In the following example, the show ospf mpls traffic-eng EXEC command verifies that the MPLS TE
links on area instance 3 are configured correctly:
RP/0/RP0/CPU0:router# show ospf mpls traffic-eng link

Sample Output for the show ospf Command After Configuring MPLS TE
In the following example, the show route ospf EXEC command verifies that the MPLS TE tunnels
replaced POS interface 0/3/0/0 and that configuration was performed correctly:
RP/0/RP0/CPU0:router# show route ospf 1
