Patent ID: 10237083

Abstract:
In an approach to routing and forwarding a data packet with a forwarding RBridge and a corresponding RBridge, a computer, in response to receiving a TRILL data packet, performs the following steps: parsing a TRILL header of the TRILL data packet, and acquiring an egress RBridge nickname of the TRILL data packet; obtaining routing information corresponding to the egress RBridge nickname, wherein the information indicates whether the forwarding RBridge is the penultimate hop RBridge on the forwarding path to which the egress RBridge nickname is corresponding; and in response to the indication in the information that the forwarding RBridge is the penultimate hop RBridge on the forwarding path to which the egress RBridge nickname is corresponding, stripping the TRILL header of the TRILL data packet off to obtain an original data packet, and forwarding the original data packet to the egress RBridge from an out port specified by the information.
