I have 3 sites, A, B and C. A is connected to B and B connected to C via 100Mbps circuits. They are routed links and the routers are 3800 series on each site.
Site A is to be closed and all the servers are moving to the new site C. For many reasons, our client cannot change the IP addresses etc of the servers but needs to phase the migration over a 1 month period before site A closes. Is there any way i can have site A and site C utilising the same subnet passing through site B for this period? Can GRE pick up the broadcast traffic? Is there a Bridging way?
Thanks for your help :-)
