Setting the optimal bypass tunnel selection interval
If you have specified multiple bypass tunnels for a primary CRLSP, MPLS TE selects an optimal bypass tunnel to protect the primary CRLSP. Sometimes, a bypass tunnel might become better than the current 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 set 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. Set the interval for selecting an optimal bypass tunnel. | fast-reroute timer interval | By default, the interval is 300 seconds. |
