Thx for your replies! Wow! I see, there are tons of vendors! But when they support IPv6 or 6to4 IP6 Tunnel and so on... does they support the 6rd concept?
6to4 and 6rd are not the same and are not compatible. 6to4 has a given prefix while 6rd uses a prefix from the ISP to circumvent the case that a IPv6 packet which should be received by a 6to4 host never traverse a 6to4- gateway and so will never enter the IPv4 net.
In this case the packet will never reach the 6to4 host. There is no way to guarantee that a 6to4 gateway will ever traversed so this indeed a big weakness of 6to4.
