Configuring Default Route Information Settings for OSPF Routing
An OSPF vRouter, by default, does not generate a default route into the OSPF domain. In order for OSPF to generate a default route, you must explicitly configure the vRouter with this information.
There are two ways to inject a default route into a normal area.
- If the ASBR already has the default route in the routing table, you can advertise the existing 0.0.0.0/0 into the OSPF domain with the ospf-default-information parameter.
- If the ASBR doesn't have a default route, you can add the keyword always to the ospf-default-information command. However, we recommend not to add the always keyword.
The OSPF vRouter advertises a default route into the OSPF domain, even if a route to 0.0.0.0 is configured.
When you configure the metric type, you can use the parameters described for the vrouter-* commands for configuring a route map. These parameters control default route generation for IPv4 and IPv6 default routes.
