Questa pagina è inviata in inglese a causa della sua indisponibilità in vostra lingua selezionata Syntax of Configuration IPv6 * BSD
FreeBSD
that which you need :
FreeBSD 4.x compiled with support INET6 (it is activated by défault on kernel GENERIC)
the points of interconnection IPv4 and IPv6. will note we them this way :
lanv4 - youre address IPv4
lanv6 - youre address IPv6
distv4 - the distant address IPv4
distv6 - the distant address IPv6
Installation :
no necessary installation (the system is allready ok for ipv6)
Tunnel configuration
do not forget to replace gifx by gif0 or other according to your OS
you must execute these commands in SU or ROOT
# gifconfig gifx lanv4 distv4
# ifconfig gifx inet6 lanv6 distv6 prefixlen 128
the tunnel must be now activated one test if the distant access point answers
% ping6 distv6
PING6(56=40+8+8 bytes) lanv6 --> distv6
16 bytes from distv6, icmp_seq=0 hlim=64 time=15.312 ms
16 bytes from distv6, icmp_seq=1 hlim=64 time=14.652 ms
16 bytes from distv6, icmp_seq=2 hlim=64 time=15.057 ms
it's working ;)
Routing configuration
in the most of the cases, there will be just a road by default has destination of the waiter of tunnel
# route add -inet6 default distv6
or
# route add -inet6 default -interface
gifx
now you must be capable of ping no matter whom, eg ping6 ipng.ipng.nl (3ffe:8114::1)
if you want only router one small beach by this tunnel (eg a static road) it is very easy
you must route 3ffe:80e8:d8::/48 by gifx
# route add -inet6 3ffe:80e8:d8:: -prefixlen
48 distv6
or
# route add -inet6 3ffe:80e8:: -prefixlen
48 -interface gifx
you want delegate bloc ?
it is also easy. do not forget to return all the data in the base of data of the 6BONE !
http://whois.6bone.net/
you've youre bloc 3ffe:80e8:d8::/48 and you want delegate 3ffe:80e8:d8:8000::/64
by a tunnel on gifx
- To configure the tunnel
- routing the bloc on the tunnel
# route add -inet6 3ffe:80e8:d8:8000::
-prefixlen 64 distv6
or
# route add -inet6 3ffe:80e8:d8:8000::
-prefixlen 64 -interface gifx
Final script :
gifconfig gif0 lanv4 distv4
ifconfig gif0 inet6 lanv6 distv6 prefixlen 127
route -n add -inet6 default distv6
Final script : FreeBSD 4.4
under FreeBSD 4.4 it is not any more nécéssaire of recompiler the core for acceder with
the interfaces gifX, it is from now on possible of the creer has the flight.
ifconfig gif0 create
gifconfig gif0 lanv4 distv4
ifconfig gif0 inet6 lanv6 distv6 prefixlen 127
route -n add -inet6 default distv6
if you have error messages of neighbor discovering
(/kernel: nd6_lookup: failed to add route for a neighbor([youre_ipv6_cote_tb]), errno=17)
try the parameter prefixlen 128 this is not abnormal
To add a ipv6 on your interface LAN :
ifconfig [interface] inet6 [ipv6] prefixlen [longueur de prefix] alias
Examples :
ifconfig xl0 inet6 3FFE:1200:3028:84ef::1 prefixlen 64 alias
ifconfig xl0 inet6 3FFE:1200:3028:84ef::5 prefixlen 64 alias
ifconfig xl0 inet6 3FFE:1200:3028:84ef::53 prefixlen 64 alias
ifconfig xl0 inet6 3FFE:1200:3028:84ef::54 prefixlen 64 alias
ifconfig xl0 inet6 3FFE:1200:3028:84ef::80 prefixlen 64 alias
ifconfig xl0 inet6 3FFE:1200:3028:84ef::6667 prefixlen 64 alias
NetBSD
Official documentation :
http://www.netbsd.org/Documentation/network/ipv6/
OpenBSD
patch setup :
no setup required (the system is already ready for ipv6)
script :
ifconfig gif0 giftunnel [youre_ipv4_public] [ipv4_of_tunnel_broker]
ifconfig gif0 inet6 [youre_ipv6_public] [youre_ipv6_side_tb] prefixlen 127
route -n add -inet6 default [youre_ipv6_side_tb]
Router
To make to your machine a IPv6 router there exists several solutions/softs
1) to use the standard configuration
add in /etc/rc.conf
ipv6_enable="YES"
(incomplete part)
2) Using sysctl
sysctl -w net.inet6.ip6.forwarding=1 #for enabling routing IPV6
(to make has each boot)
3) By Soft (radvd rtadvd or zebra)
