15 OSPF Commands
15.1 area authentication
To enable authentication for an Open Shortest Path First (OSPF) area, use the area authentication
command in router configuration mode. To remove an authentication specification of an area or a
specified area from the configuration, use the no form of this command.
Command Syntax
area area-id authentication [message-digest]
no area area-id authentication
area-id Identifier of the area for which authentication is to be enabled. The identifier
can be specified as either a decimal value or an IP address.
message-digest (Optional) Enables Message Digest 5 (MD5) authentication on the area
specified by the area-id argument.
Default
Type 0 authentication (no authentication)
Command Mode
Router configuration
Usage
Specifying authentication for an area sets the authentication to Type 1 (simple password) as specified in
RFC 1247. If this command is not included in the configuration file, authentication of Type 0 (no
authentication) is assumed.
The authentication type must be the same for all routers and access servers in an area. The
authentication password for all OSPF routers on a network must be the same if they are to communicate
with each other via OSPF. Use the ip ospf authentication-key interface command to specify this
password.
If you enable MD5 authentication with the message-digest keyword, you must configure a password
with the ip ospf message-digest-key interface command.
To remove the authentication specification for an area, use the no form of this command with the
authentication keyword.
