Bridge two Switches over Frame Relay.

I am looking for a solution to extend a group of VLANs to another physical location without "loosing" the Layer2 and VLAN tagging so as to be ble to use exactly the same Subnets and IP addressing scheme.

Can I do so using by using 2 routers and a frame relay connection between them?

Regards.

Re: Bridge two Switches over Frame Relay.

Bridging over the WAN may not be the best solution here. To maintain individual VLANs you will need to pass the broadcast domains separately across the Frame Relay. To do this you will need a separate PVC per VLAN. Not only would this be more expensive, but the performance of bridging vs routing will likely be worse too.

Is the distance between locations too far for Gigabit Ethernet service? You could trunk then.
