Configuring the OSPF Testing Authentication Topology Example

The authentication type for OSPF can be configured as Simple Password Authentication, Message-Digest Authentication, or Null Authentication.

Use Interface Configuration mode to perform authentication-related configuration.

Enable OSPF over the VLAN interface and associate the interface with an OSPF area before configuring OSPF authentication. See Enable OSPF Over the VLAN Interface.
