instance 1 mep 1001 target-mep 5001

Loopback to 0010-FC00-6515 with the sequence number start from 1001-43404:

After the whole network status is obtained with the CC function, use the LT function to identify the

paths between source and target MEPs, and to locate faults.

2. Verify the LT function:

# Identify the path between MEP 1001 and MEP 5001 in service instance 1 on Router A.

[RouterA] cfd linktrace service-instance 1 mep 1001 target-mep 5001
