Subject: My Number! #12508
I wanted to send a quick note. Got the magic number in San Jose, CA
last Thursday on my 4th attempt. Overall a great experience although I
started to get seriously burned out. I guess that's when you know
you're ready :) My first attempt was on token-ring/IPX/etc.. So it's
been a while in the works.
Thanks to everyone! I'll elaborate :)
Groupstudy has been very helpful. I found that trying to help people,
althought I didn't do it as much as I'd like to have, really helped me
learn in return. Many times I knew 80% of the answer someone was
looking for, which forced me to do a little research before I responded.
Brian's McGahan and Dennis, you guys are great. I can't think of a
better compliment to have than when a CCIE hopeful like myself starts
using your names instead of technologies in the search engine :)
CyscoExperts. You guys were very motivating for me. Being able to get
away from work for a week, plus having folks around that are so
motivating that you actually want to come in every day and lab for 12
hours is amazing. Your class is addictive and I found myself wanting to
stay another week and being willing to pay for it, just couldn't swing
the time off.
Doyle, Caslow, etc.. Good books. When you read the standard reading
list and everything makes absolute sense, you're doing good. If it
doesn't... Don't blow it off. Read other material and mess with stuff
until you get it.
Gordon Hughes for his wonderful motivation throughout. Same for Jim
Phillipo. Having a few buds that "feel your pain" meant the world to
me.
My wonderful girlfriend Melissa for being ultimately motivating and
understanding. Whether it was me being a troll in the study cave (and a
mean one when I was frustrated), or me playing Warcraft when I should've
been studying but was burnt, you dealt with it all like it was no
problem.
NetMasters DoIT and IPExperts gave me a lot of great labbing material.
I really appreciated the "Spot the Issues" section of DoIT labs. It's
nice to have an explanation of what's going on.
Take care and good luck. I'll be lurking on the list and will respond
if someone doesn't beat me to it.

Subject: RE: Ping scripts for routers.
Sorry about the long post, but a couple of people have emailed me
offlist for an example of what a TCL ping script looks like in action.
Again, the script itself is simple. Once you have it in Notepad, Ctrl+A
will select the script, Ctrl+C will copy the script, and from there you
can paste it into the terminal emulator (SecureCRT at RTP).
Here's one such script I ran not too long ago on a rental rack:
tclsh
foreach i {
172.16.105.1
[output omitted]
172.16.110.1
172.16.46.20
172.16.1.20
172.16.2.20
172.16.120.1
} {ping $i}
BTW, use this command to get out of the TCL prompt:
tclquit
-----
Below is an example copied from a SecureCRT window. All I did was paste
in the TCL script. The successful pings go by very quickly, but you have
to wait 5 seconds (5 pings) for every one that fails. This list has
about 30 routes and when all targets respond to the icmp echo, the whole
thing takes about 10 seconds to complete on that router. What I do is
open another Notepad and paste in the IP addresses of the few pings that
fail. Then I start looking for the cause of the failure.
Once again, this will NOT work on a Catalyst 3550, only a router (not a
2500 series, though).
You may want to remove ISDN interfaces from list, since you generally
won't have ISDN up all the time. The other thing you need to do is map
each router's own interface in ATM and Frame-Relay, that way you won't
be getting a timeout when you try to ping yourself on a given router. On
at least one occasion I've asked the proctor whether it's okay to map a
router's own interface and he basically said that in general, unless
it's prohibited or breaks something else, over-configuring is not marked
against you.
Maybe so, but it never hurts to ask about anything you are planing to
add to your configurations that is not specified in the lab booklet.
-Jonathan
Below is what happens when I paste the script into a router. From the
time I pasted it in until completion was less than 10 seconds.
