When I was prepping for the CCIE, a friend of mine used to always ****
with my lab configuration, attempting to jack things up in a manner
from which I could not recover. Once, he replaced the IOS of a 2500
router with a 4MB mpg file, and renamed the file to that of a valid
IOS image. I spent 30 minutes trying to get the "image" to boot.

What are some clever things that you've found you can do to sabotage
Cisco Networks? I am particularly interested in tricks that leave
either a small configuration footprint, or no footprint at all. Clever
protocol tricks are particularly amusing.

'no ip routing' will generally keep noobs busy for awhile.

I have my doubts you're a CCIE if you have to ask!!!!

Playing with the config register is always a good larf, as is dropping the
cam aging timers on switches.

1) routing loops as a result of summary and default routes are good.
2) Mismatched MTU size on serial links that break OSPF.
3) Mismatched IPSec crypto ACLs.
4) dialer maps w/o the key word "broadcast"
5) BGP timers that are shorter than IGP timers.
6) OSPF next-hops that are external types are fun to troubleshoot.

Of course, changing prompts, config-registers and the like are not
included as they are too easy.

Idiots!!

Just because someone has a CCIE doesn't mean they know everything
about everything! There's no harm in asking for advice and help from
others. I have no Cisco certification, just many years of network
experience. I often ask others for advice and on many occasions I have
asked CCIE's for answers to questions and they don't know the answer.

If you guys think that you don't need to ask others for help and
advice, then you are either the best network experts that have ever
walked the earth or idiots. I've already made my choice.

Who said "we don't need to ask others for help". The way the OP phrased the
question, it was obvious he wasn't who he said he was.

Yes - we agree - you are an Idiot! Especially if you can't tell a troll
pretending to be someone else.

Pete, you're a loser. In your own words, you've got no certifications
yourself, haven't attempted any, and IMHO haven't even got the slightest
understanding of what it takes to even get a CCNA! because if you had,
you'd realise what it takes to be a CCIE !

The biggest giveaway in 'Erich Trowbridge's' post was his line

"'no ip routing' will generally keep noobs busy for awhile. " ...

NO IP ROUTING !!!! is that the best a CCIE could come up with... ah come on,
pull the other one. You're so gullible it's unreal.

And I even question your silly claim "I often ask others for advice and on
many occasions I have asked CCIE's for answers to questions and they don't
know the answer"..

i'd like you to prove me wrong ? find me a post of your on google that
proves otherwise.. actually..forget it.. I know your answer allready, you
didn't ask anyone on usenet! how appropriate!!!

I see that "volotile" is a good handle to use.
Mr. Acid, you really need to simmer down with the name calling.
Yes, you're an 'eager beaver,' but please a little courtesy....

Whoa ho! Volatile Acid certainly is a good handle!!

I really really shouldn't get drawn into this, but here goes.....

I accept that I went over the top with the tone of my first post in
this thread. Sorry for that.

The first reply in the thread said "I have my doubts you're a CCIE if
you have to ask!!!!"

I wasn't questioning whether Erich really is a CCIE or not, and I
wasn't terribly interested . That wasn't the point of my post. That
reply says to me that "if you are a CCIE, you shouldn't need to ask",
but yes I suppose it could simply be that he was questioning whether
Erich was a CCIE - it was the "if you have to ask" part that prompted
my post.

I also wasn't knocking CCIE's. Anyone who has achieved the CCIE
qualification has my utmost admiration. I was just saying that just
because someone has a CCIE, it doesn't mean they know everything -
hence my point about asking others when you need to. I know exactly
what is entailed in getting your CCIE - I have two very good friends
who are both CCIE's. (Incidentally, I have also worked with both of
them and both say that I could get a CCNA with no problem at all - one
of them teaches CCNA too). I've been around a long time and am getting
somewhat long in the tooth (I've been in Data Comms and Networking
since 1976), and I have never needed to get the Cisco qualifications
to get work, so I simply haven't bothered. If I did need to, I would
work my way through the qualifications. I am reasonably confident that
I could get my CCIE.

Most of my questions that CCIE's have been unable to answer have been
when I have been working in the same place as the CCIE was (therefore
no need to post here), and most of those CCIEs were Cisco employees.
Ones that I can recall off the top of my head include questions that I
had when I was working on WLAN implementations related to APs, LEAP
(this was a while ago now), and Cisco ACS authentication with WinNT
domains and RSA SecurID ACE server. Other questions have included
things like BSTUN timers when I was working on a large network that
used BSTUN extensively. Some were complex questions and quite frankly
I would have been very surprised and impressed if the people I asked
had known the answers off the top of their heads, CCIEs or not. We did
get answers in most cases when they were referred to other people back
at the Cisco offices, who were presumably CCIEs too , or in some
cases the Cisco TAC (apart from one of the BSTUN questions which we
never got a definitive answer to - it was to do with changing the
keep-alive timers because they were activating ISDN lines to remote
sites if you really want to know - but I don't suppose you do!).

Oh - and I never got an answer to my post about "Default Netmask on
VPN Client" back in February.

If this being a loser, then yes, ok I agree.

Pete
