Abstract
An electronic device that includes a stack of multiple computer network devices (such as switches) that implement a spanning tree using a distributed spanning tree protocol (STP) is described. A given computer network device may create a virtual internal stacking port. This virtual internal stacking port is included in the spanning tree and provides stacking interface logic that allows the given computer network device to connect to a virtual hub in the stack that is common to the multiple computer network devices. Moreover, the given computer network device may run an instance of the distributed STP that controls ports in the given computer network device, where the instance of the distributed STP run by the given computer network device uses a bridge identifier that is common to the multiple computer network devices.
