3. CSE5807 - Case Study 2 3 Packet Tracer V3.2 A simulation product for designing, and testing a network before implementation on the actual hardware devices.

4. CSE5807 - Case Study 2 4 Brisbane Router Adelaide Router Bris_Hub Adel_Hub Subnet 92Subnet 85 Network Address 35.0.0.0/18 UTP Cable Serial Cable Bris PC Adel PC Case Study 2 – The Concept of IP Subnetting Fa 0/0 S 2/0 DCE Subnet 152 Host 262 Host 520

5. CSE5807 - Case Study 2 5 Brisbane Router - Configuration ! The FastEthernet interface configuration: interface fa 0/0 ip address 255.255.192.0 description Link to Brisbane Hub, Subnet 85 no shutdown ! The Serial interface configuration: interface serial 2/0 ip address 255.255.192.0 ! This is DCE end of the link clock rate 64000 description Link to Adelaide Router, Subnet 152 no shutdown ! Set hostname of the router hostname Brisbane

6. CSE5807 - Case Study 2 6 Brisbane PC - Configuration Need to set the PC’s IP address to address of Host 262 Need to set PC’s subnet mask to 255.255.192.0 Need to set PC’s gateway

7. CSE5807 - Case Study 2 7 Adelaide Router - Configuration ! The FastEthernet interface configuration: interface fa 0/0 ip address 255.255.192.0 description Link to Adelaide Hub, Subnet 92 no shutdown ! The Serial interface configuration: interface serial 2/0 ip address 255.255.192.0 description Link to Brisbane Router, Subnet 152 no shutdown ! Set hostname of the router hostname Adelaide

8. CSE5807 - Case Study 2 8 Adelaide PC - Configuration Need to set the PC’s IP address to address of Host 262 Need to set PC’s subnet mask to 255.255.192.0 Need to set PC’s gateway

9. CSE5807 - Case Study 2 9 Link (Point-to-Point) Testing Use the ping command to test each link is working Note you cannot ping from Brisbane PC to Adelaide PC, Why is this the case?

10. CSE5807 - Case Study 2 10 Routing Protocols Brisbane Router router rip version 2 network Adelaide Router router rip version 2 network

11. CSE5807 - Case Study 2 11 Path (End-to-End) Testing Use the ping, and traceroute command to test a path exists between the Brisbane PC and the Adelaide PC If a path exists, Why is this the case?

12. CSE5807 - Case Study 2 12 Discussion Points Concept of IP Subnetting –IP Address Classes –Classful Address –Two Level Classful Hierarchy Network-Prefix, Host-Number Routing tables growing in size Local administrators had to request another network number, before a new network could be installed at their site

13. CSE5807 - Case Study 2 13 Discussion Points Concept of IP Subnetting –Three Level Subnet Hierarchy Network Prefix, Subnet-Number, Host-Number Subnet structure not visible to external Internet The routers within the internal network need to differentiate between individual subnets Internet routers, all subnets within internal networks collected into a single routing table entry Route Flapping –Subnet Address Mask

14. CSE5807 - Case Study 2 14 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
