2501 routers-what do you think?

| Each transceiver is worth about 15.00 and the cable is worth about 5.00-10.00 (depending on length). That means that he's charging about 60.00 per router. That's not a bad deal at all. I'd maybe ask for a different IOS version though.
Looks like you'd be able to add more flash and more DRAM later if you wanted to because those routers have fairly recent boot roms installed. It appears that older bootstrap code didn't like flash chips from certain manufacturers. | |

| Wow, awesome rundown. Thanks, smrkdown. Which IOS version should I ask for? | |
| sandy7000 2004-09-03, 3:22 pm |
| I know, I know. I'll google it later. | |

The IOS is already loaded on the routers. The IOS version shown in your link is 12.0(27)GD IP/FW. I don't know that they'd load another IOS without upping the price (if they'd do it at all). The problem with upgrading IOS is usually more flash/DRAM required, which will increase the price. | |
| smrkdown 2004-09-03, 4:21 pm |
| Some people offer to load whichever IOS you choose (granted it will fit). I'd rather have IP Plus than IP/FW. I'm not sure if it would fit on 8 MB DRAM or not... You should be okay with FW for now. Should be able to do all things that CCNA requires. If you upgrade your flash and DRAM later, I'd definately recommend IOS version 12.2 with IP Plus, Enterprise Plus, or Service Provider feature sets. | |

| I think that'll keep me busy for a while.
Like you both noted, it's enough for the CCNA. Wish me luck...or at least limited frustration. 
P.S. stnosc, did you get that IOS info from Cisco or from another site? Either way, I'll google it. | |
| sandy7000 2004-09-03, 6:25 pm |
| P.S. Thanks, stnosc, for posting. | |

I have a CCO account at Cisco. A whole new world opens up to you with one of those...
Good luck in your pursuit of the CCNA. | |

| I got my routers 2501's from ebay too and I loaded IOS 12.2 and it fit just exactly.
I wasn't able to get a contract or support from cisco because I didn't purchase it from an authorized reseller *shrug*
Is there any other way you can get a CCO account? for example if I am a cisco academy student maybe? | |
|
| You get CCO accounts either by having a smartnet contract or if you are a CCIE (I know that does not help). Even then you can only download IOS if your smartnet contract allows it (for example I cannot download IOS using my CCIE account). | |
|
| on the config you have you can run IP plus 12.0 and and 12.1, to go to 12.2 you need 10meg ram and 12 meg flash even IP only. 12.2 is a mostly about QoS in terms of features and IP Plus is NAT, IBM bridging and maybe some other off the wall things so IP/FW should do you fine. | |
| sandy7000 2004-09-10, 6:46 pm |
| Thanks. I received the confirmation email....my babies are on their way.

| smrkdown 2004-09-10, 7:11 pm |
| 12.2 is the current IOS version used in the CCIE R&S track. It has alot of added features since version 12.0 above and beyond QOS.
12.3 is available as a limited development release for the 2500 platform and features IPv6 support which is and will be very useful.
12.0 will be okay for CCNA. If you plan to move beyond that, you'll want to look into upgrading. | |

| There is no certainty that IPv6 will ever make it into the public domain. The urgency for such a change has long been eliminated, so while eventually something will be done, don't be surprised if it is not just a variant of IPv6 or something totally different.

| I don't think that CIDR and NAT/PAT have in any way alleviated the shortage of public addresses. I also don't think that there will be much effort put forth to develop yet another standard different than IPv6 to perform the same function. IPv6 integrates well with the existing IPv4 environments. Support for it has already found its way into many routing architectures as well as desktop operating systems. It is also part of the curriculum for higher level Cisco exams. I would say that it is already in the public domain. | |

Maybe not, but the DoD has mandated IPv6 for their networks by 2008.
http://www.ipv6style.jp/en/news/2003/0616_dod.shtml
We are going to be migrating our internal network to IPv6 next fiscal year, and have already started testing it. | |

| While we are a bit off topic, IPv6 is very big in AsiaPac. If I was going again I would expect to see it as soon as they put it on the list of things they can throw at you.
By the by when I studied for the R&S lab I had several down release boxes. I found that having many boxes even if old, allowed to to keep a 'dirty' lab (several things going on at once) and debuging the unintended interactions helped me get all the points in troubleshooting. |
