Brisbane Router - Configuration
! The FastEthernet interface configuration:
interface fa 0/0ip address <replace with address> 255.255.192.0description Link to Brisbane Hub, Subnet 85no shutdown
! The Serial interface configuration:
interface serial 2/0ip address <replace with address> 255.255.192.0! This is DCE end of the linkclock rate 64000description Link to Adelaide Router, Subnet 152no shutdown
! Set hostname of the router
hostname Brisbane
CSE5807 - Case Study 26
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 27
Adelaide Router - Configuration
! The FastEthernet interface configuration:
interface fa 0/0ip address <replace with address> 255.255.192.0description Link to Adelaide Hub, Subnet 92no shutdown
! The Serial interface configuration:
interface serial 2/0ip address <replace with address> 255.255.192.0description Link to Brisbane Router, Subnet 152no shutdown
! Set hostname of the router
hostname Adelaide
CSE5807 - Case Study 28
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 29
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?
CSE5807 - Case Study 210
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 211
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?
CSE5807 - Case Study 212
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 213
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 214
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
