Because Dynamips uses the MIPS CPU emulator to build a hardware emulation of the Cisco hard are. The Cisco ISR routers don’t use MIPS CPU they use Intel i960 and NP’s (I think) which do not have a software emulation that is available in open source.

And why exactly wouldn’t it be “possible” to emulate an ISR?

I use Dynamips and GNS3 extensively, and I feel that the day that it becomes unusable as a viable training/”proof of concept” tool is quite a way off, but is also inevitable unless something is done about it. We need to be putting pressure on the Vendors to release (in some form) what they probably already have internally anyway.

Working for a VAR, I could virtually guarantee increased sales to any network vendor in the enterprise LAN market who supplied official emulation software for their router and switch products. The VAR engineers would be better trained and equipped, the client would be in a better position to develop and expand their new network, and ultimately the vendor would benefit.

Maybe once one major vendor does it, the others will follow suit.

It has always been a useful tool in the kit bag not only for the learning and training but also mimicing problems when troubleshooting.

While I doubt it will have any immediate effect as students will end up returning to buying and kitting out their own personal labs it will see a return of a less flexible learning environment.

Routing protocols won’t change much… I’d say most of the CCNA and CCNP is safe for a long while. Cisco isn’t out to revamp the whole IOS.

Features will be added and some will change. As IPv6 becomes more prevalent and changes are induced, perhaps then we’ll see Dynamips be broken for exam purposes. How many of us really had an ISDN switch when that was still on the exams?

Didn’t know about Zeus, but Netscaler is available too – it’s interesting that three major load balancing companies have gone down this route. You’d need to be pretty sure that ACE was going to do the trick for you when you can evaluate the competition..

Man, that’s a shame – I definitely agree with you as I’m currently using these tools on a laptop for my CCNA study, it would *so* be in Cisco’s interest to release an IOS VM for people to work with, EMC seem to have loads of success with the Celerra VSA, even just as a pre-sales/PoC sort of tool.

Zeus have done a similar thing with their product, free eval download – engage geeks get them to play/learn and it translates to sales later on.

It can’t be /that/ hard can it? – I had hoped the NX1000V was the start of this sort of software/VM version of tin thing, but nothing yet AFAIK
