How can I install IPv6

[Raphael Lee]

Hello. This is Raphael Lee.
I'm a student of ICU in Korea.
I have a question about router setup a INRIA IPv6 router for FreeBSD 2.2.5.
first rc.ipv6 file options..(It is rc.ipv6-duvel)


# IPv6 setup for duvel{-v6.ipv6}.inria.fr (FreeBSD 2.2.5)
 autoconf6 -v >/tmp/autoconf6 2>&1 &
 cat /home/dupont/cache.au > /dev/audio

#else
# sysctl net.inet6.ipv6.multi_homed
#
# ifconfig de0 inet6 fe80::220:feff:fe00:8781/128
# route -n add -iface -inet6 ff02::/16 fe80::220:feff:fe00:8781
# route -n add -iface -inet6 ff12::/16 fe80::220:feff:fe00:8781
#
# ifconfig fpa0 inet6 fe80::a00:2bff:feb4:8ff3/128
#
# ifconfig ll0 inet6 fe80::220:feff:fe00:8781/64
#
# ifconfig sit0 inet6 ::128.93.9.50/96
# ifconfig sit1 inet6 ::193.51.193.60/123
#
# ifconfig lo0 inet6 ::1/128
# route -n add -inet6 ff01::/16 -iface ::1
# route -n add -inet6 ff11::/16 -iface ::1
# route -n add -iface -cloning -inet6 ::/0 fe80::220:feff:fe00:8781
#fi

# eui64 magic option can easily used here!

ifconfig de0 inet6 firstalias 3ffe:0306:1051:8300::/64 eui64
ifconfig fpa0 inet6 firstalias 3ffe:0306:1051:d6d2::/64 eui64
->  What is a prefix of router duvel?
     and.. where do I write my prefix for route?
-> why 2 prefix exist?
-> What is magic option? comment file is written by French..
   (sorry.. I can't speak french..   !_! )

# route to 6bone via a configured tunnel
#(cticonfig -v -4 -l -s 128.93.9.50 cti0 129.88.26.1;
# cticonfig -v -4 -s 128.93.9.50 cti1 192.44.68.18) >/tmp/cticonfig 2>&1
#
#ifconfig cti0 inet6 3ffe:0306:1051:8300:1:0:805d:932/128 ::129.88.26.1
#
#ifconfig cti1 inet6 firstalias 3ffe:0306:1051:8300:1:0:805d:932/128
::192.44.68.18

- > Is it tunnel for connection to 6bone from duvel?
    what is duvel? and.. what is 6bone connection point?

#route -n add -inet6 ::/0 ::129.88.26.1
#route -n add -inet6 3ffe:306:1051:d6d0::/60 fe80::240:bff:fe40:94bb -ifa
3ffe:0306:1051:d6d2:a00:2bff:feb4:8ff3

# turn IP forwarding on

sysctl -w net.inet6.ipv6.forwarding=1
sysctl -w net.inet6.ipv6.mforwarding=1
#ndpd-router -s -g
ndpd-router -s


and.. 1. 'make world in /usr/src/', 2. kernel compile,
3. update rc.ipv6 file.
are all methods  to setup router?

My IPv6 machine is not works in above methods..
I guess... ... inetd.conf or rc.conf file has to fix ?
how?

Bye...
