Hi Joe,
You're in SJ already?! If you're imminently sitting the lab, BEST OF
LUCK TO YOU!!!
As for frame, you bet! Dynamips/Dynagen has an integrated Ethernet
switch (nothing fancy but it's useful) and an integrated FR switch.
Regards,
Scott

I was in at SJ yesterday, getting warmed up in the atmosphere...
humidity is
about 20% a big break from RTP! That's for sure!
Found "building C" and checked it out... No promises, but I might
"Buster
Douglas" this thing yet!
Regarding dynagen, can you emulate a frame-relay network? I may join
the
dynagen side when I get my new 2GB ram laptop.

Joe,
I know you're busy preparing for your upcoming lab, so you've
probably
been ignoring my "blog" over on the board. With much help from the
Brians, I have a Dynamips-based router server up and running with
four
physical 3560 switches. So I can indeed have two "routers" talking
over
a multi-hop dot1q trunk chain.
I suppose you have a point on the interface problem thing. I don't
wish
that on anybody during their lab. Sure, it's an everyday thing that
you
might have to deal with in real life, but I think the lab has enough
built-in stress w/out that kind of nonsense!
Regards,
Scott

Things that can go wrong with the real gear, and only with the real
gear...
Will burn your time bad in the real lab to try and fix (loops, bad
interfaces, two routers talking together through 3 switches over a
dot1q-tunnel, etc)
I'm not saying you can't learn the technologies on the dynagen, but
I'm
saying spend some practices sessions on a full 10 piece rack.
That's all
Happy Dynagening...
-Joe

I am a true Dynamips/Dynagen believer and have built my lab prep
"rack"
around it/them. Please explain, Joe, how I will fail the CCIE lab
because of it ("nothing else can prepare you for the real thing")?
What
is it about that "feel" that makes the difference (can you go "feel"
the
routers during the practical? Can you "feel" the routers in that
remote
rack?)?
This has the potential to become the next "CCIE vs. college degree"
topic, me thinks. It's probably not a very good use of bandwidth,
come
to think of it LOL, but I can't resist asking you to elaborate on
these
seemingly unfounded generalizations. I would prefer that you answer
with
"I have hardware routers and I also run Dynamips/Dynagen on a machine
of
sufficient horsepower, and here are the things I can do on the former
that I can't do on the latter *that matter in the lab* (i.e. don't
tell
me about toggling the power switch...yawn...you can't do that in the
lab
anyway by all accounts I've ever heard).
I'll start, going the opposite direction:
I run Dynamips/Dynagen on a machine of sufficient horsepower, and I
can
directly capture traffic from a router interface into a .cap file and
scrutinize every one and zero using open source WireShark. When I
want
to do that w/ physical routers, I have to use Ethernet (no serial)
and
set up a span port on a switch or put a hub in between the two
routers,
with a machine running WireShark hanging off of the hub (and I'm
obviously in HDX at this point, which means the test environment is
different than the non-test environment). Otherwise, I'm limited to
only
debug. I, of course, acknowledge that you're limited to only debug in
the lab, but in your preparation for the lab, it's powerful to have
such
a tool at your disposal so that you can truly understand what's going
on
under the hood when you see certain debug output.
BTW, I'm told Juniper has this capability to write .cap files on
physical
routers, but I cannot personall y verify. I have never heard of such
a
capability on Cisco routers, but I'd love to be proven wrong.
There are more, of course, but I've already stated many of them in
other
recent threads and posts...

Nothing feels as good as the real thing. And else nothing can prepare
you
for the real thing.
(Remember if you only have had sex with a condom, your still a
virgin, LOL)
Check out the Brian's racks!
