TAILIEUCHUNG - Lab 4.2.5b Connectivity Tests – Traceroute

The traceroute command, abbreviated as trace, is an excellent utility for troubleshooting the path that a packet takes through an internetwork of routers. It can help to isolate problem links and routers along the way. The traceroute command uses ICMP packets and the error message generated by routers when the packet exceeds its Time-To-Live (TTL). The Windows version of this command is tracert. | Cisco Systems I Lab Connectivity Tests - Traceroute Router designation Router Name Enable secret password Enable VTY and console password Routing protocol RIP network statements Router 1 GAD class Cisco RIP Router 2 BHM class Cisco RIP Router designation IP host name Fast Ethernet 0 address Interface type Serial 0 Serial 0 address Interface type Serial 1 Serial 1 address Subnet mask all addresses Router 1 GAD DCE NA No address Router 2 BHM DTE NA No address Straight-through cable Serial cable Console Rollover Crossover cable Objective Use the traceroute Cisco IOS command from source router to destination router. Use the tracert MS-DOS command from source workstation to destination router. Verify that the network layer between source destination and each router along the way is working properly. Retrieve information to evaluate the end-to-end path reliability. Determine delays at each point over the path and whether the host can be reached. Background Preparation The traceroute command abbreviated as trace is an excellent utility for troubleshooting the path that a packet takes through an internetwork of routers. It can help to isolate problem links and routers along the way. The traceroute command uses ICMP packets and the error message generated by routers when the packet exceeds its Time-To-Live TTL . The Windows version of this command is tracert. Setup a network similar to the one in the previous diagram. Any router that meets the interface requirements may be used. Possible routers include 800 1600 1700 2500 2600 routers or a combination.
