AB This article describes a scalable, self-configuring architecture for campus networks, the ABridges architecture. It is atwo-tiered hierarchy of layer two switches in which network islands running independent rapid spanning tree protocolscommunicate through a core formed by island root bridges (ABridges). ABridges use AMSTP, a simplified and self configuringversion of MSTP protocol, to establish shortest paths in the core using multiple spanning tree instances, oneinstance rooted at each core edge ABridge. The architecture is very efficient in terms of network usage and path lengthdue to the ability of AMSTP to provide optimum paths in the core mesh, while RSTP is used to aggregate efficientlythe traffic at islands networks, where sparsely connected, tree-like topologies are frequent and recommended. Convergencespeed is as fast as existing Rapid Spanning Tree and Multiple Spanning Tree Protocols.
