What Is Overlay Vpn?

Recommended Posts

I have been trying to read about this concept but I can not really understand what is it about. I am clear with remote-access VPN and the IPsec VPN.

 

Please help...

As I understand it you have a CP that provides you with a transport network, ATM for example. You wish to create a VC across the ATM network to another site. The CP will simply carry your VC across without regard to your Layer 3 implementation. In essence you are laying your Layer 3 network on top of a CP's Layer 2 network hence the term overlay.
