Hi group,
 
For disaster recovery, we need to create the same vlan (same ip range) on two seperate geographical locations. Of course, we will have routing problems when these two portions are not linked (bridged) together across a L3 backbone.
Any ideas or suggestions on how to do this ?
- bridging over a GRE tunnel ?
- L2TP ?
 
 
regards,
Geert
