Introduction
An introduction to the software and organization of the Internet Lab.
Internet Lab
• GNS3 network simulation software
• The labs will use virtual PCs, Ubuntu OS (Linux based),
Ethernet hubs and switches and Cisco 2611 routers
• The labs will also use Wireshark Traffic Capture and
Analyzer software (and for Macs X11 is also required)
The Lab Equipment
• PCs are labeled as: PC1, PC2, PC3, PC4…..
• Labs will use VirtualBox and Virtual PCs instead of the embedded VPCS
in GNS3.
• Routers are labeled: Router1, Router2, Router3, Router4…..
• Routers run Cisco IOS 12.0 or a later version.
• Hubs and Ethernet switches are all embedded in GNS3.

Core Labs
• Lab 1 – Introduction to the Internet Lab
Overview of the Internet Lab Software.
• Lab 2 – Single Segment IP Networks
Configuring a network interface for IP networking; address resolution
with ARP; security problems of common Internet applications. Traffic
capture
• Lab 3 – Static routing
IP forwarding and routing between IP networks; setup a Linux PC and a
Cisco router as an IP router; manual configuration of routing tables.
• Lab 4 – Dynamic Routing Protocols
Routing protocols RIP, OSPF and BGP; count-to-infinity problem in RIP;
hierarchical routing in OSPF; setup of autonomous systems in BGP.
• Lab 5 – Transport Protocols: UDP and TCP
Data transmissions with TCP and UDP; TCP connection management;
TCP flow control; retransmissions in TCP; TCP congestion control.
Advanced Labs
Lab 6 – LAN switching
LAN switching in Ethernet networks; forwarding of Ethernet frames
between LAN switches/bridges; spanning tree protocol for loop free
routing between interconnected LANs.
Lab 7 - NAT and DHCP
Setup of a private network; dynamic assignment of IP addresses with
DHCP.
Lab 8 – Domain Name System
Domain name resolution with DNS; name server hierarchy; setup of a
DNS root server.
Lab 9 – SNMP
Network management with SNMP; SNMP agents and SNMP managers;
Security features of different versions of SNMP.
Lab 10 – IP Multicast
Multicast group management with IGMP; IP multicast forwarding; Multicast
routing protocols PIM-SM and PIM-DM.
Structure of the Labs
•
•
•
Each lab has two phases: a lab session, and a lab analysis.
Lab Session
– Lab exercises are performed on the GNS3 software. All lab exercises can be
completed without supervision. The time to complete a lab session should be
three hours on the average, but may vary. Complete the laboratory activities
to the extent that you can. The activities during the lab session are not graded
Lab Analysis
– At the end of most lab exercises are a series of questions. It is recommended
that you answer the questions using the data you collected whilst running the
exercises. The lab quizzes will be based on the information you have learnt in
your lab sessions.
