Chapter 28 OSPF 28.4 Configure OSPF Areas To ensure that the Switch receives only routing information from a trusted layer 3 devices, activate authentication. The OSPF supports three authentication methods: • None - no authentication is used. • Simple - authenticate link state updates using an 8 printable ASCII character password. • MD5 - authenticate link state updates using a 16 printable ASCII character password. To configure an area, set the related fields in the OSPF Configuration screen. Figure 123 OSPF Configuration: Area Setup The following table describes the related labels in this screen. Table 88 OSPF Configuration: Area Setup LABEL DESCRIPTION Name Enter a descriptive name (up to 32 printable ASCII characters) for identification purposes. Area ID Enter a 32-bit ID (that uses the format of an IP address in dotted decimal notation) that uniquely identifies an area. 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. 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.
