The following parameters are used for general OSPF configuration:
Parameter
Description
OSPF Route ID
A 32-bit number (in the same format as an IP address
− xxx.xxx.xxx.xxx) that uniquely
identifies the Switch in the OSPF domain. It is common to assign the highest IP address
assigned to the Switch (router). In this case, it would be 10.53.13.189, but any unique 32-bit
number will do. If 0.0.0.0 is entered, the highest IP address assigned to the Switch will
become the OSPF Route ID.
Current Route ID
Displays the OSPF Route ID currently in use by the Switch. This Route ID is displayed as a
convenience to the user when changing the Switch’s OSPF Route ID.
State
Allows OSPF to be enabled or disabled globally on the Switch without changing the OSPF
configuration.
OSPF Area Setting
This menu allows the configuration of OSPF Area IDs and to designate these areas as either Normal or Stub. Normal OSPF areas
allow Link-State Database (LSDB) advertisements of routes to networks that are external to the area. 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 Layer 3 Features > OSPF > OSPF Area Settings link to open the following dialog
box:
Figure 8- 30. OSPF Area Settings and Table window
To add an OSPF Area to the table, type a unique Area ID (see below) select the Type from the drop-down menu. For a Stub type,
choose Enabled or Disabled from the Stub Import Summary LSA drop-down menu and determine the Stub Default Cost. Click
the Add/Modify button to add the area ID set to the table.
To remove an Area ID configuration set, simply click in the Deletecolumn for the configuration.
