25.4.1 View OSPF Area Information Table
The bottom of the OSPF Configuration screen displays a summary table of all the OSPF
areas you have configured.
Figure 86 OSPF Configuration: Summary Table
The following table describes the related labels in this screen.
Authentication Select an authentication method (Simple or MD5) to activate authentication. Select
None (default) to disable authentication.
Usually interface(s) and virtual interface(s) should use the same authentication method
as the associated area. If interface(s) and virtual interface(s) use different
authentication methods than the associated area, the authentication methods are
based on the interface(s) and virtual interface(s) settings.
Stub Network Select this option to set the area as a stub area.
If you enter 0.0.0.0 in the Area ID field, the settings in the Stub Area fields are ignored.
No Summary Select this option to set the switch to not send/receive LSAs.
Default Route
Cost
Specify a cost (between 0 and 16777214) used to add a default route into a stub area
for routes which are external to an OSPF domain. If you do not set a route cost, no
default route is added.
Add Click Add to save your changes to the switch’s run-time memory. The switch loses
these changes if it is turned off or loses power, so use the Save link on the top
navigation panel to save your changes to the non-volatile memory when you are done
configuring.
Cancel Click Cancel to start configuring the above fields again.
Clear Click Clear to set the above fields back to the factory defaults.
