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
O E2 192.168.10.0/24 [110/20] via 0.0.0.0, 00:00:15, tunnel2
O E2 192.168.11.0/24 [110/20] via 0.0.0.0, 00:00:15, tunnel2
O E2 192.168.1244.0/24 [110/20] via 0.0.0.0, 00:00:15, tunnel2
O 192.168.12.0/24 [110/2] via 0.0.0.0, 00:00:15, tunnel2
Configuring OSPFv3 Graceful Restart
This task explains how to configure a graceful restart for an OSPFv3 process. This task is optional. 
SUMMARY STEPS
1. configure
2. router ospfv3 process-name
3. graceful-restart
4. graceful-restart lifetime
5. graceful-restart interval <seconds>
6. graceful-restart helper
