kernel hangs after setting up Ipv6-ipv6 tunnel

Hi All,

Does anybody have any experience with setting up a IPv6-in-ipv6 tunnel
in linux?

My situation is like this:

I have a tunnel from my homenetwork to a our ipv6 test-network using an
apple airport express.
As that device does not support IPv6 multicast, I want to set up a
IPv6-over-IPv6 tunnel from my linux-box to the Ipv6-router and tunnel
IPv6 multicast traffic over it.

I followed the steps found here (sse linkg below), with the difference
that I set up a tunnel between a linux-box and a cisco-router, and not
between two linux boxes.
(URL:
http://linux-hacks.blogspot.com/2008/02/howto-ipv6-ipv6-tunnel-and-ip...)

On the cisco-side, I set up a standard ipv6-over-ipv6 tunnel, with PIM
configured on it.

On the linux-side, it works OK up to the point where I create the
tunnel, and then do a "ifconfig mytunnel multicast up".
Then the box hangs. :-(

Does anybody have simular experience, and -more interesting to me- also
have a solution?

On the linux-side, I run the ubuntu 8.04.1 with the latest kernel
(2.6.24-19-generic).

Cheerio! Kr. Bonne.

 
 
 

1. ipv6 tunneling in kernel 2.4.0-test8

Hello,
I use a tunnel of ipv6 (www.ipv6.ircd.it).
When I run this script in kernel 2.2.17, it work...
-------------------------------------------------
## script for tunnel-ipv6 ##
ifconfig sit0 up
ifconfig ippp0 add 3ffe:1001:200:b::8d/127
ifconfig sit0 tunnel ::194.247.166.147
ifconfig sit1 up
route -A inet6 add 2000::/3 gw fe80::194.247.166.147 dev sit1
-------------------------------------------------
but in kernel 2.4.0-test8 don't work, infact it give me this error:

SIOCSIFDSTADDR: No buffer space available
SIOCADDRT: Invalid argument
