4000 Router Series MPLS Command Reference

Parameters

frequency seconds: Specifies the tunnel reoptimization frequency in the range of 1 to 604800 seconds.

The default is 3600 seconds.

Usage guidelines

MPLS TE uses the tunnel reoptimization function to implement dynamic CRLSP optimization. For example,

when MPLS TE sets up a tunnel, if a link on the optimal path does not have enough reservable bandwidth,

MPLS TE sets up the tunnel on another path. When the link has enough bandwidth, tunnel optimization

can automatically switch the tunnel to the optimal path.

You can configure the ingress to perform tunnel reoptimization periodically, or you can use the mpls te

reoptimization command in user view to trigger the ingress to perform a tunnel reoptimization at any

time.

On the same tunnel interface, the mpls te reoptimization command cannot be used together with these

commands: mpls te auto-bandwidth adjustment, mpls te route-pinning, mpls te backup, and mpls te

resv-style ff.

Examples

# Enable reoptimization for tunnel 0, and set the reoptimization frequency to 43200 seconds (12 hours).

<Sysname> system-view

[Sysname] interface tunnel 0 mode mpls-te

[Sysname-Tunnel0] mpls te reoptimization frequency 43200

Syntax

Views

Predefined user roles

Usage guidelines

After reoptimization is enabled for a tunnel by using the mpls te reoptimization command in tunnel

interface view, you can use the mpls te reoptimization command in user view to trigger the ingress node

to immediately reselect an optimal path for the tunnel.

Examples

# Reoptimize all reoptimization-enabled MPLS TE tunnels.
