The mpls te priority command configures the setup and holding priority values for an MPLS TE tunnel.
The undo mpls te priority command restores default priority values.
By default, both the setup and the holding priority values are 7.
| Parameter | Description | Value |
|---|---|---|
| setup-priority |
Specifies the setup priority value. |
The value is an integer ranging from 0 to 7. The smaller the value, the higher the priority. |
| hold-priority |
Specifies the holding priority value. |
The value is an integer ranging from 0 to 7. A holding priority value must be less than or equal to a setup priority value. The smaller the value, the higher the priority. The default value is the same as the configured setup priority value. |
Usage Scenario
The setup priority of a tunnel must be no higher than its hold priority. This means a setup priority value must be greater than or equal to a hold priority value.
You can specify the priority of a tunnel to release resources of low-priority LSPs when network resources are insufficient so that high-priority LSPs can be established. Bandwidth cannot be shared by tunnels with different priorities. If make-before-break (MBB) is used to change tunnel priorities, tunnels may fail to be established or preempt bandwidth of other tunnels. Therefore, break-before-make (BBM) is used for tunnel processing.
