This article will show you how to configure PPP (Point-to-Point Protocol) using Cisco SDM in order to enable communication between two routers connected through a serial link. This tutorial includes how to enable PPP encapsulation, and configure CHAP authentication. This article is designed for CCNA students, network engineers, and anyone looking to configure PPP using Cisco SDM (Cisco SDM is part of the CCNA syllabus).
The PPP (Point-to-Point Protocol) is a set of standard protocols to ensure interoperability of remote access software from various publishers. A compatible connection PPP can call remote networks through a PPP server industry standard. PPP also allows a remote access server to receive incoming calls and ensure network access to remote access software from other vendors, standards-compliant PPP.
The standards also allow PPP advanced features that are not available with old standards, including SLIP. PPP supports several authentication methods and data compression and encryption. Most versions of PPP automate the entire process of logging on. The PPP also supports multiple protocols LAN. You can use TCP / IP or IPX as network protocol. IPX / SPX is not available on Itanium-based versions of Windows operating systems.
PPP is the foundation of PPTP (Point-to-Point Tunneling Protocol) and Protocol (L2TP Layer Two Tunneling Protocol) used in the VPN (Virtual Private Network) secure. PPP is the main standard for most remote access software.
The LCP (Link Control Protocol) defines and configures the PPP frames. PPP frames define how data is encapsulated before being transmitted over a WAN. The standard PPP frame format ensures that remote access software from any publisher can communicate and identify data packets from any remote access software conforms to PPP.
The PPP (Point-to-Point Protocol) is a set of standard protocols designed to ensure interoperability devices connected through a wide area network. A compatible connection PPP can call remote networks through a PPP server. PPP also allows a remote access server to receive incoming calls and ensure network access to remote access software from other vendors.
The Point-to-Point Protocol (PPP) provides a standard method for transporting multi-protocol datagrams between two peers. PPP is comprised of three main components:
" A method for encapsulating multi-protocol datagrams.
" A Link Control Protocol (LCP) for establishing, configuring, and testing the data-link connection.
" A family of Network Control Protocols (NCPs) for establishing and configuring different network-layer protocols.
Follow these steps in order to configure PPP on a serial interface using Cisco SDM:
Step 1: Open Cisco SDM.
Step 2: Click Configure in order to start Configuration.
Step 3: In the tasks bar, click Interfaces and Connections.
Step 4: Select the Serial (PPP, HDLC, or Frame Relay) option, and then click Create New Connection.
Step 5: Click Next.
Step 6: In the Available Interfaces drop-down list, select the interface to configure, and then click Next.
Step 7: Choose PPP as the encapsulation type, and click Next.
Step 8: Enter the IP address and the subnet mask for your serial interface, and then click Next.
Step 9: Choose Default Static Route if you want to make the Router on the other end of the PPP link your default gateway. If not, simply click Next.
Step 10: Click Finish, and then click OK.
