Hi

personally I don't think you can answer that question with what you have provided without testing it , you should be specking the amount of traffic that's going to be sent through the devices rather the features being used and what the overhead etc will be when using tunnels , the current ISP connections your using , the mount of servers /users and the type of traffic there sending

using that image with those features is just standard its what your going to be doing and pushing through them that may cause an issue if not properly specked out

Hi Imran

Take a look at a recent post:

The Cisco Live presentation covers various real-life scenarios.

29xx is past "End of Sale". If you are in the design phase, please consider proposing from the ISR/4000 series OR the ASR/1000/1000-X series which are likely to serve you will.

I hope this helps ... Palani
