basic ipv6 networking : newbie's questions
« on: August 06, 2009, 10:22:53 AM »

This newbie still got plenty a questions  ::)

H.E. gave me a tunnel, with 2 IPv6 networks viz

2001:470:1F12:1E7::2 (I guess this is a point-to-point network between me and HE), I can use only 1 IP out of this /64, right ?

2001:470:1F13:1E7::/64 -> this one is for me to do whatever I fancy, right ?

My Windows (2k) networking question : I've assigned my test machine itself an address from the /64 in addition to the point to point address. No IPv6 routing is done in my machine or local network.
when I browsed to <www.whatismyipv6.com> it showed the new address as a source.
Well, how come the browser selected that second, fancy, address as a source ?

What IP should I use normally for the machine connected to the tunnel, the ppp one or one out of the "private" /64 ?

How did this work in my case, despite I haven't set up anything to route between the two /64s ?

Finally, what is a recommended /light/ software IPv6 router that can run on Win 2k ?

Instead, will my SuSE 9.1 linux machine be a capable ipv6 router out of the box ?

Thanks in advance for your patience...

Addresses:  Correct.

What addresses on the tunnel machine:
- The tunnel interface gets the ::2 in the tunnel /64.
- Some other interface (usually ethernet) gets a routed /64 allocation.

Linux will IPv6 route, but it may need recompilation to turn on certain features.

I'm not a SUSE person, I'm a CentOS person but it took only a few minutes to setup the tunnel on a CentOS 5 box.

On the tunnel page, at the bottom pick your OS (Linux in this case) and it shows an example of how to setup the tunnel.

Confirm your tunnel works (ping an IPv6 site like tunnelbroker.net), if it works install RADVD

Here's my config file..

/etc/radvd.conf

Code: [Select]
# NOTE: there is no such thing as a working "by-default" configuration file.
#       At least the prefix needs to be specified.  Please consult the radvd.conf(5)
#       man page and/or /usr/share/doc/radvd-*/radvd.conf.example for help.
#
#
interface eth0
{
        AdvSendAdvert on;
        MinRtrAdvInterval 30;
        MaxRtrAdvInterval 100;
        prefix 2001:????:????:????::/64
        {
                AdvOnLink on;
                AdvAutonomous on;
                AdvRouterAddr off;
        };

};

Replace the 2001:????:????:????::/64 with your tunnel IP.
