Which command is used to verify the IPv6 configuration on a Cisco device?

The command used to verify the IPv6 configuration on a Cisco device is "show ipv6 interface." This command provides detailed information about the IPv6 settings and status for all interfaces on the device. It allows network administrators to check various aspects of IPv6 configuration such as the IPv6 address assigned to each interface, the status of the interface (up or down), and the link-local address, among other details.

For anyone managing a Cisco device, understanding the "show ipv6 interface" command is crucial because it offers insights into whether IPv6 is functioning correctly on the device. This includes confirming proper address assignments and troubleshooting any issues related to IPv6 communication on the network.
