Hi Robert,
In the lab I would use a tunnel when you need to run a protocol and/or pass
traffic (IPX, IGRP, etc.) between two routers but are not allowed to route
the traffic over every link between the routers.
I am planning to use IPSec any time there is a requirement for two routers
to use encryption, authentication or anti-replay technology. I don't plan to
use CET unless specifically asked to do so (which I doubt will be the case).
I'd be surprised if the lab will ask us to "configure a VPN..." simply
because - as many people have stated - everyone has a different idea of what
a VPN is. I think they may say "Configure R1 and R2 to pass encrypted
traffic between each other," etc.
I'm not sure I fully understand the requirements of #4. You can create a
tunnel, then run IPSec through it, though its more complicated that a tunnel
or IPSec alone.
Rob.

Subject: VPN
I have a couple of questions regarding VPN. All these questions are geared
towards the CCIE Lab, not the real world.
1.) In a lab scenario, when would I use IPSec?
2.) In a lab scenario, when would I use CET?
3.) In a lab scenario, when would I use a tunnel interface?
4.) I cam across the scenario: Configure a VPN between R7 and R6, a few
clients on R7 have a default gateway of 192.168.80.1, provide these users
with access to the 192.2.0.0
I am taking I need to configure some type of encryption, a tunnel interface
with a address of 192.168.80.1 going to the router that has the 192.2.0.0
address? Am I close on this?
Thank you,
