Configuring the Router 3-11
Connecting to a Router Using Point-to-Point Protocol
Point-to-Point Protocol (PPP) is a standard means of transporting multiprotocol datagrams over
point-to-point links and has been adopted as a method of interoperation between different
manufacturers. Although PPP is standards-based, implementation options vary. PPP can include
one of the following levels of security:
• Password Authentication Protocol (PAP)
• Challenge Handshake Authentication Protocol (CHAP)
If either PAP or CHAP authentication is to be used, it is necessary to preconfigure the paths. The
paths contain the relevant passwords to be used in the authentication process.
For further information, refer to Chapter 4, “Menus and Commands.”
Before you start, you need to know the following:
• The ISDN Number of the remote router
• The manufacturer and model of the remote router
• If PAP Authentication is to be used:
— The PAP User ID (System or Login name) assigned by your network provider for calls
from your router
— The PAP Password of your router (Outgoing Password) assigned by your network
provider for calls from your router
— The PAP User ID of the remote router (Path Name) assigned by your network provider for
calls to your router
— The PAP Password of the remote router (Incoming Password) assigned by your network
provider for calls to or from your router
• If CHAP Authentication is to be used:
— The CHAP User ID (System or Login Name) assigned by your network provider for calls
from your router
— The CHAP password (CHAP Secret) assigned by your network provider for calls from
your router
— The CHAP User ID of the remote unit (Path Name) assigned by your network provider for
calls to your router
