Description : This lab demonstrates the steps required to enable ipv6 on a cisco router.
1. Enter into privileged mode on router R1.
2. Enter into global configuration mode.
3. Enter the command "ipv6 unicast-routing" that enables the forwarding of IPv6 unicast datagrams globally on the router.
Note: The first step of enabling IPv6 on a Cisco router is the activation of IPv6 traffic forwarding to forward unicast IPv6 packets between network interfaces. By default, IPv6 traffic forwarding is disabled on Cisco routers.
The ipv6 unicast-routing command is used to enable the forwarding of IPv6 packets between interfaces on the router.
