Invalid Loop
Topology
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. An invalid loop can result in what is
referred to as broadcast storms, where Ethernet frames caught in
repeating cycles can needlessly consume network bandwidth and ‘hang-
up’ the entire network. An example of an invalid loop topology is shown in
Figure 6.
