Title: IPv6 stateless autoconfiguration
Post by: smith21 on October 10, 2011, 07:43:35 AM
hi guys, i get ipv6 run in my network, and now i want to implement stateless autoconfiguration,
may i ask ur kindness to help me with a complete tutorial?

regard

What operating system? You need a system to do Router Advertisements

am running centos, yeah i need the configuration fro RADVD, i tried it but still failed!

interface eth0

{
        AdvSendAdvert on;
        prefix 2001:c08:3700:100::/64
        {
                AdvOnLink on;
                AdvAutonomous on;
                AdvRouterAddr on;
        };

};

i need the complete tutorial for the server as well for the client...

i got one nice tutorial
http://mirrors.bieringer.de/Linux+IPv6-HOWTO/hints-daemons-radvd.html

is it possible to implement through wirelss? because it is written there that it is useful for LAN network? why? what are different between simple conf, special 6to4 conf and debugging? do i need to do some ip calculation for each client?

why it always used prefix /64 while i have two /48 and /64?



Title: Re: IPv6 stateless autoconfiguration
Post by: cholzhauer on October 11, 2011, 04:59:44 AM
Yes, you can use it for wireless too...you just need to change the interface that you're advertising.

You're not running 6to4 with HE, so I wouldn't worry about it

Use the debug setup if you're having issues with your setup

A /64 is the smallest range that most programs will accept, so that's what you're stuck using.  HE gives you a /48 so you can have 64k of /64's (this is needed if you have more than one subnet

You don't need to do any calculation..RA is done for you based off the MAC address of the network adapter.

which interface that's advertising in the net? i still confused about eth0  and eth1
Title: Re: IPv6 stateless autoconfiguration
Post by: cholzhauer on October 11, 2011, 08:22:18 AM
It doesn't like you're using eth0 for anything

eth1 has traffic and a public IP address.

You'll want to assign a IPv6 address to this interface too
Title: Re: IPv6 stateless autoconfiguration
Post by: smith21 on October 11, 2011, 10:03:25 AM
so u mean i shud use eth1?
Title: Re: IPv6 stateless autoconfiguration
Post by: cholzhauer on October 11, 2011, 10:05:27 AM
From what you've shown me, yes. 

It looks like there is a network cable plugged into that interface, but it doesn't look like any traffic is flowing in or out.

hi guys, i need ur help

i got prefix /64 and /48 from HE, but i used /64:
2001:470:xx:xxx::/64

radvd conf:
interface eth2 {
        AdvSendAdvert on;
        MinRtrAdvInterval 3;

X'ing out IP addresses makes it hard to help

You need to assigna IPv6 address to every interface that you want to route/pass IPv6 traffic.  If those interfaces are in different subnets, assign a /64 from your /48 to each subnet

Post by: smith21 on October 13, 2011, 05:20:33 AM
so u mean to conf each computer one by one without making one computer as a router for each clients through stateless conf?
Title: Re: IPv6 stateless autoconfiguration
Post by: cholzhauer on October 13, 2011, 05:34:46 AM
You can either statically assign the addresses or assign via RA

I don't know what you topology is, but if you have something like

internet --- router --- client

you need to put the tunnel ::2 address on the outside interface of the router (and I think you already have) then assign an address from your routed /64 to the inside interface of your router (say its 2001:db8:12:1) then assign another address out of that same subnet to the client behind the router (say 2001:db8:12::2

Post by: smith21 on October 13, 2011, 07:09:52 AM
yes, that my topology is.

is this what u mean?

modprobe ipv6
ip tunnel add he-ipv6 mode sit remote 216.218.221.42 local 202.47.88.67 ttl 255
ip link set he-ipv6 up
ip addr add 2001:470:35:270::2/64 dev he-ipv6
ip route add ::/0 dev he-ipv6
ip -f inet6 addr

what do u mean by inside and outside interface?
Title: Re: IPv6 stateless autoconfiguration
Post by: cholzhauer on October 13, 2011, 07:25:09 AM
the outside interface is what connects to the Internet...inside interface is the interface that connects to the rest of your network
Title: Re: IPv6 stateless autoconfiguration
Post by: smith21 on October 14, 2011, 06:05:30 AM
in this case eth0 is the outside interface and eth2 is the inside interface?

so let say i've to conf eth0:
etc/sysconfig/network-scripts/init.ipv6-global
#server interface configuration
auto eth0
iface eth0 inet6 static
        address 2001:470:36:270::1
        netmask 64

*is it how to conf server?
and for client is wlan0 or what and how to conf it?

I don't know...it depends on how you have your site configured.  If eth0 connects you to the internet, then yes, it's your outside address.

You can configure wlan0 the same way.  If wlan0 is in the same subnet as eth2, use an address  out of the same /64 for both of them.  If wlan0  is in a different network, you'll have to request the /48 from HE and use an separate /64 from that.

It's getting 200:470:36:270::/64 as the prefix from your radvd.conf
Quote

interface eth0 {
        AdvSendAdvert on;
        MinRtrAdvInterval 3;
        prefix 2001:470:36:270::/64 {
                AdvOnLink on;
                AdvAutonomous on;
                AdvRouterAddr on;
        };
};

If your routable /64 isn't 2001:470:36:270, then you'll need to fix your radvd.conf and restart radvd.

If you're wondering where the rest of the stateless address comes from, it's the MAC address of the interface converted to EUI-64.

what did u mean, doesn't it need to put the prefix that i got from HE 2001:470:36:270/64??

There are TWO networks involved. One is the tunnel between you and Hurricane Electric.
Your configuration details seem to imply that the tunnel uses 2001:470:36:270::/64, which is what you're telling RADVD to advertise to your LAN. Since that's not your network, that's not going to work. That network is only used with the connection between your endpoint and the servers at HE.

In addition to the tunnel /64, HE provides you with a routed /64 or a routed /48. That is the network that RA should be advertising to your LAN. Basically, HE sets up routing for IPv6 to send any traffic to that network prefix towards your server, which then routes the traffic onto your internal LAN.
Title: Re: IPv6 stateless autoconfiguration
Post by: smith21 on October 21, 2011, 02:52:02 AM
this is my tunnel details:

Code: [Select]
Server IPv4 Address:216.218.221.42
Server IPv6 Address:2001:470:35:270::1/64
Client IPv4 Address:202.47.88.67
Client IPv6 Address:2001:470:35:270::2/6

Routed IPv6 Prefixes
Routed /64:2001:470:36:270::/64
Routed /48:2001:470:ec64::/48

The network which is only used with the connection between your endpoint and the servers at HE.
The conf are:
Code: [Select]
modprobe ipv6
ip tunnel add he-ipv6 mode sit remote 216.218.221.42 local 202.47.88.67 ttl 255
ip link set he-ipv6 up
ip addr add 2001:470:35:270::2/64 dev he-ipv6
ip route add ::/0 dev he-ipv6
ip -f inet6 addr

so,now i wanna make it as router that can connect multiple clients through wireless because as discussed here before that is also able to connect thru wireless (not only LAN) by using radvd.conf
radvd.conf:
Code: [Select]

interface eth0 {
        AdvSendAdvert on;
        MinRtrAdvInterval 3;
        prefix 2001:470:36:270::/64 {
                AdvOnLink on;
                AdvAutonomous on;
                AdvRouterAddr on;
        };
};


and the router and client are in different network, so as suggested by mr.cholzhauer i shud use prefix /48 for client interface:
Code: [Select]
auto wlan0
iface wlan0 inet6 static
        address 2001:470:ec64::2
        netmask 4

for the router:
Code: [Select]
auto eth0
iface eth0 inet6 static
        address 2001:470:36:270::1
        netmask 64

#radvdump

^C
*error

and the client still cant connect to ipv6 site
client ifconfig:
Code: [Select]

It looks like your hosts are getting an address...that's good.

First, I wouldn't bother using the 2001:470:36:270::/64 for anything...you have 64k worth of /64's in your /48, so I don't think you're going to run out

Second, you need to have a route for that /48 on your router. 
Title: Re: IPv6 stateless autoconfiguration
Post by: smith21 on October 21, 2011, 04:12:47 AM
so i also need to assign /48 besides /64 in the router? is it something look like this code?

Code: [Select]
auto eth0
iface eth0 inet6 static
        address 2001:470:36:270::1
        netmask 64
        address 2001:470:ec64::1
        netmask 48
Title: Re: IPv6 stateless autoconfiguration
Post by: cholzhauer on October 21, 2011, 04:26:23 AM
No...the only place your /48 goes is in your routing table.  Look at "netstat -nr" to see the current one
Title: Re: IPv6 stateless autoconfiguration
Post by: smith21 on October 23, 2011, 07:17:40 PM
this is my routing table:

Code: [Select]
[root@ip6 ~]# netstat -nr
Kernel IP routing table
Destination      Gateway                Genmask                Flags    MSS Window  irtt Iface
202.47.88.64    0.0.0.0                   255.255.255.240        U           0 0              0 eth0
172.27.11.0      0.0.0.0                   255.255.255.0            U           0 0              0 eth2
0.0.0.0              202.47.88.65         0.0.0.0                        UG         0 0              0 eth0

so, how i do create a route for that /48 on my routing table?

Title: Re: IPv6 stateless autoconfiguration
Post by: cholzhauer on October 24, 2011, 05:55:54 AM
I went and looked for a network diagram, but didn't see one

You just need to route it to the next hop...For example, I route my /48 from my tunnel server to my firewall (so my tunnel server knows where to send it)
Title: Re: IPv6 stateless autoconfiguration
