On one side of the argument, folks saying that the need to manage two
configurations impairs IPv6's deployment.
On the other, an individual whose thesis was the IPv6 could not have
been designed to be backwards compatible
with IPv4 in a way that required no new configuration, just
incremental, backward-compatible software upgrades.
Why did you choose this route, instead of encapsulating the packet with
the extended address into an IPv4 packet ? I was out to prove a point. I needed a technique that, at least in theory, would start working as a result of software upgrades alone, needing no configuration changes or other operator intervention. If I couldn't do that, my debate opponent was right -- a greenfield approach to IPv6 made more sense despite the deployment challenge. Map-encap, where you select a decapsulator (consult the map) and then send a tunneled packet (encapsulated) does some cool stuff, but it's a pretty significant change to the network architecture. Definitely not configuration-free. Regards, Bill Herrin -- William Herrin bill () herrin us https://bill.herrin.us/
