Configuring the metric type for path selection
Each MPLS TE link has two metrics: IGP metric and TE metric. By planning the two metrics, you can select
different tunnels for different classes of traffic. For example, use the IGP metric to represent a link delay
(a smaller IGP metric value indicates a lower link delay), and use the TE metric to represent a link
bandwidth value (a smaller TE metric value indicates a bigger link bandwidth value).
You can establish two MPLS TE tunnels: Tunnel 1 for voice traffic and Tunnel 2 for video traffic. Configure
Tunnel 1 to use IGP metrics for path selection, and configure Tunnel 2 to use TE metrics for path selection.
As a result, the video service (with larger traffic) travels through the path that has larger bandwidth, and
the voice traffic travels through the path that has lower delay.
To configure the metric type for tunnel path selection:
Step
1. Enter system view.
2. Enter MPLS TE view.
3. Specify the metric type to use
when no metric type is
explicitly configured for a
tunnel.
4. Return to system view.
5. Enter MPLS TE tunnel interface
view.
6. Specify the metric type for path
selection.
7. Return to system view.
8. Enter interface view.
9. Assign a TE metric to the link.
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
1. Enter system view.
Command
system-view
mpls te
path-metric-type { igp | te }
quit
interface tunnel tunnel-number
[ mode mpls-te ]
mpls te path-metric-type { igp | te }
quit
interface interface-type
interface-number
mpls te metric value

Remarks
N/A
N/A
By default, a tunnel uses the TE
metric for path selection.
Execute this command on the
ingress node of an MPLS TE tunnel.
N/A
N/A
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.
N/A
N/A
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.
