Thank you all Two questions: If I get the HE as upstream to advertsie our ipv6, 1/ Do we still have www.tunnelbroker.net as tunneling connection? 2/ All the internet users can access our ipv6 website? Thank you On Tue, Jun 28, 2011 at 2:09 PM, Kenny Sallee <kenny.sallee@gmail.com> wrote:
I did this by creating a 6to4 tunnel to a relay provided by
6in4, not 6to4. While HE do operate 6to4 relays, the brokered tunnel service is 6in4.
A very important distinction I didn't have clear in my head. To regurgitate some reading I just completed: both methods use v6 in v4 tunneling using ip proto 41 in the IPv4 protocol field. However, 6to4 derives the IPv4 tunnel destination of an IPv6 packet based on bits 17-48 of the IPv6 packet - which when converted, equals the 32 bit IPv4 destination. While 6in4 is statically configured IPv4 source and destination IP addresses on the Tunnel (gre) interface. In Cisco world the config comes down to 'tunnel mode ipv6ip' vs 'tunnel mode ipv6ip 6to4' and a few other lines of config. Of course there are a lot more details then that searchable via google. Thanks for pointing out my mistake - it helped me learn some more! Later, Kenny
