Wanted FREE advice for Cisco 2500 Series routers for CCNA

www.techexams.net/forums/viewtopic.php?t=3349

8/16 will do just fine for CCNA, and although 12.x is preferable, you can do far out most of tasks with an 11.x.

You will need at least 2 routers.

There are many posts about home labs involving 2500 series in this forum, please try a search. Or check out this one:

there is a ebay seller i purchased 2 2501 with ver 12 ios for about 100 total.. however you will need to locate some dce to dte cables. you should also get a 1924 switch also. i'm in need of a switch but i'm thinking on buying one of the higher models to go into the ccnp track. they also have some great training dvd as well i like those with a book that way your can learn from dvd and pick up the book and have it make sense quicker (what book? todd's sybex of course)

Thanks.

I have to admit WAN seems like a 'strange land' to me. I am sure most of my current questions will be answered once I get the router and many more will unfold.

Several people left me with the impression that I wouldn't actually need a router and that I could get by with simulators. I don't see how I could ever prepare for the exam w/o at least one Cisco router.

I am going to buy a 2501 from a guy here in Dallas , who I met on Ebay. He is gonna include cables and transcievers and a bunch of cat5. (ya like I need more cat5 , lol) I'll pick it at noon today.

As you can read in the My Router Lab topic (link in my previous reply) and in several other posts regarding home labs, a simulator is good and better than nothing, but it certainly doesn't beat the real thing (cabling is an important and good example of what you won't gain experience with when using a sim).

However, as I mentioned in my previous reply, you will really need at least two cisco routers to build a CCNA lab. (a simulator is still better than only one router). You cannot build a WAN or actually use routing protocols with only one router (most of the CCNA exam is about these topics). You won't be able to even use the Serial interface with only one router (it won't get up because there is no link with a serial interface on another router).

Check out www.techexams.net/techlabs/ccna/lab_hardware.shtml for an overview of the most common (and minimal) CCNA lab setup including cables and connectors.

Good luck and have fun!

Along with the 2501, You should get a 4500 or 4700 router with 4 serial ports and 2 ethernet ports. This way you can do frame-relay.

I say (2) 2501 routers and (2) switches will be fine. I think a routersim will be fine too if you can't dish out the $$$ for the equipment.

But I do agree with the WebMaster...a routersim will not give you the chance to cable the equipment.

The router simulator does not give all of the available commands for debugging and show. They have coded just enough commands to let you learn key topics but not get intimately familiar with them.

Is the Cisco IOS upgradeable? I am asume it is.

any ios is upgradable if the router has enough flash onboard or you may have to purchase additional. i'm selling off 2 routers on ebay also

I tried to download an updated IOS from Cisco.com. I don't think I can do that with a guest account. Any sugestions?

You must have a CCO account to download IOS images from Cisco.

There is however, a program called "IOSHunter" that will aid in your search for an IOS.

This program does NOT look for images created after 2002.

if you want to setup frame relay - you must have at least 3 routers : 2 for clients and 1 for frs/frame relay switch... but if you want to study routing function only its ok to have 2. best if you have 1 switch also - you know - to learn that vlan thing.

You can do frame-relay with 2 routers as long as one of them has 3 serial ports.

You can set up frame-relay on two routers with a single serial back-to-back connection. It won't be typical example of a frame relay network, and you would never set it up like that in a real-life scenario, but for practicing some of the commands it can be useful. I think I wrote down the config for two 2501 routers, but that was about 6 years ago so I have to do some digging first. It may very well be on the cisco site as well.

Here's a link to Cisco's "Comprehensive Guide to Configuring and Troubleshooting Frame Relay":

This will help you immensely.

You can set up back to back frame-relay but you don't get the full benefits for debugging the LMI.

also you will or you should get a 2600 router b/c the 2500 don't support ISL.
