redistribute {bgp | connected | static} [metric metric-value | metric-type type-value] [route-
map map-name] [tag tag-value]
Congure 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 congured route map.
– tag tag-value: The range is from 0 to 4294967295.
Conguring a Default Route
To generate a default external route into the OSPFv3 routing domain, congure the following parameters.
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]
Congure 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 congured route map.
Enabling OSPFv3 Graceful Restart
Follow the procedure in this section to congure graceful restart for OSPFv3. 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.
.
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 conguration mode. Then
congure 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
recongure 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 conguration mode.
NOTE: For graceful-restart conguration to work, you must congure grace-period. Use graceful-restart grace-period
command to congure grace-period.
• Enable OSPFv3 graceful restart globally by setting the grace period (in seconds).
