In this article we will discuss CCNA 184.108.40.206 Packet Tracer – Troubleshooting Default Gateway Issues, will make brief discussion on Troubleshooting Default Gateway Issues. In last article we discuss about Default Gateway for a Host – Network Gateway.
Background of 220.127.116.11 Packet Tracer – Troubleshooting Default Gateway Issues
Background of 18.104.22.168 Packet Tracer – Troubleshooting Default Gateway Issues, For a device to communicate across multiple networks, it must be configured with an IP address, subnet mask, and a default gateway. The default gateway is used when the host wants to send a packet to a device on another network. The default gateway address is generally the router interface address attached to the local network to which the host is connected. In this activity, you will finish documenting the network.
Part 1: Verify Network Documentation and Isolate Problems
In Part 1 of this activity, complete the documentation and perform connectivity tests to discover issues. In addition, you will determine an appropriate solution for implementation in Part 2.
Step 1: Verify the network documentation and isolate any problems.
Before you can effectively test a network, you must have complete documentation. Notice in the Addressing Table that some information is missing. Complete the Addressing Table by filling in the missing default gateway information for the switches and the PCs. Test connectivity to devices on the same network. By isolating and correcting any local access issues, you can better test remote connectivity with the confidence that local connectivity is operational. A verification plan can be as simple as a list of connectivity tests. Use the following tests to verify local connectivity and isolate any access issues. The first issue is already documented, but you must implement and verify the solution during Part 2.
Step 2: Determine an appropriate solution for the problem.
Using your knowledge of the way networks operate and your device configuration skills, search for the cause of the problem. For example, S1 is not the cause of the connectivity issue between PC1 and PC2. The link lights are green and no configuration on S1 would cause traffic to not pass between PC1 and PC2. So the problem must be with PC1, PC2, or both. b. Verify the device addressing to ensure it matches the network documentation. For example, the IP address for PC1 is incorrect as verified with the ipconfig command. c. Suggest a solution that you think will resolve the problem and document it. For example, change the IP address for PC1 to match the documentation. Note: Often there is more than one solution. However, it is a troubleshooting best practice to implement one solution at a time.
Part 2: Implement, Verify, and Document Solutions
In Part 2 of this activity, you will implement the solutions you identified in Part 1. You will then verify the solution worked. You may need to return to Part 1 to finish isolating all the problems.
