Problem with Lab 11.1

[sukarabi]

Hello, before all just a little mistake saw on number 2 of this Lab:
the "router rip" command is missing but everybody had already noticed that...
My problem is that I cannot ping from router ISP to Lab_C for example. I'm wondering how we could do that if Rip is not active on ISP. When I do "sh ip route" without routing protocol then I cannot see this network.

Ah there's one command who doesn't work on my 2500 simulated router. It's ip default-network, is it because of that ?

Otherwise, for sure I had troubleshoot my network lab before (clocking etc).
Thanks for any help.

After checking again my config and trying to remember my routing course, I finally change the cde "ip default-network xxxx" by "ip route 0.0.0.0 0.0.0.0 xxx" to setup a default internet gateway from Lab_A to ISP.
But it didn't resolved my prob of pinging.
When I try from Lab_C to ISP I cannot either but I can see ISP network in my routing table...

But I can ping from A to C or C to A. Seems to be a trouble for passing between A and ISP
zzzzzzzzzzz
After a good night sleeping I checked again. Now I understand that no need to start RIP on ISP because of "ip route 0.0.0.0 0.0.0.0 s0". But it doesn't solve my problem.

[lammle]

yes, the router rip command somehow is missing from the Lab_A config
however, with that said, the network should work with the rest of the configuration in the book.

Go through each router and verify your network statements under rip.
Also, verify that you don't have a typo with each interface ip address and make sure you can ping from router to router.

Cheers!

Hello sukarabi

I,ve the same pproblem whit the lab. I thinked about it and I think you can't ping and neither can telnet before make the NAT translation in Lab_A router. I think it becouse you put de serial 0/2 interface of Lab_A (connected to the ISP)in passive mode and you aren't running the RIP protocolo in the ISP, then the ISP dont know wny route to the Lab_C IP and cant give the answer o the echo from the Lab_C, if you have seen the route table at the ISP, there aren't any route to the 192.168.X.X network. But, after you make the NAT translation it works very good.
I belive the problem is the ping and telnet must not be before the NAT translation.
¿Am I good, Mr Lammble? Realy, I'm not sure

Yeah, I'm actually running into this same problem.

The issue, I think, has to do with being unable to use the ip default-network 171.16.10.1 command on the Lab_A router in the Boson NetSim.

I've been enjoying the book so far, and I've been working every lab and this is the first one I've run into a problem with.

I'll forge ahead and see if it works after the NAT setup, I guess.

I had the same issue but i figured this was not a "cookie cutter" lab and that we were supposed to figure out some of the stuff on our own. I noticed that the ip defualt-network command did not work at all for me so i just created a static route and then redistributed it with RIPv2. After that, everything worked great. I used packet tracer for all my labs. Seems to work our better because then my wifi conection on me laptop does not interfere with anything...

I take my ccna tomorrow>>>

The ip default-network command must be used against a route already in the routing table, to signify that any traffic for unkown routes should be passed to this network. It should then be distributed via routing protocols.

right, i had the 171.16.0.0 network in my routing table and it still wouldnt work. I even tried the lab out of my cisco netacad online program and still no go. I think it is just a fluke in packet tracer.

I took the CCNA today and scored 804 out of 825. I am trying a third time in two weeks.

I had some of the most ridiculous questions asked. It drove me nuts.

one question i had no idea because the scenario was never covered in any of my cisco books or in lammle's book so i had to guess. I didnt know what to do. it pissed me off.

[sukarabi]

Sorry for your ccna.
Please tell us what was your method of learning and preparing the test.
It would be usefull for everyone and we can may be give you advises based on our experience. Thanks and good luck for your preparation.

I took 10 months worth of classes from a CCIE. Its not his fault i did not pass. He is an amazing instructor. Its just ciscos way of earning money to put those kind of questions in the test.

I read most of lamles book but as i stated earlier, his book and the cisco press book did not have any scenarios like the ACL problem i encountered. Maybe i just got a dang hard problem. I can do all of lamless and cisco press labs with no problem by memory.

Here are the things i did to prepare. Besides school at my college, i did all the labs in lamles book and my cisco netacad books. I used packet tracer a ton because in there my laptops interface cards and wireless conention dont cause issues.

Here is my break down:

100% security
100% wireless
84% routing and troubleshooting
83% IP addressing
50% ACL's and NAT ( i know i configured nat right because the sim stated that if the host can ping the isp then i have completed it succesfully. Well it pinged)
66% VLANS
25% WANS
71% how does a network work.

804 out 825. 80% so not to bad.

other than that i guess be on the big guy in the skies good side.

To me it looks like your grasp of layer 3 topics is solid, you just need to work a little more on your layer 2 stuff. The ACL was maybe a curve ball question, but how did you find the WAN questions? Even if they asked only 4 questions on WANs, I can't see 3 of them not being mentioned in Todd's/CP books.

It's unfortunate but at least now you know the areas you need more review at. Go over them again and use as many resources as you can, Cisco's website has some great information, as does Wikipedia and the like.

[lammle]

I agree that Cisco did "step-up" the understanding of access lists in their objectives, so read my book, cisco's book and go get some time on routers. A lot of time!

All the WAN objectives, NAT objectives, Switching, etc, is covered 100% in my book, but you have to both read and do the labs.
Cheers!

I have read your book. Mr bridwell and Mr hutchings got me a copy of your book. Oh by the way they both told me to tell you hi and what not. They kinda miss ya lolol..

Any way i have read your book and done most if not all the labs. I use live and packet tracer for equipment.

Here is one question that threw me off.

They asked me what MAC address will the s0/0 with frame relay use as its source MAC.

A)888
B)775
C)341
D)457

I did show int s0/0 and it said hardware address was HD3775

I did a show frame relay ? and i think it was lmi u used to find the DLCI and it said 888 so i picked A.

I thought frame relay used DLCI's not MAC??

[lammle]

Frame Relay layer 2 addresses are called Data Link Connection Identifier (DLCI), not MAC addresses, those are only used on Wireless and Ethernet networks.

This is covered in my chapter 14.

You can see the DLCI that is used to get to a remote site with the show frame-relay map command.

i knew it. thats what i thought. So why did they ask me what MAC... I wrote that one down on my white board during testing so i would remember it when i left. See that bugs me they would ask that.

I am reading 14 as we speak. along with cisco press book WAN technologies.

thanx Mr lammle. I appreciate.

[lammle]

They didnt' ask you the MAC, they asked you the "layer 2 address in the heading", that's different, you just assumed MAC address.

[LT72884]

no they said MAC, i know the diff between layer 2 addresses. The wording said MAC. Thats why i was confused and why i wrote it down on my whiteboard during the test. The layer two would be the dlci but i got that one right anyway because of the show frame-relay map command.

any way next time im gonna pass the exam.

LOL i have decided i am crazy and insane. i Have been reading all day and my eyes are bleeding......
