VLAN stretched on several site

battanc · ‎11-21-2008

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.

Hey claudio

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

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:
