There is a difference between "what I need to type after the system is
up" and "what I need to add to rc.conf so that the boot scripts
understand what I'm trying to do." Read the rc.conf man page, and
particularly the ipv6_network_interfaces entry.

You can't have a default route for an interface that isn't up, and you
can't do IPv6 at boot without ipv6_enable, so yes, both are required.
