OSPF Area ID Settings
This window allows the configuration of OSPF Area IDs and to designate these areas as either Nor-
mal or Stub. Normal OSPF areas allow Link-State Database (LSDB) advertisements of routes to
networks that are external to the area, while stub areas do not allow the LSDB advertisement of
external routes. Stub areas use a default summary external route (0.0.0.0 or Area 0) to reach external
destinations.
To set up an OSPF Area configuration click the OSPF Area Settings link to open the following window:

set to the table.
To remove an Area ID configuration set, simply click the [X] in the Delete column for the configura-
