Testing end-to-end connectivity
After configuring and verifying your IPv6 configurations, the last thing a professional must always do is test end-to-end network connectivity between devices.
On our router, let's test the connection between the router and the computer on our topology using the ping command:
Figure 3.54 – Ping results on Cisco IOS
As you can see, we got five exclamation marks (!). This means we have successful replies from the PC. Receiving a dot (.) means Request Timeout, while U means destination unreachable on the Cisco IOS. If you are not getting a successful connection, double-check your configurations and ensure the cables are connected to the configured interfaces on each device.
