Default - H3C s3600 series Command Manual

Use the undo authentication-mode command to cancel the authentication attribute of this area.
By default, an area does not support authentication attribute.
All the routers in one area must use the same authentication mode (no authentication, simple text
authentication, or MD5 cipher text authentication). If the mode of supporting authentication is
configured, all routers on the same segment must use the same authentication key.
Use the ospf authentication-mode simple command to configure a simple text authentication key.
Use the ospf authentication-mode md5 command to configure the MD5 cipher text authentication key
if the area is configured to support MD5 cipher text authentication mode.
After you configure one OSPF area to support the authentication attribute, you need to use the ospf
authentication-mode command to set the authentication mode on interfaces. When configuring virtual
link authentication, you can use the authentication-mode command to specify the authentication
mode as MD5 cipher text or simple text for the backbone area.
Related commands: ospf authentication-mode, vlink-peer.
