Configuring Authentication

You can configure the router to authenticate RIP route queries. By default, authentication is disabled. You can use the following authentication method:

Simple authentication—Uses a text password that is included in the transmitted packet. The receiving router uses an authentication key (password) to verify the packet.
MD5 authentication—Creates an encoded checksum that is included in the transmitted packet. The receiving router uses an authentication key (password) to verify the packet’s MD5 checksum.

To enable authentication and specify an authentication method and password, include the authentication-key and authentication-type statements:




authentication-key password;

authentication-type type;

For a list of hierarchy levels at which you can configure these statements, see the statement summary sections for these statements.

The password can be up to 16 contiguous characters and can include any ASCII strings.
