Troubleshooting Tunnel Selection: Example
You can use the debug mpls l2transport vc event command to troubleshoot tunnel selection. For
example, if the tunnel interface that is used for the preferred path is shut down, the default path is
enabled. The debug mpls l2transport vc event command provides the following output:
