Usage Guidelines
•
Simple authentication uses only a text string as the password in the packet. This helps to protect the
routers from a configuration mishap. MD5 authentication is used to protect the system from malicious
actions.
•
MD5 authentication is used to encrypt the information that is sent over the network. MD5 authentica-
tion uses shared secret key. The Key is used to sign the packets with an MD5 checksum to sign the
packet, so that the packets cannot be tampered. As the key is not included in the packet, snooping the
key is not possible.
•
Use the Key parameter to configure the password for Simple or MD5 authentication. Alternatively, use
the encrypt-key parameter to configure the password by supplying the encrypted form of the password
as the encrypt-key. The Configuration snapshot always displays the password in the encrypted form.
You should use only this key parameter during the CLI configuration.
•
If the encrypt-key parameter is used to configure the password through the CLI, then its value should
be the same as the one that appears in the configuration snapshot. Only valid system generated values
are accepted as encrypt-key.
•
This command configures the authentication type of ISIS protocol globally. These settings can be over-
ridden at each level.
