Point to point protocol

Internet

ISP

  • Many Internet users connect from home

  • Dial-up (Telephone line)

  • Leased line

Point-to-Point Protocol





Ppp layers stacks
PPP Layers (stacks)

  • Link Control Protocol (LCP)

  • Authentication Protocols

  • Network Control Protocol (NCP)

  • Bit Padding

  • Digital Signals (DS) Services


Ppp frame
PPP Frame

Address: broadcast (avoid data link address)

Control: U-frame format (HDLC)

Protocol: defines data field


Link control protocol lcp
Link Control Protocol (LCP)

  • Link Control Protocol (LCP)

    • establish/terminate

    • maintain

    • configuration

Code: 01=Config-request

02=Config-ack

05=Terminate-req



Authentication
Authentication

  • Mostly PPP is dial-up user.

  • Validating the user is important

  • Password Authentication Protocol (PAP)

    • 2-way handshake

    • Less secure

  • Challenge Handshake Authentication Protocol (CHAP)

    • 3-way handshake

    • More secure (no password sent)







Internetwork protocol control protocol ipcp
Internetwork Protocol Control Protocol (IPCP)

  • Establish / Terminate @ network layer connection (IP)

  • Code 01:Configure-request

  • 02:Configure-ack





Lab

  • 3.3.2 PPP encapsulation

  • 3.3.3 PPP authentication

  • 3.3.5 Troubleshooting PPP
