Hi All,

I have to install an ASA 5520 and configure approximately 600 Site-to-Site IPSec tunnels. My question is... how much bandwidth is needed for this to work? How much bandwidth approximately consumes each tunnel? Is there a way that I get a number?

Thank you!

The bandwidth on each tunnel can vary. It all depends on how much traffic is being pushed through the tunnels. You can monitor the traffic using SNMP.
