2. 2 Packet Tracer V3.2 A simulation product for designing, and testing a network before implementation on the actual hardware devices.

3. 3 Melbourne Router Sydney Router Melb_Hub Syd_Hub Network Address 193.105.10.0 Network Address 145.50.0.0 Network Address 13.0.0.0 UTP Cable Serial Cable Melb PC Syd PC Case Study 1 – The Concept of an IP Network Fa 0/0 S 2/0 DCE

4. 4 Melbourne Router - Configuration ! The FastEthernet interface configuration: interface fa 0/0 ip address 145.50.0.1 255.255.0.0 description Link to Melb Hub no shutdown ! The Serial interface configuration: interface serial 2/0 ip address 13.0.0.1 255.0.0.0 ! This is DCE end of the link clock rate 64000 description Link to Sydney Router no shutdown ! Set hostname of the router hostname Melbourne

5. 5 Melbourne PC - Configuration Need to set the PC’s IP address to 145.50.0.2 Need to set PC’s subnet mask to 255.255.0.0 Need to set PC’s gateway to 145.0.0.1

6. 6 Sydney Router - Configuration ! The FastEthernet interface configuration: interface fa 0/0 ip address 193.105.10.1 255.255.255.0 description Link to Syd Hub no shutdown ! The Serial interface configuration: interface serial 2/0 ip address 13.0.0.2 255.0.0.0 description Link to Melbourne Router no shutdown ! Set hostname of the router hostname Sydney

7. 7 Sydney PC - Configuration Need to set the PC’s IP address to 193.105.10.2 Need to set PC’s subnet mask to 255.255.255.0 Need to set PC’s gateway to 193.105.10.1

8. 8 Link (Point-to-Point) Testing Use the ping command to test each link is working Note you cannot ping from Melbourne PC to Sydney PC, Why is this the case?

9. 9 Routing Protocols Melbourne Router router rip version 2 network 13.0.0.0 network 145.50.0.0 Sydney Router router rip version 2 network 13.0.0.0 network 193.105.10.0

10. 10 Path (End-to-End) Testing Use the ping, and traceroute command to test a path exists between the Melbourne PC and the Sydney PC If a path exists, Why is this the case?

11. 11 Discussion Points Concept of an IP Network –IP Address Classes –Types of Address Network Host Broadcast –Address Mask Default masks for each class Purpose of the mask

12. 12 Discussion Points How do IP datagrams travel between networks? –Routing Protocols RIP –Advertising networks –The Routing Table The Interface –What is an interface? –What is its purpose? –How is it identified?

13. 13 Discussion Points Router IOS Modes –User Executive –Privileged Executive –Global Configuration –Interface Configuration –Router Configuration System Testing and Trouble Shooting –Step by Step Testing –Link (Point-to-Point) Testing –Path (End-to-End) Testing –Use of show commands –Use of debug commands
