In designing a network topology, be sure your topology does not contain any
loops. A loop exists when there is more than one path between any two end
nodes in your network. A loop can result in what is referred to as broadcast
storms, where Ethernet frames become caught in repeating cycles that
needlessly consume network bandwidth. This often results in poor network
performance. An example of an invalid loop topology is shown in Figure 7.
