[c-nsp] ASR920 vs ISR4000

[Nick Cutting]

I agree - and the very fact that when browsing for routers on cisco's website - by default for branch routers -as of a few weeks ago - only the 4xxx and the 8xx are shown.  It's a multitude of clicks to see the ISRg2's.

Check this link - it's the new router performance sheet, I've been using it to size up new client branch routers (well in the last 2 weeks)

A regular googleing turns up the ISRG2 version, not this newer one.

Both of those options are quite probably overkill for what you've described. If a 2811 is currently doing what you need in the deployment and the only change is an increase in speed, just go with the next step up. For what you've described a 2911 would easily fit what you want and I imagine it would be a lot cheaper than either ISR4000 or ARS920. Depends whether you want something new and shiny or something that will just get the job done. If you want to purchase a router now for some future upgrade, then you'd have to take a stab at what you think the upgrade might be and when you think it might happen and then purchase something that you think might be sufficient for that.

Actually price-wise the 4331s are very close in cost to a 2921, and for most workloads, significantly higher performance.  Looking at Cisco's last several generations of branch routers, the performance of the next-gen model one step down is about the same as the previous generation.  So a 2921->4331 for the same price, or a 4321 for the same performance level and less money.

Unless you're buying on the used market or have a very specific need for something only available in the ISR G2 platform, I'd be looking at the ISR 4Ks as a replacement.  I wouldn't be surprised to hear the ISR G2s get announced for EOL in the next 6-12 months looking at Cisco's previous release cycles for branch routers.
