NAT-PT isn't just NAT for IPv6. It actually does the complicated job of
translating from v4 to v6 and vice-versa. It's very memory and CPU
intensive, and requires a rather high-end router. It's primary purpose
is migration from v4 to v6. So you can roll out a network of just v6,
and still have a way to get to the 'old' Internet, via a NAT-PT gateway.
If they're scattered across enough time zones, you can serve many v6
users with a lot less v4 addresses.

Wow, and hear I thought the point of having a veritable boatload of
addresses in IPV6 was supposed to make NAT die. :) This is a moment of
irony.
Anyway, those commands showed up in 12.2(13)T releases. I have
12.2(15)T9
working on a 3620 and those commands are there. What router are you on?

Hi,
Can someone tell me an IOS image that supports IPv6 NAT-PT. I am using
12.2(15)T9 and this does not seem to have the 'ipv6 nat' command under
interface.
Also how likely is it that this topic will appear in the lab? I am a
little
unsure about this.
Thanks
Rohan
