Re: CCIE S/P Question

Like Antonio said, make sure you mix up the different IOS versions.

Quite some features aren't available or different in 12.2T compared to
12.3T. The routers in the lab can use these versions and you can run
into situations that you are certain of using a specific feature that
is suddenly not available :-)

Using 7500's is possible. I don't think there is anything that the
7200 supports that the 7500 doesn't. As long as you run 12.2S of
course. Try to stay of some specific (hardware related) features on
the 7500 platform.

It's true that some online rack rentals are not using 7200s. Like our
SP racks, we do offer an ATM rack which consists of 8! 7200 routers.
The more advanced labs in our workbooks uses this topology and will
test you on what you need to know about 12.2S features.

Again the SP lab uses 3 different IOS versions where you really need
to be aware of which router runs which version as the differences are
quite numerous and important!
