<p>In addition to options common for all to other protocols, RIP supports the following ones:
<descrip>
- <tag/authentication none|password|md5/ selects authentication method to be used. <cf/none/ means that
- packets are not authenticated at all, <cf/password/ means that a plaintext password is embedded
+ <tag/authentication none|plaintext|md5/ selects authentication method to be used. <cf/none/ means that
+ packets are not authenticated at all, <cf/plaintext/ means that a plaintext password is embedded
into each packet, and <cf/md5/ means that packets are authenticated using a md5 cryptographic
hash. If you set authentication to not-none, it is a good idea to add <cf>passwords { }</cf>
section. Default: none.
