Troubleshoot a faulty computer network : RIP Troubleshooting Scenario 1. Can you find the issue?

The video tutorial covers troubleshooting a network issue where router one cannot ping the loopback of router four. It begins with verifying the problem and proceeds with debugging steps to identify the source of the issue. The problem is traced to incorrect IP address configurations on routers, which are then corrected. The tutorial concludes with verifying the solution and ensuring network connectivity is restored.

What is the initial problem identified in the network?

• Router 1 cannot ping the loopback of Router 4.

• Router 2 cannot ping the loopback of Router 3.

• Router 3 cannot ping the loopback of Router 1.

• Router 4 cannot ping the loopback of Router 2.

What command is used to check if the local router has a gateway of last resort set?

• traceroute

• show ip protocols

• show ip route

• debug ip packet

What was the main issue causing Router 2 to ignore updates from Router 3?

• Incorrect subnet mask

• Disabled RIP protocol

• Incorrect routing table

• Bad source IP address

Which command is used to verify the IP address configuration on a router?

• debug ip rip

• show ip protocols

• show ip route

• show ip interface brief

What was the solution to the network problem?

• Correcting the IP address configurations

• Enabling RIP on all interfaces

• Setting a gateway of last resort

• Disabling IP domain lookup

After resolving the issue, which network was successfully learned by the routers?

• Network 10.1.3.0

• Network 10.1.4.0

• Network 10.1.2.0

• Network 10.1.1.0

What is the importance of routers being in the same subnet?

• To disable debugging

• To enable IP domain lookup

• To exchange routing updates

• To set a gateway of last resort
