In the aftermath of Hurricane Ike, I had to move a bunch of servers and users from our Galveston office to a remote site in another city. Normally Galveston and the remote site is connected with a point-to-point T-3. To simplify and hasten getting everything up and running, I setup 3 new Vlans at the new site and duplicated the subnets from the Galveston site, so I wouldn't have to readdress the moved equipment.
Now, the T-3 is backup and they want to start moving everything back to Galveston. Is there an easy way to temporarily bridge the Vlan's at the remote site with the actual Vlans in Galveston? If so, I can move things back to Galveston gradually, otherwise, I'll have to shut everything down, pack everything up and take it back and set it all up.
Even if it's a unsupported hack I don't mind, it'll only be for a few day.
