32.4 Configure OSPF Areas
To ensure that the Switch receives only routing information from a trusted layer 3
devices, activate authentication. The OSPF supports three levels of authentication:
• 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.
