Detailed explanation-1: -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: -All interfaces on IPv6 nodes must have a link-local address, which is automatically configured from the identifier for an interface and the link-local prefix FE80::/10. A link-local address enables a node to communicate with other nodes on the link and can be used to further configure the node.
Detailed explanation-3: -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-4: -Ensure that you have completed the required prerequisites before you begin IPv6 configuration. Configure a router. Configure tunnel interfaces on the router. Configure the switches on the network. Configure any hubs on your network. Configure the network name service for IPv6. More items
