• Specify which routes are redistributed into the OSPF process.
CONF-IPV6-ROUTER-OSPF mode
redistribute {bgp | connected | static} [metric metric-value | metric-type
type-value] [route-map map-name] [tag tag-value]
Configure the following required and optional parameters:
– bgp | connected | static: enter one of the keywords to redistribute those routes.
– metric metric-value: The range is from 0 to 4294967295.
– metric-type metric-type: enter 1 for OSPFv3 external route type 1 OR 2 for OSPFv3 external route
type 2.
– route-map map-name: enter a name of a configured route map.
– tag tag-value: The range is from 0 to 4294967295.
Configuring a Default Route
To generate a default external route into the OSPFv3 routing domain, configure FTOS.
To specify the information for the default route, use the following command.
• Specify the information for the default route.
CONF-IPV6-ROUTER-OSPF mode
default-information originate [always [metric metric-value] [metric-type
type-value]] [route-map map-name]
Configure the following required and optional parameters:
– always: indicate that default route information is always advertised.
– metric metric-value: The range is from 0 to 4294967295.
– metric-type metric-type: enter 1 for OSPFv3 external route type 1 OR 2 for OSPFv3 external route
type 2.
– route-map map-name: enter a name of a configured route map.
Enabling OSPFv3 Graceful Restart
Graceful restart for OSPFv3 is supported on the Z9000 platform.
For more information about graceful restart, refer to Graceful Restart.
By default, OSPFv3 graceful restart is disabled and functions only in a helper role to help restarting neighbor routers in
their graceful restarts when it receives a Grace LSA.
To enable OSPFv3 graceful restart, enter the ipv6 router ospf process-id command to enter OSPFv3
configuration mode. Then configure a grace period using the graceful-restart grace-period command. The
grace period is the time that the OSPFv3 neighbors continue to advertise the restarting router as though it is fully
adjacent. When you enable graceful restart (restarting role), an OSPFv3 restarting expects its OSPFv3 neighbors to help
when it restarts by not advertising the broken link.
When you enable the helper-reject role on an interface using the ipv6 ospf graceful-restart helper-
reject command, you reconfigure OSPFv3 graceful restart to function in a restarting-only role. OSPFv3 does not
participate in the graceful restart of a neighbor.
NOTE: Enter the ipv6 ospf graceful-restart helper-reject command in Interface configuration
mode.
• Enable OSPFv3 graceful restart globally by setting the grace period (in seconds).
