[c-nsp] ASR920 vs ISR4000

[Tony]

Possibly, except the 4300 seem to be sold with bandwidth limitations.

The 4321 is limited to 50M, upgradeable to 100M.
The 4331 is limited to 100M, upgraeable to 300M.

Means the OP would need to 4331 with the bandwidth upgrade option to get the >100M he was looking for.

It does depend if you're buying new or 2nd hand, but I would think that even purchasing new should be able to get a 2911 for less than 4331 with 300M upgrade option. Although at that low end of the scale, an extra grand or two might not make that much difference.



regards,
Tony.

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.
