No pressure on you of course, but I'm 4/4 when predicting this - I think we
got another "first attempter" here!
Thanks,
Hobbs!

Subject: Re: which workbook are you using and why
i gotta focus on r&s until i've earned the right talk anymore :)
It is actually automatic on a frame-relay multipoint subinterface. The
interface goes down/down when all the remote dlci's go inactive. Here my
notes from a different lab but similar setup. i wasn't at home at the time
so i posted that query to gs...
R1, R3 and R5 connect via full mesh frame-relay, subnet 190.1.135.0/24. Only
R3 has the multipoint interface in this case. The others didn't matter
because I will be shutting those down.
R1 dlci 103 maps to R3 dlci 301
R1 dlci 105 maps to R5 dlci 501
R3 dlci 305 maps to R5 dlci 503
R3(config-if)#int s1/0.3 multipoint
R3(config-subif)# ip address 190.1.135.1 255.255.255.0
R3(config-subif)# frame-relay map ip 190.1.135.1 301 broadcast
R3(config-subif)# frame-relay map ip 190.1.135.5 305 broadcast
R3(config-subif)# no frame-relay inverse-arp
Bring up R5 and R1 again and now we have:
R3#show ip int brief s1/0.3
Interface IP-Address OK? Method Status Protocol
Serial1/0.3 190.1.135.1 YES manual up up
Shut down R5 and R3 is still up but look at the debug frame-relay lmi. The
status of PVC 305 is 0x0 which is inactive.
R3#show ip int brief s1/0.3
Interface IP-Address OK? Method Status Protocol
Serial1/0.3 190.1.135.1 YES manual up up
*Mar 1 08:27:43.170: Serial1/0(in): Status, myseq 115, pak size 45
*Mar 1 08:27:43.170: RT IE 1, length 1, type 0
*Mar 1 08:27:43.170: KA IE 3, length 2, yourseq 115, myseq 115
*Mar 1 08:27:43.170: PVC IE 0x7 , length 0x6 , dlci 301, status 0x2 , bw 0
*Mar 1 08:27:43.170: PVC IE 0x7 , length 0x6 , dlci 302, status 0x0 , bw 0
*Mar 1 08:27:43.170: PVC IE 0x7 , length 0x6 , dlci 304, status 0x2 , bw 0
*Mar 1 08:27:43.170: PVC IE 0x7 , length 0x6 , dlci 305, status 0x0 , bw 0
Now let's shut down R1 and take a look at R3 again, notice pvc 301 is now
status 0x0. and the interface is down/down on R3
*Mar 1 08:30:03.170: Serial1/0(in): Status, myseq 129, pak size 45
*Mar 1 08:30:03.170: RT IE 1, length 1, type 0
*Mar 1 08:30:03.170: KA IE 3, length 2, yourseq 129, myseq 129
*Mar 1 08:30:03.170: PVC IE 0x7 , length 0x6 , dlci 301, status 0x0 , bw 0
*Mar 1 08:30:03.170: PVC IE 0x7 , length 0x6 , dlci 302, status 0x0 , bw 0
*Mar 1 08:30:03.170: PVC IE 0x7 , length 0x6 , dlci 304, status 0x2 , bw 0
*Mar 1 08:30:03.174: PVC IE 0x7 , length 0x6 , dlci 305, status 0x0 , bw 0
R3#show ip int brief s1/0.3
Interface IP-Address OK? Method Status Protocol
Serial1/0.3 190.1.135.1 YES manual down down
What was driving me crazy was i couldn't get the above behavior to work (on
a different lab). I had removed the maps from subinterface for some reason
hoping to get it go down/down but that didnt work. anyways, hope that helps.
if i am missing something, please let me know

So now that we're past that (and we fight again when we are doing the
SP/VOICE track in race, right?)
What was the other way to get int s0/0.1 multipoint to go down without
dlci's?
I'm still learning too!

nope, no number yet. that's why I'm here. and i'll be trying as hard as I
can until I get it. and I won't take anything for granted. and I will always
consult multiple sources when in doubt. and i read the doccd everyday. my
favorite book is titled "Catalyst 3560 Switches, Rel. 12.2(44)SE, January
2008" and i have multiple vendor workbooks. and i lab EVERYTHING. and i take
notes and i review them. and when there's an unanswered post that piques my
curiosity, i'll try to find an answer. and when someone responds with a
incorrect answer or solution, i'll do my best to find the right one and post
it. and when there's something i just can't get a handle on, i'll search the
archives. and if I can't find it in the archives, i'll query the forum. and
if no on responds, i'll document it in a little notepad file called "things
i still need to research.txt". and i'll review those things every so often.
and i'll repeat the process until i am ready. and i may schedule my lab 6
months in advance, and i may not.
and when people like you try to crush the spirits of people you feel are
unworthy of the quest, i wonder what happened to you along the path that
made you that way

Nice one.
It will hurt a lot more once you actually pass the lab.
Or was your number on this last message in HTML #FFFFFF and I just missed
it?

Hey Joe, I seem to remember you telling me that EEK was the only way to get
multipoint interface to fail once the remote DLCI went down. Should I have
taken your word for it?
Don't worry, I'll make plenty of mistakes too and you can point them it.

That is probably the best answer or post on here in a long time Felix!
Very very well said!
Multiple workbooks! What's next? Removing the 30 day fail period,
You can just go to rtp for a week and take the lab five times?
;)

Hi Hobbs,
First of all, using a vendor workbook or attending a vendor bootcamp is not
a prerequisite to taking the lab or passing it. I know of some CCIEs who
passed their labs through self-study and practice, and not through the use
of any workbooks (Brian Dennis of IE is a typical example).
One thing you need to understand is that even though we call it a LAB, your
theory and understanding of networking concepts, technologies and their
interworking is tested much more than it appears on the outside.
You want to be a good network engineer when going for the lab (to pass it
and also for your career). Most candidates go for the lab with 'holes' in
their networking knowledge. Thanks the labs are good at exposing these
holes.
You could use a million workbooks from a million vendors, and if you still
dont seal the holes in your networking knowledge, you would still not pass.
Granted, vendor workbooks are supposed to help you do so. If you come to
think of it, how many different ways could one be tested on frame relay?
It's finite.
So if you settle on a workbook from a vendor who teaches the technologies
well and passes you through all the numerous scenarious of FR setups and
configurations (in about 10+ labs) so that you fully master the concepts, do
you think you've got to need a billion more workbooks before you can pass?
As experiences show, the key to passing the lab is mastering the concepts
and gaining the hands-on exposure. Any SINGLE good vendor could help you
achieve that.
Buy time to study and practice, rather than buying thousands of workbooks
and doing little study. And don't think Reading is the same as Studying. Go
figure!

Felix Nkansah, CCIE
