R0106-HP MSR Router Series MPLS Command Reference(V7)

133
Parameters
label: Enables both route recording and label recording. If you do not specify this keyword, this
command enables only route recording.
Usage guidelines
Route recording records the nodes that an MPLS TE tunnel traverses. Label recording records the label
assigned by each node. The recorded information helps you know about the path used by the MPLS TE
tunnel and the label distribution information, and when the tunnel fails, it helps you locate the fault.
Examples
# Enable route recording for MPLS TE tunnel 0.
<Sysname> system-view
[Sysname] interface tunnel 0 mode mpls-te
[Sysname-Tunnel0] mpls te record-route

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
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 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.
