Redistributing Routes
You can add routes from other routing instances or protocols to the OSPFv3 process.
With the redistribute command, you can include RIP, static, or directly connected routes in the OSPF process. Route redistribution is
also supported between OSPF Routing process IDs.
To add redistributing routes, use the following command.
• 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]
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 OSPFv2 Graceful Restart
Graceful restart is enabled for the global OSPF process.
The Dell EMC Networking implementation of OSPFv2 graceful restart enables you to specify:
• grace period — the length of time the graceful restart process can last before OSPF terminates it.
• helper-reject neighbors — the router ID of each restart router that does not receive assistance from the congured router.
• mode — the situation or situations that trigger a graceful restart.
• role — the role or roles the congured router can perform.
NOTE
: By default, OSPFv2 graceful restart is disabled.
