I have a VPN over ipsec established between 2 sites (site 1 and site 2) with Cisco 871.
Please see my network diagram : http://img806.imageshack.us/img806/9821/img007.jpg
I created vlan on my 3com switches.
Now, I would like to keep VLAN's between site 1 and site 2.
If I am vlan1/site1, after the VPN, I will be always in the vlan1/site2 and vlan2/site1 -> vlan2/site2.
Is it possible ?
I'm looking for something like that on google, and I find : "dot1q tunneling"
