Step Command Remarks
4. Return to system view. quit N/A
5. Enter MPLS TE tunnel interface
view.
interface tunnel tunnel-number
[ mode mpls-te ]
N/A
6. Specify the metric type for
path selection.
mpls te path-metric-type { igp | te }
By default, no link metric type is
specified and the one specified in
MPLS TE view is used.
Execute this command on the
ingress node of an MPLS TE tunnel.
7. Return to system view. quit N/A
8. Enter interface view.
interface interface-type
interface-number
N/A
9. Assign a TE metric to the link. mpls te metric value
By default, the link uses its IGP
metric as the TE metric.
This command is available on
every interface that the MPLS TE
tunnel traverses.
Configuring route pinning
When route pinning is enabled, MPLS TE tunnel reoptimization and automatic bandwidth adjustment are
not available.
Perform this task on the ingress node of an MPLS TE tunnel.
To configure route pinning:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter MPLS TE tunnel interface
view. interface tunnel tunnel-number
[ mode mpls-te ]
N/A
3. Enable route pinning. mpls te route-pinning
By default, route pinning is
disabled.
Configuring tunnel reoptimization
Tunnel reoptimization allows you to manually or dynamically trigger the ingress node to recalculate a
path. If the ingress node recalculates a better path, it creates a new CRLSP, switches the traffic from the
old CRLSP to the new CRLSP, and then deletes the old CRLSP.
Perform this task on the ingress node of an MPLS TE tunnel.
To configure tunnel reoptimization:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter MPLS TE tunnel interface
view.
interface tunnel tunnel-number
[ mode mpls-te ]
