Detailed explanation-1: -28. What is the minimum configuration for a router interface that is enabled for IPv6? With IPv6, a router interface typically has more than one IPv6 address. The router will at least have a link-local address that can be automatically generated, but the router commonly has an global unicast address also configured.
Detailed explanation-2: -Enable IPv6 routing on a Cisco router using the ipv6 unicast-routing global configuration command. This command globally enables IPv6 and must be the first command executed on the router. Configure the IPv6 global unicast address on an interface using the ipv6 address address/prefix-length [eui-64] command.
Detailed explanation-3: -IPv6 Network Addresses The first hextet has a range of 1111 1110 1000 0000 (FE80) to 1111 1110 1011 1111 (FEBF). Note: Typically, it is the link-local address of the router and not the global unicast address that is used as the default gateway for other devices on the link.
