OSPF Commands
243
A default cost can be defined only for a stub area. To define a stub area, use the
ospf area stub
command.
Example
The following example specifies a cost of 10000 for the default summary route sent into a stub area
number 192.168.3.1.
ospf
The
ospf
interface configuration command creates the OSPF routing process on an interface. To
delete the OSPF routing process, use the
no
form of this command.
Syntax
ospf [area-id]
no ospf
Area-id is an area associated with the OSPF address range. It can be specified as either a
decimal value or as an IP address.
Default Configuration
OSPF is not created on an interface.
Command Mode
IP Interface Configuration mode
User Guidelines
After creating an OSPF process on an interface, the OSPF process must be activated on the
interface using the
ospf enable command.
If the specified area-id has not yet been created, using the
ip interface configuration ospf
area
command, then it is auto-created using this command.
An OSPF area that is auto-created is not displayed in the configuration file.
An auto-created OSPF area is deleted only after a subsequent reboot, if the OSPF
interface is deleted.
If no area is designated, the backbone area is associated with the IP interface. If the backbone
has not yet been created, it is auto-created. Note that the negation of the
area
command does
not appear in the configuration file, because it is, in fact, the default. However, it does appear
when using the
show ospf
command, because it was automatically created.
