Parameters
setup-priority: Specifies the setup priority in the range of 0 to 7. A smaller number indicates a higher
priority.
hold-priority: Specifies the holding priority in the range of 0 to 7. A smaller number indicates a higher
priority. If you do not specify this argument, the holding priority is the same as the setup priority.
Usage guidelines
The setup priority and holding priority of an MPLS TE tunnel determines the importance of the tunnel. A
tunnel that has a higher setup priority than the holding priority of another tunnel can preempt the
resources of the second.
The setup priority and holding priority can be applied to the following scenarios:
• Multiple MPLS TE tunnels use the same path but the path does not have enough bandwidth for all
the tunnels. You can configure different setup and holding priorities for different tunnels to make
sure important tunnels can be established first.
• Before an important tunnel is established, multiple less-important MPLS TE tunnels have existed on
the network, occupying the bandwidth resources and the optimal path. You can assign a higher
setup priority to the import tunnel, so the tunnel can preempt the resources of the existing tunnels
and use the optimal path.
The setup priority of a tunnel must not be set higher than its holding priority, namely, the setup priority
value must be equal to or greater than the holding priority value.
Examples
# Set both the setup priority and holding priority of tunnel 0 to 1.
<Sysname> system-view
[Sysname] interface tunnel 0 mode mpls-te
