The configurations of an MPLS TE tunnel can only take effect after the mpls te commit command is run. The destination and tunnel ID must be configured; otherwise, the commitment fails, and you need to configure both of them and then commit the configuration again. If the MPLS TE configuration changes, you must run the mpls te commit command to validate the modification.
Each time the MPLS TE tunnel configuration is changed, the mpls te commit command must be run to make the modification take effect. If this command is not run, the changed configuration can be saved in the configuration file but cannot take effect.
