Re: Interested in input on tunnels as an IPv6 transition technology

would be interested to know what people think
is good about tunnels as an IPv6 transition technology, and what people
think is bad about tunnels.
The good thing about tunnels is people can build them where there's no
proper network

The bad thing about tunnels is people build them instead of a
proper network

We've used an HE tunnel with BGP for about a year and it has not been
reliable enough for my tastes. However, I think it's great for testing -
I just wouldn't want to rely on it for production. One, it's not ideal
to force traffic over a tunnel that incurs additional processing,
latency, and reliability problems. Second, in the case of a free HE
tunnel, it might be viewed as impolite to send the tunnel provider lots
of data (I don't remember seeing a bandwidth usage policy).

Only in the case where local peers refuse to provide reliable IP6
transit would I consider using a tunnel full time for IP6 traffic. And
even then, probably only if I was paying and had some sort of service
guarantees and support from the tunnel provider. I would look at
switching local peers for transit before relying on a tunnel.
