No, it for safety.

wvhemel> Ok, that seems logical.
It seems you don't want to use Play&Play of IPv6. In this case, you
don't need to run rtadvd at all. It is a server for providing
Plag&Play.

I see.
wvhemel> How would you go about if you would make a static route for each host?
Yes, if you don't use Plag&Play of IPv6, you need to install static
route to each host.
wvhemel> That would be possible, no?
Yes, you can with something like:
route add -inet6 default link-local-address-of-router%interface-of-the-host
When you use rc.conf, you can put something like:
ipv6_defaultrouter="fe80::220:afff:fef8:7c44%de0"
I you choose to use Plag&Play, default route will be installed
automatically by invoking rtsol for end host.
wvhemel> Allow me to explain what I want (if possible) and don't know how to
wvhemel> achieve. I'd like to make the ip as short as possible, and appoint
wvhemel> 3ffe:b80:1c8::1 to 192.168.196.1, 3ffe:b80:1c8::2 to 192.168.196.2, and so
wvhemel> on.
I understand your needs.
wvhemel> Just to make sure, for the other machines, I just add something like
wvhemel> '3ffe:b80:1c8::2' to ed1 with ifconfig?
Yes, you can. However, you cannot use Plug&Play of IPv6 in this case.
When you use rc.conf, you can put ipv6_ifconfig_* instead of
ipv6_prefix_*.
