Spanning Tree Protocol Support
IBM initially supported only source route bridging (SRB) in its bridges, so most networks were built to use it. The main consideration for SRB implementations in switches is the spanning tree algorithm for spanning tree explorers (STEs). IBM originally implemented a form of the Institute of Electrical and Electronics Engineers (IEEE) spanning tree algorithm. This algorithm, commonly referred to as the IBM spanning tree, limits the STE frames to one copy per destination ring. Some SRB implementations have also implemented the IEEE Spanning Tree Protocol to be compatible with source route transparent bridges. The IEEE Spanning Tree Protocol is not compatible with the IBM Spanning Tree Protocol.
