My router lab

pandimus

Cool, that did it.. Thank ya...

Webmaster

You're welcome.

Must be hard studying for two non-Cisco exams with all the cool equipment nearby. Everything OK with the 2507? What IOS does it have?

Dont remind me johan. Have my study notes in my lap with a 2507 busted open lookin at the internals.. Bahh... Anyway's looks good sofar. I need to figure out the hub part. I think i need to enable a port or somethign attempting to get some activity from it to the switch.. Anyway, I will have all weekend once i get these 2 tests done. Good thing they are somewhat related.

Here is a printout of the show ver

I will have to upgrade the ram and the ios later, but as of now it's lookin good.

I didnt realize it, but the auction also came with/a console cable and 2 patch cables..

So now i have everything i need. I picked up 2 cisco brand transcievers, and the 2514 came with one transciever.

This router was the only thing i was waiting for.

So this weekend Minus the family get together, i'm gonna have a blast..

Webmaster

I assume you need to configure the Ethernet interface as usual (ip address .. .., no shutdown), and you may need to configure an individual hub port in hub configuration mode. Although I would expect it to work 'by default' once the eth 0 interface 'behind' the hub is configured with an IP address. The memory currently in it is sufficient I think.

Good luck with the exams. I guess becoming MCSE Security is 'somewhat' more important, but I can imagine you're looking forward to the weekend. Don't forget to party though.

Did you pick up a book yet? It's best to practice with some 'real-world' scenarios, which are also at www.cisco.com
I'll see if I can spend some time on writing more TechLabs, and/or create a list with good lab examples from the cisco site.

pandimus

Did you pick up a book yet?

Yup, the double series by wendell odom. I noticed the first one talks tons about subnetting and some network+ stuff. So hopefully just a quick brushup and i can start on the second one.

Good luck with the exams. I guess becoming MCSE Security is 'somewhat' more important, but I can imagine you're looking forward to the weekend. Don't forget to party though.

Yeah, i am a bit concerned about my exams.. We will see how they go. But yes, very excited to get away from MS for ahwhile. I am soo sick of their looong drug out questions. I hate the fact that every question starts with "your the network administrator for ......"

I'll see if I can spend some time on writing more TechLabs, and/or create a list with good lab examples from the cisco site.

I think these will be pretty important for the test.

Oh yeah, the book i bought comes with cisco lab software.. I havent installed it yet, but when i do i will tell all how much i like.

pandimus

I found that anthonypanda offers a buy it now on ebay for ram for 2 bux cheaper than on his web site.. Unfort he is located in HK, so your shipping options are limited.

Webmaster

I bought a V.35 DCE cable from them a while ago, and found that even with the shipping costs inlcuded, they were still cheap. In my case it would be $3 minimum for the RAM.

I hate the fact that every question starts with "your the network administrator for ......"

That does get old very fast. But Cisco will be a welcome change, the questions are shorter, straightforward (never really tricky, although sometimes the answers are long sentences with just a very minor detail making the difference), never ambigious (although one could say that about the sims), based on technical facts rather than opinions (although there is 'the Cisco-way' in some cases). Best of all is that the definit answer is always available in Cisco Press material and the Cisco site.

And compared with CompTIA... well, let's say Cisco is competent.

pandimus

I decided to attempt your techlab today.

Just a question.. When i hook up that DCE DTE cable.. Shouldnt i see a light on the serial port? Also i noticed on your configuring a rip network you have the dte dce hooked up to S2/S0

But on the hardware pic they are hooked up to the same serial port..

Webmaster

When they are up (as in no shutdown), they should flicker once in a while, both routers, indepent of eachother. Once you run the clockrate command on the DCE side, they should blink simultaneously. (when show int s0 shows line protocol is up.)

Also i noticed on your configuring a rip network you have the dte dce hooked up to S2/S0 But on the hardware pic they are hooked up to the same serial port..

Hmmm, I see what you mean, the diagram in both the Rip Lab and the Hardware Lab show S2. I'll change that to s0, although you can use any serial interface you like... except s2 cause there are only 2 serial interfaces...

pandimus

hmm

oh yeah

Change the update timer to 45 seconds, the invalid timer and the holddown timer to 270, and the flush timer to 360 seconds, using the following command:
Router(config-router)#timers-basic 45 270 270 360

This gives me an error unless i take out the hyphen

Webmaster

Thanks again. I thought I removed that one a while back after someone correctly commented the timers basic command is not part of the CCNA exam anyway. I removed the task entirely.

RouterB>show in ser0

I assume you already checked the cable connections... it may be the cable... try setting up a connection between other serial ports, to check if it is the cable or the interface.

pandimus

Interesting..

Changed to serial 1 and seems i get lights now after i set-up ip address.. But says state was up for a minute then went down..

OH yeah, how would i clear an interface ip address?

by using the 'no' version of the ip address command. This goes for any setting (i.e. no shutdown, no login, no password enable, etc.etc.).

Please paste the serial interfaces config from both routers.

Did you configure the clockrate on the DCE?

pandimus

not sure if this is what you want..

i did a show running-config

I did not completely set up ser 1 like the tech said, i was hoping to get it working..
!

Webmaster

On a serial connection, one of the routers needs to be configured as the DCE (automatically making the other the DTE). You can do this by using the clockrate command in interface config mode:
router2(config)#int s1
router2(config-if)#clockrate 64000
CTRL-Z
copy run start

Only one side of the connection will accept the command depending on the cable.

This issue has always been part of the CCNA exam... it's like the frametype thing in IPX neworks... if the serial line protocol is not up, this is the first thing to check.

Webmaster

Note that both your routers' s1 interfaces use the same IP address.

pandimus

Note that both your routers' s1 interfaces use the same IP address.

Note: Retard behind the keyboard.

I think we may have resolved the problem..

Let me monitor and see how she works..

Would be a pity if one of my serial int dont work, cause i will want to use this lab and more routers for CCNP

Webmaster

Well , I was thinking it should not put limitations on your lab. Say you would buy a third router, with at least 1 serial interface. You could still create the lab, ie.:

hosts--switch-eth0[router1]s1

---

s0[router2]s1

---

s0[router3]eth0--hosts

both router1 and router3 use only one serial int. Plus you got the extra ethernet interface on one of the routers for an extra network, and the switch to create VLANs. That should allow you to practice everything needed for the CCNP routing exam. And you'll never actually use all the serial interfaces.

pandimus

Sweeeeettt.. Configured my First RIP network.. Thanks for the TS tips johan..

Now what?? Go take my CCNA test???

Now to get VNC to work over This rip network. hehe..

pandimus

Yeah, your correct.. didnt think it through..

Maybe i should study SEC+... naaaaaaa.... This is too much fun..

Webmaster

You're welcome, I'm glad it worked out.

I assume you'll do fine on the Sec+ exam, but if you think you need some motivation: think about all the cool Cisco equipment you can buy from the cost of retaking the Sec+ exam.

pandimus

Guess i spoke too soon..

I thought i had her working as i was pinging from router A, but then realized i was pinging from router A..

Tried to ping from host one.. nada.. Tried telnet into router B nada..

Gateway on that nic is setup for router A's interface.

pandimus

Oh yeah, this computer is multihomed too. one leads to my dsl router as a means of providing me internet connection..

2lazybutsmart

well I managed to turn on my router at last. and this is the gibberish I got out of it

Webmaster

is the router in good health ?

Seems to be good so far. You can connect a computer to the router's ethernet interfaces using a crossover UTP cable, to check if the interfaces are ok.

2lazybutsmart

well I just got it connected to my hub. I checked both links and they're giving me a green light. I guess everything's OK.

I'm going to connect everything to my 3com Office connect hub (but don't I need a switch hub??). That'll be 3 computers in total on the network. I guess that should be fine for a lab right? But then I would need a second router to configure things like RIP networks and stuff right, or can I just forget that for now? (Dear me, getting a lab together isn't as easy as I thought anymore)

2lbs.

pandimus

just a note about my problem, i decided to try a ping from the opposite computer.. and it works all the way through.. Seems the problem is only with my computer through..

pandimus

I'm thinking its a gateway problem on my multi-homed comp. Cause for a minutes i was able to ping across, but at that moment i couldnt get acess to internet.. Think if i put each nic on different subnets that will fix the problem?
