Configuring Ospfv3 Graceful Restart - Cisco ASR 9000 Series Routing Configuration Manual

Configuring OSPFv3 Graceful Restart

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

DETAILED STEPS
Command or Action
Step 1 configure
Step 2 router ospfv3 process-name
Example:

Purpose
Enters router configuration mode for OSPFv3. The
process name is a WORD that uniquely identifies an
OSPF routing process. The process name is any
alphanumeric string no longer than 40 characters
without spaces.
Enables graceful restart on the current router.
Specifies a maximum duration for a graceful restart.
• The default lifetime is 95 seconds.
• The range is 90 to 3600 seconds.
