Native connection ADSL in IPv6

Nerim is the first ISP in France to place at the disposal of its subscribers an access ADSL in IPv6.

• To have a Nerim subscription with address IP(v4) fixed.
• The machine connected to the ADSL must support connections PPP in IPv6. A router under GNU/Linux or FreeBSD or a material router (Cisco or 6Wind for example) can agree. A machine under Windows is not compatible, the routeurs/modem provided by Nerim in its packs either (except if they are configured out of simple modem).

• An IPv6 Bloc
  • The block of IP allocated with the tunnel is not the same one as that that you will have as a native, it is necessary thus new for you
  • the form should be used to know your new block below
  • For reverses DNS it is necessary to make the request of it with dns@nerim.net

Form of attribution of the IPv6 block /48

Lastly, it is necessary to configure your IPv6. As for the moment there is no stable protocol automatically to parameterize the /48 of the customer, it is necessary for you to know your IP. With this intention, indicate in this box your fixed IPv4 address. If you have a block of IP, give the external address of the router, that which does not form part of the block.

It should first of all be configured its router so that it negotiates connection in IPv6.

If connection occurs well, you will have on interface PPP IPv6 an address known as "link local", who resembles something like that : fe80::545c:ba9b:1c8c:ef/10.
(Warning : FreeBSD before to 4.7 dregs a address local bond on the interfaces tunX by defect but does not support therefore IPv6 via PPP)
If you arrive at this point, you are on the good way.

• RP-PPPoE
  • Add in the pppoe.conf :
    

    	PPPD_EXTRA="ipv6 ,"	

  • Except in the case of the red hat 8 which dynamically generate the pppoe.conf in this case it should be put here :
    

    	/etc/sysconfig/network-scripts/ifcfg-ppp0

• FreeBSD 4.7 and later
  • There is nothing has to make has share to put its new login and the route by default
  • the route :
    

    	route add -inet6 default -interface tun0

• OpenBSD
  • PPPoE
    • the route in /etc/ppp/ppp.conf :
      

      	add default HISADDR6	

  • PPTP
    • It is necessary to update PPP since this page : PPP IPv6 FreeBSD. in the /etc/ppp/ppp.conf :
      

      noauth
      noipdefault
      defaultroute
      debug
      ipv6 ,
      name "login@net1.nerim.nerim"
      add default HISADDR6
      

• NetBSD (tested by Manuel Bouyer)
  • There is nothing has to make has to put its new login and the road by default
  • (in /etc/ifconfig.pppoe0)
    

    	inet6 (one addresse of the /48)
    	!route add -inet6 default (address chosen with the top)

• GNU/Linux
  • All
    • It is necessary on the one hand to check that pppd is compiled with the IPv6 support and to add the following line in the file of configuration PPP /etc/ppp/options :
      

      	ipv6 ,

      (The comma must be present). This is valid for all the Linux distributions
  • USAGI
  • route add -A inet6 default ppp0
  • NOT USAGI
  • route add -A inet6 ::/0 ppp0
  • (ALTERNATIVE)
  • ip -f inet6 route add 2000::/3 dev ppp0 metric 1
• Cisco
  • (in the dialer)
    • ipv6 enable
no ipv6 nd suppress-ra
ipv6 route ::/0 dialer 0

For the other routers material, to refer to their documentation and information of this paragraph.

OTHER INFORMATIONS

To make sure that PPP supports IPV6CP (BSD)

OS List functional or not :

OS	IPV6CP (Point to Point Protocol)
FreeBSD	YES
OpenBSD	YES
NetBSD	YES
Solaris	YES
Linux	YES
Windows 9x	NO
Windows 2000	NO
Windows XP	NO
Windows 2003	NO

Connection by tunnel

If Nerim cannot provide you native IPv6 connection, there remains the possibility of configuring a tunnel. With this intention, send a mall to ipv6@nerim.net by specifying your name, your login ADSL and IPv4 or it is necessary to provide the tunnel. Under 8 days, you will receive the parameters of the tunnel.
