exceeding 8 characters.

key-id: ID of the authentication key in MD5 authentication mode in the range 
from 1 to 255.

key: MD5 authentication key. If it is input in a plain text form, MD5 key is a

form in a length of 24 characters when the display current-configuration 
command is executed. Inputting the MD5 key in a cipher text form with 24 
characters is also supported.

The passwords for authentication keys of the routers on the same network 
segment must be identical. In addition, using the authentication-mode 
command, you can set the authentication type of the area so as to validate the 
configuration.
