VLAN stretched on several site

I have two sites connected by a IPSEC/VPN over InterNet (multi-HDSL on each site).

Each site has Switchs witch several VLANs. each witch different Network address.

What I need now, is to set up one new VLAN that spans the two sites (same VLAN on both sites).

And NOT with MPLS, becouse I allready got IPSEC VLAN.

I know, this my be a BIG problem...

Thanks in advance for any help.

Re: VLAN stretched on several site

Hey claudio

Try to implement dot1q tunneling for this scenarion.see the following link

Re: VLAN stretched on several site

Dot1q isn't going to work here since the connection from site-to-site is layer-3. QinQ assumes a flat vlan topology between sites.

I think L2TPv3 might suit your purposes. Check this link for some cursory details:
