mpls te igp metric { absolute value | relative value }

Tunnel interface view

absolute value: Assigns an absolute metric to the TE tunnel for path calculation. 
The value argument takes an integer in the range 1 to 65535. This value is directly 
used for path calculation.

relative value: Assigns a relative metric to the TE tunnel for path calculation. The 
value argument takes an integer in the range -10 to +10. The default is 0. The cost 
of the corresponding IGP path must be added to this relative metric before it can 
be used for path calculation.

Use the mpls te igp metric command to assign a metric to the MPLS TE tunnel.

Use the undo mpls te igp metric command to restore the default.

By default, TE tunnels take their IGP metrics.

# Assign MPLS TE tunnel 0 a relative metric of -1 for enhanced SPF calculation in 
IGP.

mpls te igp shortcut [ isis | ospf ]

Tunnel interface view

isis: Sets the IGP protocol to IS-IS.

ospf: Sets the IGP protocol to OSPF.

Use the mpls te igp shortcut command to enable IS-IS or OSPF to consider the 
MPLS TE tunnel in its enhanced SPF calculation when the tunnel is up. If no IGP 
protocol is specified, the command applies to both OSPF and IS-IS.

Use the undo mpls te igp shortcut command to restore the default.

By default, IGP does not consider MPLS TE tunnels in its enhanced SPF calculation.
