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.

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.
