Hi ! &nbsp;I work for a company that wants the world for nothing - but then don't we all !!!!!!<br />
I have been asked to set up a test lab consisting of 3 &quot;sites&quot; with full mesh WAN connectivity at no cost (!). &nbsp;I have asked some people for some Cisco kit to build the design but the only kit I have been offered is a number of Cisco 4k routers. &nbsp;I have double-checked with the people in question and they confirm that they are very old Cisco 4k routers - and not Catalyst 4k's.<br />
My question is - is there anyone there in EE-land that has ever worked/configured these beasts ? &nbsp;What IOS version can I fit on them ???????? &nbsp;I had a look around the Cisco website and the oracle known as Google and I can't get any info of any use.........any help appreciated.

OLD Cisco routers - 4K

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
