In the CCIE R&S Lab Blueprint, IPv6 is under IGP and BGP, does that mean it will cover RIPng (RIP for IPv6), OSPFv3 (OSPF for IPv6) and MP BGP for IPv6?
I have another question here for the hardware I can use for these IPv6 routing protocols. I have some 2610 and 2620 routers, and all of them have 64MB/16MB memory. For 2510 routers, I found the IOS image which supports RIPng and MP BGP for IPv6, but doesn't support OSPFv3 and IPv6 QoS. For 2620 routers, I found the IOS image which support RIPng, MP BGP for IPv6, OSPFv3, and IPv6 QoS. However, this iamge needs 64MB/32MB memory. So I can install this image on the 2620 routers.
Someone told me that there is a trick you can install (tftp) the image into DRAM (thus by pass the flash memory) and run the IOS from the DRAM on 2620. In addtion, you can even put 2600XM IOS image on 2620 router by using that trick. If that is true, then it will be great because 2600XM image can cover complete feature sets of 12.3 and 12.4 (Advanced Enterprise version), which can cover all IPv6 features such as IPv6 Multicast, IPv6 policy-base routing, IPv6 IS-IS. But I just don't know how to do that.
Certainly another way is to buy 2600XM routers, but that will be really too expensive for me.
Thanks you very much for the help.

I would suggest that you make yourself familiar with IPv6 QOS, NAT-PT and
tunneling. I am not saying these will necessarily be on the lab, but I am
sure they can come up.
Just because the blueprint does not have a section on IPv6 QOS or IPv6
NAT-PT explicitly does not mean a thing.
When you read the blueprint, I would treat it as a general topic. The
blueprint says QOS - not IPv4 QOS. The blueprint mentions GRE, mmm, that is
Generic Routing Encapsulation - which means you can use it for almost
anything (not just IPv4).
When there is an expectation of full reachability you need to know all your
options, this includes IPv4 and IPv6 - so NAT-PT, ISATAP, 6to4 I would say
are all fair game. So I would do yourselves a favour and at least
familiarise yourselves with these topics, find where they are on the DocCd
and configure them at least a few times in order to understand where the
pitfalls are.
Prior to my last attempt, I think I tried and covered every IPv6 scenario I
could make up from the command set / configuration guide on the DocCd. I
really think this put me in good stead for the IPv6 section of the lab. Not
even 5% of the IPv6 stuff I learned was covered in the lab, but it made that
little 5% heck of a lot easier.

Agreed. I had heard this same thing from one of the proctors...expect more
core technologies, not necessarily more IPv6.

In talking with the proctor before the lab, we inquired about the
changes
coming in January. He said to expect other features to be added (IOS
features in 12.3/4, etc.. to make up the lost points) and that they
wouldn't
necessarily beef up IPv6 past where it is today because they don't see
the demand for it.
