optimal bypass tunnel because, for example, the reservable bandwidth changes. Therefore, MPLS TE
needs to poll the bypass tunnels periodically to update the optimal bypass tunnel.
Perform this task on the PLR to configure the interval for selecting an optimal bypass tunnel:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter MPLS TE view. mpls te N/A
3. Configure the interval for
selecting an optimal bypass
tunnel.

By default, the interval is 300
seconds.
