| 4.3.4 | Writing the IOS command to configure CHAP authentication

The following methods can be used to simplify CHAP configuration tasks on the router: You can use the same host name on multiple routers-When you want remote users to think they are connecting to the same router when authenticating, configure the same host name on each router: Router(config-if)# ppp chap hostname <hostname> You can use a password to authenticate an unknown host. This is to limit the number of username/password entries in the router. To use this, configure a password that will be sent to hosts that want to authenticate the router: Router(config-if)# ppp chap password <secret> This password is not used when the router authenticates a remote device.
