Graceful Shutdown Support for OSPFv3
This feature provides the ability to temporarily shut down an Open Shortest Path First version 3 (OSPFv3) process or interface in the least disruptive manner, and to notify its neighbors that it is going away. A graceful shutdown of a protocol can be initiated on all OSPFv3 interfaces or on a specific interface.
Information About Graceful Shutdown Support for OSPFv3
OSPFv3 Graceful Shutdown
The Graceful Shutdown for OSPFv3 feature provides the ability to temporarily shut down the OSPFv3 protocol in the least disruptive manner and to notify its neighbors that it is going away. All traffic that has another path through the network will be directed to that alternate path. A graceful shutdown of the OSPFv3 protocol can be initiated using the shutdown command in router configuration mode or in address family configuration mode.
This feature also provides the ability to shut down OSPFv3 on a specific interface. In this case, OSPFv3 will not advertise the interface or form adjacencies over it; however, all of the OSPFv3 interface configuration will be retained. To initiate a graceful shutdown of an interface, use the ipv6 ospf shutdown or the ospfv3 shutdown command in interface configuration mode.

Configuration Examples for Graceful Shutdown Support for OSPFv3
Example: Configuring Graceful Shutdown of the OSPFv3 Process
The following example shows how to configure graceful shutdown of the OSPFv3 process in IPv6 router OSPF configuration mode configuration mode:
ipv6 router ospf 6
router-id 10.10.10.10
shutdown
The following example shows how to configure graceful shutdown of the OSPFv3 process in router OSPFv3 configuration mode:
!
router ospfv3 1
shutdown
!
address-family ipv6 unicast
exit-address-family
The following example shows how to configure graceful shutdown of the OSPFv3 process in address-family configuration mode:
!
router ospfv3 1
!
address-family ipv6 unicast
shutdown
exit-address-family
Example: Configuring Graceful Shutdown of the OSPFv3 Interface
The following example shows how to configure graceful shutdown of the OSPFv3 interface using the ipv6 ospf shutdown command:
!
interface Serial2/1
no ip address
ipv6 enable
ipv6 ospf 6 area 0
ipv6 ospf shutdown
serial restart-delay 0
end
The following example shows how to configure graceful shutdown of the OSPFv3 interface using the ospfv3 shutdown command:
!
interface Serial2/0
ip address 10.10.10.10 255.255.255.0
ip ospf 1 area 0
ipv6 enable
ospfv3 shutdown
ospfv3 1 ipv6 area 0
serial restart-delay 0
end
