The video is a detailed instructional guide on completing a Packet Tracer activity for the CCNA Version 7 certification, focusing on testing and troubleshooting network connectivity using IPv4 and IPv6 addresses. The presenter walks through the processes of configuring IP addresses, using command-line tools like `ipconfig`, `ping`, and `tracert` to verify and diagnose connectivity issues among multiple PCs and routers (R1, R2, R3). Key points include correcting IP address misconfigurations, setting appropriate default gateways, and ensuring proper subnet masks. Emphasis is placed on accurately recording network details into an addressing table and solving connectivity problems through step-by-step troubleshooting methods. The video concludes with the successful establishment of full network connectivity and an invitation for viewer interaction and feedback.

In this segment of the video, the presenter discusses a CCNA Version 7 Packet Tracer activity focusing on using ping and traceroute to test network connectivity. The addressing table provided is incomplete, with missing details for multiple PCs and a router’s default gateway. The primary objectives are to test and restore both IPv4 and IPv6 connectivity by identifying and resolving connectivity issues. The presenter mentions the user and privileged exit passwords (‘cisco’ and ‘class’, respectively) and proceeds to explain the instructions for verifying IPv4 connectivity. Specifically, they show how to use the IP config and ping commands on PC 1 to collect and fill in the necessary IPv4 information, including the IP address, subnet mask, and default gateway, into an addressing table.

In this part of the video, the instructor demonstrates how to configure and test network settings using command prompt commands on PC3. They open the command prompt and enter “ipconfig /all” to gather the IPv4 information, including the IP address, subnet mask, and default gateway, which they then record in the addressing table. Next, they use the ping command from PC1 to test connectivity to PC3, which results in failure with a “destination host unreachable” message. The instructor then proceeds to troubleshoot the connectivity issue by using the “tracert” command on PC1 to trace the route to PC3. They observe that the last successful IPv4 address reached is 10.10.1.97 before timeouts occur.
00:06:00
In this part of the video, the presenter discusses the process of performing a traceroute command from PC 3 to PC 1 and identifying the last successful IPv4 address in the route. They demonstrate stopping the trace using `Ctrl + C` and provide the specific IP address being traced. The presenter then logs into router R1 using the command line interface, entering the password and enabling access. They execute the `show IP interface brief` command to list the router’s interfaces and their statuses, highlighting two specific IPv4 addresses on the router, with emphasis on one recorded in a previous step. They conclude by confirming the IP address details seen during the traceroute.
00:09:00
In this part of the video, the presenter focuses on configuring and analyzing the IP interfaces of routers R1 and R3. For router R1, the presenter uses the “show IP” command to list the connected networks to the interface serial 0/0/1, identifying two connected networks: 10.10.1.4/30 and 10.1.6/32. The steps are then repeated for router R3, where the “show IP interface brief” command is used to display the IP addresses and statuses of interfaces, including gigabitEthernet 0/1 and serial 0/0/1. For router R3, the network 10.10.5.3 is identified, and the “show IP route” command reveals two connected networks: 10.1.8/30.
00:12:00
In this part of the video, the speaker addresses troubleshooting an incorrectly configured IP address on router R2. The IP address for the interface serial 0/0/0 is observed to be set incorrectly. The solution proposed involves correcting the IP address according to the addressing table. The speaker guides how to implement this solution by logging into the router, accessing the terminal, navigating to the specific interface, and reassigning the correct IP address.
00:15:00
In this part of the video, the steps to verify network connectivity between PCs are demonstrated. First, the user assigns a subnet mask and then verifies connectivity by pinging between PC1 and PC3: PC1 successfully pings PC3 and vice versa. Next, IPv6 connectivity is tested. The user accesses the command prompt on PC2 to retrieve IPv6 configuration details, including the IPv6 address, subnet prefix, and default gateway. This information is then copied into a spreadsheet. Similar steps are to be followed for other PCs to ensure complete network setup and testing.
00:18:00
In this segment of the video, the instructor moves to PC 4’s command prompt, checks its IPv6 configuration, and copies the IPv6 address and default gateway into a spreadsheet. Next, they test connectivity between PC 2 and PC 4 by pinging PC 4’s IPv6 address from PC 2, which fails, indicating a connectivity issue. To diagnose this, they use the `tracert` command from PC 2 to trace the route to PC 4, identifying the last successful IPv6 address before the trace times out. The process demonstrates troubleshooting steps for connectivity issues using command-line tools.
00:21:00
In this segment, the presenter demonstrates how to trace the route to a specific PC using an IPv6 address. They begin by accessing the command prompt on a PC and use the “tracert” command to initiate the trace. However, the trace results in a timeout, leading the presenter to suspect an issue with the default gateway on the device. To diagnose this, they stop the trace and log into a router (R3), using the “show ipv6 interface brief” command to check the router interfaces and their status. They verify the IPv6 addresses to identify any discrepancies and confirm the correctness of the addresses, specifically noting the link-local address and the address associated with a specific interface.
00:24:00
In this part of the video, the speaker identifies an issue with the IPv6 gateway configuration on PC 4, where it is incorrectly set to “fe80::2” instead of “fe80::3.” The proposed solution is to correct the gateway address to “fe80::3.” After implementing this change, the speaker verifies connectivity by pinging between PC 2 and PC 4, confirming that the problem is resolved. The completion status of the task is shown to be 100%.
