I read mostly the same things on Cisco's web site that you do! :) While it
is on the exam, it does not appear to be a "core" topic. So I think it's
safe to say that the entire IP stack will not be replaced with IPv6! I
certainly can't think of any good reason why Cisco would do that before
anyone else in the real world is doing that.

Hi Scott,
Thnx for your advice...Can you also clarfiy whether IPV6 will be a sub topic
in CCIE LAB JAN 2005 or The entire IP Addressing will be IPV6.
Thnx & Regards

Saying it's no different is a huge understatement. :)
Many rules change when it comes to how you program the routing protocols...
However, in the grand scheme of things, just realize that it is not a "core"
topic....
Learn the general concepts and know how to look things up on the DocCD...
The CD has very good information about dealing with IPv6.
788 pages is nice if you want to implement it. Skimming it, playing with it
once or twice and knowing where to look it up is nice if you want to not
freak out when it shows up on your CCIE lab exam in January!

IPv6 is not any different than IPv4 with exception of few proto related
cosmetic changes such as anycast, etc, etc. As far as inter-routing goes its
not any different in conceptual thoughts.
You do need to get some idea of how the subnetting and addressing types
work, which there is a good documentation here:
There are lots of IPv6 addresses to spare today and there are few tunnel
brokers / tunnel providers who can provide anyone with a tunnel and live BGP
session to setup IPv6. You will then need to know how to setup MP-BGP for
ipv6-unicast and do basic ipv6 static routing and stuff -- if you have
multiple routers, learn about v6 isis or ospfv3 as appropriate. One can
easily assign one of the cisco routers in your rack with a live public IP to
terminate the ipv6-in-ipv4 tunnel and get a /48 v6 delegation to lab it up
with thru the entire rack.
If you have strong conceptual knowledge in ipv4 routing (IGP, BGP), you
should not find problems quickly picking up IPv6 routing.
There are few tunnel brokers who also can throw in a BGP feed for enduser to
play with, such as hurrican electric tunnelbroker (www.tunnelbroker.net).
I myself also run a relatively large 6bone pTLA network providing free
experimental transit to several ASN's (some tunnels, some native), if anyone
is also interested.
