UVA Material

• Router Lab Exercises from ITLab manual
• ITLab primer
• 1-pager with selected lab exercises
• ITLab manual
• Re-Boot Camp IOS and Linux configuration
• Linux installation and customization
• Connecting routers and hosts
• IOS issues (password recovery, updating images)

What is the VINTLab about?

• In a set of closed lab sessions, students
  conduct supervised experiments on the networking
  equipment of the VINTLab. Students gain hands-on
  experience with networking hardware and software,
  and learn how the protocols of the Internet
  interact.

History

• Spring 98 Kevin Thompson indicates a possible
  donation of several Cisco 7000 routers by MCI
• Aug. 98 Letter by Vint Cerf to Dean of
  Engineering at UVA
• .MCI Telecommunications, together with Cisco
  Systems, Inc., is committed to forming an
  Internet laboratory at the University of
  Virginia
• Dec. 99 First batch of 5 Cisco routers arrive
• Jan. 99 Course started CS551 Internet
  Engineering
• April 99 Official ribbon cutting of the
  VINTLab by Vint Cerf
• VINTLab is mentioned on the floor of the US
  Congress
• Spring 00 Internet Engineering offered for
  the second time
• Spring 01 and a third time, this time with
  Linux
• Since Fall 00 Adopted VINTLab to the ITL
  equipment
• June 01 ITL workshop

Objectives of VINTLab / Internet Engineering
course

• Make education in computer networking more
  concrete.
• Dont teach a vendor-specific course on router
  configuration
• Use science labs as model
• Build on prior knowledge
• Cisco 7000 routers are tools and not the object
  of study
• Exploit students familiarity with PCs
• Students should feel in control of the equipment
• Closed lab sessions
• Have Fun!

  Technology,
• Jim Massa, Director of Global Government
  Alliances at Cisco, and

The ITLab Manual
15
Background

• CAIDAs NSF supported ITL program distributes
  routers to more than 20 institutions
• Issue Effort to generate course content is
  significant
• UVAs VINTLab manual was adopted to ITLab
  equipment
• Objectives
• Provide a set of canned lab exercises to
  institutions
• Jump-start courses on internet engineering
• This workshop exposes instructors to the ITLab

16
ITLab Equipment

• Lab manual was written for a standard ITLab
• Standard ITLab assumes 3 Cisco 7000 routers
• We assume that some equipment will be purchased
  by ITL sites (PCs, FDDI cards, cables)

• 3 Cisco 7000 Routers
• 6 Linux PCs
• 2 FDDI cards
• Cables and connectors

17
Lab Structure

• Prelab
• Students read material needed for the lab and
  turn in solutions to exercises
• Lab Session
• 2 hour-long supervised lab section
• Students do not have access to lab equipment
  outside this block
• Postlab (Lab Report)
• Lab measurements are interpreted and used to
  answer problems

18
Lab 1 Introduction to the ITLab

• Topics Overview of the equipment, Unix
  exercises, basics of tcpdump and ethereal

19
Lab 2 Single Segment IP Networks

• Topics Details of ethereal, configuring network
  interfaces, netstat command, experiments with
  ARP, snooping passwords

20
Lab 3 Multiple Segment IP Networks and Static
Routing

• Topics Setting up a computer as a router, static
  routing, update routing table update via ICMP,
  subnet masks

21
Lab 4 Configuring a Commercial IP Router

• Topics Access to routers via serial port, setup
  of a commercial router, basics of Cisco IOS

22
Lab 5 Dynamic Routing Protocols (RIP and OSPF)

• Topics Routing updates, Convergence of routing
  protocols after topology changes under RIP and
  OSPF, split-horizon and triggered updates with RIP

23
Lab 6 Transport Layer Protocols UDP and TCP

• Topics IP fragmen-tation, throughput measurement
  of TCP, TCP slow start and congestion
  avoi-dance,TCP error control
