VPN within a ATM PVC

Hi,

Is it possible to configure a 72xx router with site-site VPN through a ATM PVC ?

Any sample configuration?

Re: VPN within a ATM PVC

It is possible, and attached is a sample configuration (cut down version for confidentiality) for a star topology network.

Each PVC is mapped to a different subinterface and static routes are used here, but you can substitute with whichever routing protocol.

The CoS used in this example is VBR-nrt.
