mpls te reoptimization (tunnel interface view)
Use mpls te reoptimization to enable tunnel reoptimization.
Use undo mpls te reoptimization to disable tunnel reoptimization.
Syntax
mpls te reoptimization [ frequency seconds ]
undo mpls te reoptimization
Default
Tunnel reoptimization is disabled.
Views
Tunnel interface view
Predefined user roles
network-admin
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 feature to implement dynamic CRLSP optimization. For example, if a link on the optimal path does not have enough reservable bandwidth during tunnel setup, 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 is mutually exclusive with the following commands:
mpls te route-pinning.
mpls te backup.
If both the mpls te reoptimization and mpls te bidirectional commands are configured, only the mpls te bidirectional command takes effect.
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
