Explanation

The command ipv6 unicast-routing (C) enables IPv6 routing (forwarding) globally on a Cisco router. By default, a Cisco router does not forward IPv6 packets - this global configuration command must be entered first. Without it, the router will not route IPv6 traffic between interfaces, even if IPv6 addresses are configured on those interfaces. The other options (ipv6 local, ipv6 host, ipv6 neighbor) are not valid global IPv6 routing commands.
