here is the scenario. My customer is currently moving its head office location to a temporary one to refurbish the existing building. We need to move all servers etc to this new location in a timely fashion without disruption. we have four VLANS in the current network and at this time our WAN provider cannot pass VLANS through thier WAN infrastructure.
the question is, how can we work around this temporarily (We need to maintain exact ip addressing, gateway etc as if they were in the existing location) the time to completely move from one location to the other is about two months, meaning every week, one or two servers will be moving.
we were thinking of two options,
1. bridged network - not too sure about the vlans
2. enable single WAN ports for each VLAN - very very expensive
You can try with bridging over GRE tunnels. The details for the config depends on you exact setup, but generally you will need one separate tunnel for each vlan (use tunnel id to differentiate). It can be a little tricky to setup, but should work.
Per your requirements l2tp is the technology you should be looking into. What type of router are you using to terminate you want connections (on both locations). There are limitations l2tp depending on the hardware you are using.
If you are still working on this. The GRE tunnel is a great idea (perhaps with vrfs). Otherwise if security is not a priority over the WAN, sub-interfaces would for you. You can just re-create the VLANs on the remote side and match them (if you must).
