Chapter 36 OSPF To configure an area, set the related fields in the OSPF Configuration screen. Figure 166 IP Application > OSPF Configuration: Area Setup 336 The following table describes the related labels in this screen. Table 117 IP Application > OSPF Configuration: Area Setup LABEL Name Area ID DESCRIPTION Enter a descriptive name (up to 32 printable ASCII characters) for identification purposes. Enter a 32-bit ID (that uses the format of an IP address in dotted decimal notation) that uniquely identifies an area. Authenticati on A value of 0.0.0.0 indicates that this is a backbone (also known as Area 0). You can create only one backbone area on the Switch. 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 Select this option to set the Switch to not send/receive LSAs. Summary Default Route Cost Specify a cost (between 0 and 16777215) 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. XGS4700-48F User's Guide
