When using the 

username

 command, remember that the username is the hostname of 

the remote router that’s connecting to your router. And it’s case sensitive too. Also, the 

password on both routers must be the same. It’s a plain-text password that you can see 

with a 

show run

 command, and you can encrypt the password by using the command 

service password-encryption

. You must have a username and password configured 

for each remote system you plan to connect to. The remote routers must also be similarly 

configured with usernames and passwords.

Now, after you’ve set the hostname, usernames, and passwords, choose either CHAP or 

PAP as the authentication method:
