Like you say, anything is possible. But this takes away some of the fun in
making sure you have all routes, so in my opinion, this would be avoided.
Still good to know the basics and where to loook it up at, just in case!

Hi Chuck,
Based on your answer, can we realistically expect to see this on the lab?
(Yes, I know that on the lab anything goes).
Thanks
Rohan

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
