25.4 Configuring 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.

A value of 0.0.0.0 indicates that this is a backbone (also known as Area 0). You can
