is it possible to combine L2TP and GRE?

Is it possible to combine L2TP and GRE?

ie using using a switch port configured with L2TP as the source interface for GRE and so that i have a L2TP tunnel built under a GRE tunnel so that I transmit vlans over the internet?

Re: is it possible to combine L2TP and GRE?

No you can't. GRE is only designed to carry routing protocols and multicast traffic over VPNs.

It is also bad design practise to design a network that carry's L2 vlan's over a WAN or internet link.

You have to ask yourself why you would want to carry VLANs over VPNs?

Hope this helps.
