Configuration steps:

:
1:
Verify that each router has assigned the host name. To assign a host name, you can enter it in global configuration mode
Hostname name
This name must match the user name expected by the
authentication router at the other end of the link
2:
Use the username name password password global mand on each router to define the expected remote routing
Username and password obtained by the device.
Such as: username R3 password Cisco
Note: R3 is the opposite end
End to end
The host name of the end router, Cisco is the password, and the password must be the same at both ends.

And CHAP
PAP is a two way handshake that provides a simple way to build identity for remote nodes. PAP only on the initial link
Execution during establishment period.
CHAP uses the three handshake CHAP in the link establishment, and then periodically uses the three handshake to test the remote
Path node identifier.
If you configure the PPP authentication chap PAP router, you will try to use chap to verify all ing
PPP session. If the remote device does not support chap, the router will attempt to validate the PPP session using pap. If the equipment is not
Supports chap and does not support PAP, authentication will fail. And the PPP session will close.
If you configure the PPP authentication PAP chap router, you will try to use PAP to verify all ing

Any protocol that supports authentication will fail. And the PPP session will close.
