What command will enable a router to begin sending messages that allow it to configure a link-local address without using an IPv6 DHCP server?
- a static route
- the ipv6 route ::/0 command
- the ipv6 unicast-routing command
- the ip routing command
Explanation: To enable IPv6 on a router you must use the ipv6 unicast-routing global configuration command or use the ipv6 enable interface configuration command. This is equivalent to entering ip routing to enable IPv4 routing on a router when it has been turned off. Keep in mind that IPv4 is enabled on a router by default. IPv6 is not enabled by default.
