Abstract
There is described a Layer 3 router and method for routing PRP frames. A first frame is received at one or more ports of the Layer 3 router. A PRP suffix of the first frame, a source MAC address of the first frame, and a Redundancy Control Trailer of the first frame are identified. The first frame is forwarded to a routing subsystem of the Layer 3 router, and a second frame including a source IP address is received from the routing subsystem. The source MAC address of the first frame is assigned to the second frame in response to associating the source IP address with the source MAC address, and the Redundancy Control Trailer is appended to the second frame. The second frame is transmitted from the port or ports of the Layer 3 router.
