Appendix C: Configuring Dynamic Routing with OSPF
Setting up OSPF routing on the Sidewinder G2
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 609. 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.
When you click New or Modify under the Interfaces table, the following window
appears:
1 In the Interfaces field, specify the Sidewinder G2 IP address for each
interface that should use OSPF.
2 In the Cost field, specify the metric that OSPF should advertise when
calculating routes using this interface. (OSPF leaves this undefined, but it is
an integer.)
3 In the Enabled field, specify whether this interface should currently run
OSPF.
4 In the Retransmit Interval field, specify the retransmit interval (in seconds)
between link state advertisement retransmits (the range is 0-65535).
5 In the Transit Delay field, specify a reasonable estimate on how long it
takes an OSPF packet to be transmitted on this interface (range is 0-
65535). Except for very long delay paths, this parameter will normally be
set to 1.
