Spanning Tree Protocol in a Network

Figure A-1 illustrates the use of an VH-8G switch to establish an effective Spanning Tree configuration. Switches A, B and C are connected together in a redundant topology (more than one path between two points). If the connection between A and B goes down, the link between A and C becomes active, thereby establishing a path between A and B through switch C. Additionally, if the connection between B and C goes down, the link between A and C becomes active, establishing a path between B and C through switch A.
