Abstract
Systems, mechanisms, apparatuses, and methods are disclosed for forwarding Inter-Switch Connection (ISC) frames in a Network-to-Network Interconnect (NNI) topology, for example, via a network switch which includes a first and second physical switch port to receive a first and second physical switch link from a second network switch; logic to implement first and second logical ISC' connections to the second switch via the first and second physical switch links respectively; logic to implement a Primary Forwarder which is interfaced with a Secondary Forwarder in the second switch via the first logical ISC′ connection; logic to implement a Secondary Forwarder which is interfaced with a Primary Forwarder in the second switch via the second logical ISC′ connection; and switch forwarding logic to forward frames based on which connection the frames are received by, and/or based on a gateway identifier associated with each received frame. Other embodiments are disclosed.
