The video covers a detailed walkthrough of troubleshooting and restoring network connectivity in a CCNA version 7 packet tracer activity using both IPv4 and IPv6 protocols. Key themes addressed include configuring and verifying correct IP configurations, identifying and resolving connectivity issues using commands like `ipconfig /all`, `ping`, and `traceroute`, and working with multiple network devices such as PCs and routers (R1, R2, R3).
Important procedures include filling out an addressing table with correct IP details, tracing routes to pinpoint where the connectivity breaks, and configuring routers to display their connected networks using `show IP route` and `show IP interface brief` commands. Special attention is given to both IPv4 and IPv6 configurations, including correcting incorrect IP assignments on interfaces and ensuring proper default gateway settings.
Ultimately, the video emphasizes practicing these troubleshooting techniques to debug network issues efficiently, with a final successful demonstration of restored connectivity and a fully completed packet tracer activity. The instruction encourages engagement through comments and visits to their website for more technical content.

In this segment of the video, the focus is on a CCNA version 7 packet tracer activity, specifically using ping and traceroute to test network connectivity. The segment begins by encouraging viewers to subscribe for more technical content and provides information on how to contact the team. The activity involves completing an addressing table, which currently has missing IP address details for several PCs and default gateway information. The goals are to test and restore both IPv4 and IPv6 connectivity by identifying and solving any connectivity issues.
The instructions provided include using the `ipconfig /all` command on PC-1 to collect IPv4 information, such as the IP address, subnet mask, and default gateway. These details are then documented in a spreadsheet to update the network addressing table. The video demonstrates how to navigate to the command prompt on PC-1 and execute the command to retrieve and copy the necessary IP configuration details.
00:03:00
In this part of the video, the instructor demonstrates how to troubleshoot network connectivity issues by using the command prompt on PC3. They start by collecting IPv4 information via the “ipconfig /all” command to fill out an addressing table with the IP address, subnet mask, and default gateway. After obtaining these details, they use the “ping” command from PC1 to test connectivity to PC3, which fails as expected. Following this, they perform a traceroute from PC1 to identify where the connectivity failure occurs. The traceroute shows that the last successful IP address accessed was 10.10.1.97 before timing out.
00:06:00
In this part of the video, the presenter demonstrates how to trace the route from one PC to another. Initially, they explain that the trace will attempt up to 30 times but can be stopped using Ctrl+C. They perform a traceroute from PC 3 to PC 1, identifying the last successful IPv4 address. Following this, they log into router R1, use the “show IP interface brief” command to list interface statuses, and identify the IP addresses. They note specific IPs for Gigabit Ethernet and Serial interfaces and refer back to the traced route results.
00:09:00
In this part of the video, the presenter demonstrates how to use various network commands to gather details about router connections. They start by configuring router R1 to display its connected networks using the `show IP route` command, revealing two networks connected to the serial 0/0/1 interface. Then, they switch to router R3, where they log in and use the `show IP interface brief` and `show IP route` commands to list its interfaces and connected networks. They identify IP addresses and the status of connections on R3, mentioning that two networks are connected to its serial 0/0/1 interface.
00:12:00
In this segment, the speaker is working on a router (R2) and identifies that the IP address for interface serial “0/0/0” is configured incorrectly. They suggest verifying the IP addresses using the “show IP interface brief” command and comparing it against the network documentation. To correct the issue, they propose reassigning the IP address according to the addressing table. The speaker then proceeds to implement this solution by copying the correct IP address from the table and configuring it on the R2 interface through the terminal.
00:15:00
In this segment of the video, the instructor is guiding through the process of verifying network connectivity between PCs using ping and tracer commands. Initially, they verify IPv4 connectivity by instructing to ping from PC1 to PC3 and vice versa, confirming successful communication. They then move on to testing and restoring IPv6 connectivity by using the `ipv6 config /all` command to collect necessary IPv6 information, including the address, subnet prefix, and default gateway. This information is then entered into a spreadsheet for reference. Finally, they suggest repeating the process on PC4 to collect similar IPv6 details.
00:18:00
In this part of the video, the instructor demonstrates how to troubleshoot IPv6 connectivity issues between two PCs using command prompt tools. First, they configure and check the IPv6 address on PC4, copying the details into a spreadsheet. The instructor then attempts to ping PC4 from PC2, but the ping fails. Next, they use the `tracert` command on PC2 to trace the route to PC4’s IPv6 address. The trace shows the last successful hop before timing out, indicating the point of failure. The instructor notes that the trace can be stopped manually using “Ctrl+C” before it completes all 30 attempts.
00:21:00
In this part of the video, the presenter demonstrates how to use the traceroute command to trace the route to a PC via its IPv6 address. They identify an issue with the default gateway on PC4 as the trace does not yield an IPv6 address. The presenter then logs into the router (R3), uses the ‘show ipv6 interface brief’ command to list the interfaces and their statuses, and verifies the IPv6 addresses against the expected gateway address. After authentication, they confirm the IPv6 address on the router’s Gigabit and Serial interfaces.
00:24:00
In this part of the video, the speaker addresses an issue with IP configuration on a network device, specifically incorrect configuration of the IPv6 gateway on PC. The gateway should be set to fe80::3, but it was configured as fe80::2. The speaker proposes and implements the solution by correcting the gateway address. They then verify connectivity by pinging between PCs, successfully demonstrating network connectivity using ping and traceroute commands. The completion status of the packet tracer activity reaches 100%.
