Default Route Advertisement

default routes are advertised in OSPF.

  • OSPF supports advertising the default route into the OSPF domain. The default route is advertised by using the command default-information originate [always] [metric metric-value] [metric-type type-value] underneath the OSPF process.

Default Route Topology & Configuration

The always optional keyword advertises a default route even if a default route does not exist in the RIB. The route metric can be changed with the metric metric-value option. The metric type can be changed with the metric-type type-value option.     Other useful information:
