Spanning Tree Protocol in a Network
A-2 Spanning Tree Concepts
A.2 SPANNING TREE PROTOCOL IN A NETWORK
To provide a simple generic example, three standalone switches are shown in Figure A-1 to
illustrate how the switches would establish an effective STA 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.
