Abstract
One embodiment of the present invention provides a switch. The switch includes an IP header processor and a forwarding mechanism. The IP header processor identifies a destination IP address in a packet encapsulated with an inner Ethernet header, a TRILL header, and an outer Ethernet header. The forwarding mechanism determines an output port and constructs a new header for the packet based on the destination IP address. The switch also includes a packet processor which determines whether (1) an inner destination media access control (MAC) address corresponds to a local MAC address assigned to the switch; (2) a destination RBridge identifier corresponds to a local RBridge identifier assigned to the switch; and (3) an outer destination MAC address corresponds to the local MAC address.
