What's connected to what, and at what bandwidths?

3560/3750 switches do not support compression.

I think both your routers might support basic compression, but such compression might yield only about 2:1 and without supporting hardware, can be CPU intensive.  Investigate whether there are any WAFS/WAAS add-ons for your routers.

Hi,

We have Point to Point link between headoffice and branch and have Cisco 3650 on Headoffice and Cisco 2811 at branch.ISP provided me dedicated bandwidth on Radio link so I need to compress data on my Point to Point link to use the branch bandwidth more efficiently.

Regards,

Arshad
