Case Study 2 – The Concept of IP Subnetting Network Address 35.0.0.0/18 Subnet 152 Brisbane Router S 2/0 DCE Serial Cable S 2/0 Adelaide Router Fa 0/0 Fa 0/0 UTP Cable Subnet 85 Subnet 92 Bris_Hub Host 262 Bris PC Adel_Hub Adel PC Host 520 CSE5807 - Case Study 2 4
Brisbane Router - Configuration
! The FastEthernet interface configuration: interface fa 0/0 ip address <
replace with address
> 255.255.192.0
description Link to Brisbane Hub, Subnet 85 no shutdown ! The Serial interface configuration: interface serial 2/0 ip address <
replace with 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 CSE5807 - Case Study 2 5
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 CSE5807 - Case Study 2 6
Adelaide Router - Configuration
! The FastEthernet interface configuration: interface fa 0/0 ip address <
replace with address
> 255.255.192.0
description Link to Adelaide Hub, Subnet 92 no shutdown ! The Serial interface configuration: interface serial 2/0 ip address <
replace with address
> 255.255.192.0
description Link to Brisbane Router, Subnet 152 no shutdown ! Set hostname of the router hostname Adelaide CSE5807 - Case Study 2 7
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 CSE5807 - Case Study 2 8
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?

Routing Protocols
Brisbane Router router rip version 2 network <
replace with network address
> Adelaide Router router rip version 2 network <
replace with network address
> CSE5807 - Case Study 2 10
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?

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 CSE5807 - Case Study 2 12
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 CSE5807 - Case Study 2 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 CSE5807 - Case Study 2 14
