mpls te path-metric-type
Use mpls te path-metric-type to specify the link metric type for a tunnel.
Use undo mpls te path-metric-type to restore the default.
Syntax
mpls te path-metric-type igp
undo mpls te path-metric-type
Default
No link metric type is specified for path selection of a tunnel.
Views
Tunnel interface view
Predefined user roles
network-admin
Parameters
igp: Uses the IGP metric.
Usage guidelines
Each MPLS TE link has a metric. The IGP metric represents a link delay (a smaller IGP metric value
indicates a lower link delay). By using the IGP metric for MPLS TE links, you can make sure delay-sensitive
traffic such as voice traffic 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.
