Proxy devices
An FC router achieves inter-fabric device connectivity by creating proxy devices (hosts and targets) in attached fabrics that represent real
devices in other fabrics.
For example, a host in Fabric 1 can communicate with a target in Fabric 2 as follows:
∙ A proxy target in Fabric 1 represents the real target in Fabric 2.
∙ Likewise, a proxy host in Fabric 2 represents the real host in Fabric 1.
The host discovers and sends Fibre Channel frames to the proxy target. The FC router receives these frames, translates them
appropriately, and then delivers them to the destination fabric for delivery to the target.
The target responds by sending frames to the proxy host. Hosts and targets are exported from the edge SAN to which they are attached
and, correspondingly, imported into the edge SAN reached through Fibre Channel routing. The following figure illustrates this concept.
