Answer 1

Lab 47's task involves troubleshooting a network in an IPv6 environment by pinging between computers, identifying connectivity issues, and correcting them using show commands and manual configuration adjustments.

Step-by-step explanation:

The purpose of Lab 47 is to troubleshoot a network setup in an IPv6 environment. During the troubleshooting process, one might carry out the following steps:

• Open the IPv6_Troubleshooting.pkt file and attempt to ping from PC1 to both PC2 and PC3.
• Observe the results to identify any anomalies or lack of connectivity which could indicate an issue with the network topology.
• Utilize various show commands on network devices to gather more information about interfaces, routes, and neighbor discovery statuses, etc.
• Based on the findings, determine if there are any incorrect settings such as mismatched subnet addresses, incorrect gateway settings, or improper interface configuration.
• Apply necessary fixes to the network configuration based on the observed problems. This might involve adjusting the IP addresses, subnet masks, and ensuring that the routing tables are correct.

After performing these adjustments, re-test the connectivity by pinging from PC1 to PC2 and from PC1 to PC3. If the issues have been properly addressed, the pings should now be successful.

Note that the assignment specifically states not to use auto configuration to resolve the problems, so manual configuration adjustments should be applied.

Answer 2

In IPv6 troubleshooting scenarios, if there's an issue with communication

Check IPv6 Addresses: Verify that each device has a valid IPv6 address configured in the correct subnet.

Confirm Default Gateway: Ensure that each device has the correct IPv6 default gateway set. Misconfigured gateways can prevent proper communication.

Verify Connectivity: Use ping commands between devices to check if there's connectivity. For example, from PC1, try pinging

Check Router/Device Configuration: Review router/device configurations for proper IPv6 settings, including routing, interface configurations, and neighbor discovery protocols.

Inspect Firewall or Security Settings: Sometimes, firewall rules or security settings can

Use 'show' Commands: Use relevant 'show' commands on routers and switches to inspect IPv6-related set

To answer your lab questions, observe any issues preventing ping communications, identify the obvious problem
