| NOTE: By default, there is no need to configure a hostname to be used for CHAP authentication on Cisco IOS routers as they will use the hostname configured on the router. There is also no need to define a password to be used for authentication since CHAP does not send the passwords across the link like PAP. Therefore, a hash will be created using the configured passwords in the username command. These passwords must be identical on both routers, otherwise authentication will fail! |
