Is this how cisco is going to tackle dynamips??

I wonder why they are not supporting these anymore....

12.4(15)T is the last to be supported for these models:

So what platforms aren’t supported exactly? Well here’s your list:

* Cisco SOHO 90 Series

* Cisco 831, 836, and 837 Series

* Cisco 1701, 1711, 1712, 1721, 1751, 1751-V, and 1760 Series

* Cisco 2610XM-2611XM, 2620XM-2621XM, 2650XM-2651XM, and 2691 Series

* Cisco 3631 and 3660 Series

* Cisco 3725 and 3745 Series

* Cisco 7400 Series

* Cisco AS5850 Universal Gateway

Can you explain to me (and any other curious Cisco noobs) what this has to do with dynamips?

From what I see there the 7200's are still okay, so dynamips is off the hook for a little while longer.

1700, 2600, 3600, and 3700 series routers are emulated by dynamips so the emulated routers wouldn't support future versions. But like i said before the 7200 is still supported (I assume) therefore we can always use those in dynamips.

dynamik

What's stopping the them from emulating newer/other routers?

astorrs

Nothing other than a lot of effort.

I still don't see what the big deal would be. It isn't like you HAVE to have the newest and greatest IOS to study for any of the Cisco stuff and I doubt you will need the latest and greatest for quite some time.

I would guess that this is one of Cisco's move to making a new license model for IOS Software. 12.5 May contain the "activation" feature for feature sets.

keenon

this was talked about over a year or 2 ago with them going toward "activation"

Yep, although I give them <6 months before someone umm... "works around this feature", yeah... not that I'm suggesting anyone make use of it when they do, because that would be a violation of the EULA, kinda like running IOS on non-Cisco hardware like dynamips, oh wait...

This is just gear that's being end of life - you don't need to use 12.4 to do CCIE study... 12.2 is fine, most defaults have been set for atleast a few IOS revisions that could majorly affect your lab. At the moment Cisco doesn't care too much about dynamips. The only people that are is CertGuard because it breaks NDA according to them, and a small number of older CCIEs because more people are getting their numbers thanks to the software emulator.

Why do you assume Dynamips is a big problem for Cisco?
The more people comfortable with Cisco IOS the better it is for Cisco.

Those platforms mentioned by the original poster are old and are being phased out, like all older platforms that came before they are being phased out, how do Cisco phase a product out? stop implementing new features, keep creating maintenance releases to fix bugs for current customers for a certain time until the product hits end of life.This is the same for every vendor.

Next generation cisco ios is modular, it looks more like c++ than ios, i doubt the anyones losing sleep over dynamips.

It's simple, really. These devices are aging, and there's newer versions or other models out or coming out to replace them. As they add features to the IOS, like the new ones in 12.5, they have to create hardware to support those features.
