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.
