(Optional) Configuring Auto Bypass Tunnel Re-Optimization
Auto bypass tunnel re-optimization allows paths to be recalculated at certain intervals for an auto bypass tunnel. If an optimal path is recalculated, a new auto bypass tunnel will be set up over this optimal path. In this manner, network resources are optimized.
Context
Network changes often cause the changes in optimal paths. Auto bypass tunnel re-optimization allows the system to re-optimize an auto bypass tunnel if an optimal path to the same destination is found due to some reasons, such as the changes in the cost. In this manner, network resources are optimized.
This configuration task is invalid for LSPs in the FRR-in-use state.
Procedure
- Run system-view
The system view is displayed.
- Run mpls
The MPLS view is displayed.
- Run mpls te auto-frr reoptimization [ frequency interval ]
Auto bypass tunnel re-optimization is enabled.
- (Optional) Run return
Return to the user view.
- (Optional) Run mpls te reoptimization [ auto-tunnel name tunnel-interface | tunnel tunnel-number ]
Manual re-optimization is enabled.
After you configure the automatic re-optimization in the MPLS view, you can return to the user view and run the mpls te reoptimization command to immediately re-optimize the tunnels on which the automatic re-optimization is enabled. After you perform the manual re-optimization, the timer of the automatic re-optimization is reset and counts again.
- Run commit
The configurations are committed.
