To use IPv6 on your router, you must, at a minimum, enable the protocol and assign IPv6 addresses to your interfaces.

The correct answer to the question "What is one requirement for interfaces to run IPv6?" is A. An IPv6 address must be configured on the interface.

IPv6 is the latest version of the Internet Protocol and is designed to provide a larger addressing space, improved security, and better support for mobile devices. In order for interfaces to run IPv6, they must meet certain requirements. One of the primary requirements is the need for an IPv6 address to be configured on the interface.

IPv6 addresses are 128 bits long and are written in hexadecimal notation. They are typically represented using eight groups of four hexadecimal digits, separated by colons. For example, a valid IPv6 address might look like this: 2001:0db8:85a3:0000:0000:8a2e:0370:7334.

To configure an IPv6 address on an interface, you must first enable IPv6 on the interface. This is typically done using the "ipv6 enable" command in global configuration mode. Once IPv6 is enabled on the interface, you can configure an IPv6 address using the "ipv6 address" command in interface configuration mode.

For example, to configure an IPv6 address of 2001:db8::1/64 on interface GigabitEthernet0/0, you would use the following commands:

Router(config)# interface GigabitEthernet0/0 Router(config-if)# ipv6 enable Router(config-if)# ipv6 address 2001:db8::1/64

It is also important to note that interfaces running IPv6 may also require other configurations or settings, such as enabling stateless autoconfiguration or configuring routing protocols. However, the presence of an IPv6 address on the interface is a fundamental requirement for running IPv6.
