Configuring the OSPF Area:
Interfaces window
1. In the Area field, specify the area number as follows:
Backbone—Select this option to define area 0.
Number—Select this option to define a non-zero area. The area is
defined in the Area Number field. Values can be simple numbers
(like 3), or "dotted decimal" (like IP addresses). Areas are 32 bit
numbers.
2. In the Stub field, specify the areas where there are no external routes as
follows:
Yes—Select this option If the Sidewinder G2 is an intra-area router
inside a stub area. In the Default Cost area, specify the cost of the
default route. If this is the Area Border Router (ABR) for the stub
area, this indicates the cost of the default route that will be flooded
into the stub area.
No—Select this option if the Sidewinder G2 is not an intra-area
router inside a stub area.
3. To modify the Interfaces table, see “Configuring the OSPF Area:
Interfaces window” on page C-9. The Interfaces table defines the
configuration for each OSPF interface on the Sidewinder G2.
Note: Do not change the Networks field unless directed to by Secure Computing.
