Parameters
igp: Uses the IGP metric.
te: Uses the TE metric.
Usage guidelines
Each MPLS TE link has two metrics: IGP metric and TE metric. By using 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: Tunnel1 for voice traffic and Tunnel2 for video traffic. Configure
Tunnel1 to use IGP metrics for path selection, and configure Tunnel2 to use TE metrics for path selection.
As a result, the video traffic travels through the path that has larger bandwidth and the voice service
travels through the path that has lower delay.
If you specify a metric type for a tunnel by using this command in tunnel interface view, the tunnel uses
the specified metric type for path selection. Otherwise, the tunnel uses the metric type specified by the
path-metric-type command in MPLS TE view for path selection.
Examples
# Configure Tunnel 0 to use the IGP metric for path selection.
<Sysname> system-view
[Sysname] interface tunnel 0 mode mpls-te
[Sysname-Tunnel0] mpls te path-metric-type igp

mpls te priority
Use mpls te priority to configure a setup priority and a holding priority for an MPLS TE tunnel.
Use undo mpls te priority to restore the default.
Syntax
mpls te priority setup-priority [ hold-priority ]
undo mpls te priority
Default
The setup priority and the holding priority of an MPLS TE tunnel are both 7.
