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 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]
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.
Applying cost for OSPFv3
Change in bandwidth directly affects the cost of OSPF routes.
● Explicitly specify the cost of sending a packet on an interface.
INTERFACE mode
ipv6 ospf interface-cost
○ interface-cost:The range is from 1 to 65535. Default cost is based on the bandwidth.
● Specify how the OSPF interface cost is calculated based on the reference bandwidth method. The cost of an interface is
calculated as Reference Bandwidth/Interface speed.
ROUTER OSPFv3
auto-cost [reference-bandwidth ref-bw]
To return to the default bandwidth or to assign cost based on the interface type, use the no auto-cost [reference-
bandwidth ref-bw] command.
○ ref-bw: The range is from 1 to 4294967. The default is 100 megabits per second.
Enabling OSPFv3 Graceful Restart
Follow the procedure in this section to configure 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 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.
