1. A method for forwarding Fibre Channel over Ethernet (FCoE) and FCoE Initialization Protocol (FIP) frames over a Transparent Interconnection of Lots of Links (TRILL) network by a plurality of FCoE device interconnection apparatus (FIA) under control of an FIA Controller, from a first FCoE device to a second FCoE device, the method comprising:
receiving an incoming frame from the first FCoE device at a first FIA and determining if the frame is a FCoE frame or a FIP frame, if the frame is a FCoE frame,
the frame including at least a destination address of a destination Ethernet Media Access Control (MAC) address of the FIA controller and a source Ethernet MAC address, replacing the destination Ethernet MAC address of the incoming FCoE frame with a destination Ethernet MAC address of the second FCoE device, or if the frame is a FIP frame,
forwarding the frames with their original destination and source Ethernet MAC addresses of the FIP frame, and for both a FCoE frame and LIP frame:
replacing the source Ethernet MAC address of the incoming FCoE frame,encapsulating the frame in a TRILL header,forwarding the frame to an egress FIA,decapsulating at the egress FIA the frame into a decapsulated FCoE frame, andforwarding the decapsulated FCOE frame to the second FCoE device. |
