Cisco newbie needs help - help configuring router.....

jabb000

I am new to Cisco and I am trying to learn.

I am wondering if someone could walk me thru the steps of getting a router configured properly.

I have a 2501 and 2513 Cisco Router that I am going to use for my initial lab. Then I will add on.

Could someone walk me thru the proper steps to get the 2501 configured correctly (see attached diagram ) then I will use that as a learn tool so I can configure the 2513? I would like help with configuring the solid line part of the network then I will do the dotted line for practice. Then later I will get a Switch and do it.

If there is a better set up then what I described please let me know as I am brand new to Cisco.

I would like the Telnet and SSH configured as well. For ease of remembering PW all pw's will be cisco for now.

Check out the CCNA TechNote: Basic Cisco Router Configuration and Management and see if that helps.

You learn these basic tasks as part of studying for the CCNA exam and they should be any good CCNA Study book (like the Odom Cisco Press CCNA Library or Todd Lammle's Sybex book).

SSH config is covered in a Cisco Technote -- Configuring Secure Shell on Routers and Switches Running Cisco IOS. Your IOS would have to be a crypto image -- one with k9 in the name.

Here is what I have come up with so far.

I can ping that IP perfectly but I can't Telnet in. I can't ping from the console port to the other computer.

*****RUNNING CONFIG*****

RouterA#show running-config
Building configuration...

Current configuration:
!
version 11.3
no service password-encryption
!
hostname RouterA
!

line aux 0
line vty 0 4

!
end

===================

I think something little just clicked. I know know and understand how to get to the interfaces to configure them. YES - it is coming to me........

I don't understand why it doesn't say no shutdown and default-gateway under ethernet0 when I executed these commands when I was in "interface ethernet0". == can anybody explain this to me please.

The aux port is not the ethernet interface, the one marked "AUI" is what you are looking for. You will need a transceiver to connect it to a 10baseT network.

A transceiver is one of these for example:
http://cgi.ebay.co.uk/Cisco-AUI-Ethernet-10Base-T-RJ45-Transceiver-D-Link_W0QQitemZ300175046093QQihZ020QQcategoryZ73321QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

It converts the AUI port to an RJ45 port. May as well get a couple of them I guess if you've got two devices.

jabb000

Thanks for your reply - I have a transceiver connected to the "AUI" port and an RJ45 cable going from the end of the transceiver to a port in the startecch switch.

SORRY for the confusion.

I can ping the 2501 router from the puter upstairs and from a wireless puter as I roam the house.

anything.............

The "ip deafult-gateway" command can only be used if you disable routing with the "no ip routing
command, you should change it to "ip route 0.0.0.0 0.0.0.0 192.168.2.1". You haven't made any changes to the config under line vty 0 4? that should ne the only rason you can't telnet (or you've created an acl somewhere)

jabb000

ok - cool - I will change that and change the typo in the banner........

jabb000

Yes - I have not made any changes to the VTY port yet. I will work on this now if I could figure it out.

Without knowing the IP address subnetting scheme you are using it is hard to determine what lse may be going wrong. Make sure ip routing is on and post some outputs of "sho ip interface brie" as well as "sho ip int eth0" and "sho ip route" that may help shed some light on it.

jabb000

I will use anything that gets the job done......... what is a good subnet to make this happen.

I was thinking about using the one in the techlabs......

I will post the show commands as soon as i eat.......thanks

Thanks buddy!

Based on the output of the show interface command, your ethernet 0 is up/down, what type of cable did you use to connect it and what is it connected to? If you are connecting it to a switch you need a straight through cable, if you are connecting it to your PC you need a crossover cable.

jabb000

The router is connected to "startech" switch with a cat5 patch cable......and I am using the console port to cinfigure the router

My network diagram is in my first post..........

dtlokee

Then you may have a bad Cat 5 cable or transceiver, the line is not up.

jabb000

Let em replace them and try it again..........

B-I-N-G-O - it was a bad cat5 cable.

now I have the "LINK" light on the transceiver is green....BUT now I can't get to the internet from the computer that the console cable is hooked to...it worked perfectly fine before.....


anything.......................

You can't pull services through the console cable... Do you have an ethernet connection to your switch or router? You REALLY need to start learning a little before jumping into this. A few chapters and you will have a better grasp of what you need to.

jabb000

Hi - I have read the ICND1 book and now I am trying to pu tit to use in a practical home lab. I learn better with hands on then reading a book.

I'm not trying to get to the internet via a console cable just merely stating that now the computer that has the console cable connected to it can't get to the internet. Hopefully this would help diagnose a probolem.

I diagnose that windows problem myself.

Looks like I have the ethernet0 port configured. Now I will move on to configure vty. Then connect the second router via the serial cable and then configure the two serial ports. Then I will add static routes.

Once I walk thru configuring the first router I will get it. Like I said as I was walking thru the first one it clicked to what I had to do to configure the ports, Now I just need to walk thru how to configure the vty then I will have that part.

I'm more of a practical lab hands on learner. Reading a book doesn't do it for me. I have to do it once or twice then I will have it.

Sorry and like always I really appreciate your help!!

Thanks!!

I can successfully ping the gateway and a comoputer on the network so I am going to so that it is set-up correctly.

Thanks guys! now I will concentrate on setting up the vty .

Thanks!!!

Telnet problem is solved. - it was USER ERROR......

SORRY guys!

Thanks.

Now next to configure is SSH....
