In the process of establishing a CR-LSP, if no path with the required bandwidth exists, you can perform bandwidth preemption according to setup priorities and holding priorities.
Perform the following configurations on the ingress node of an MPLS TE tunnel.
The system view is displayed.
The tunnel interface view of the MPLS TE tunnel is displayed.
The priority for the tunnel is configured.
Both the setup priority and the holding priority range from 0 to 7. The smaller the value is, the higher the priority is.
By default, both the setup priority and the holding priority are 7. If only the setup priority value is set, the holding priority value is the same as the setup priority value.
The setup priority should not be higher than the holding priority. So the value of the setup priority must not be less than that of the holding priority.
The current tunnel configuration is committed.
