RSTP in Structured Wiring Configurations
RSTP may be used to construct structured wiring systems where connectivity is maintained in the event of link
failures. For example, a single link failure of any link between A and N in Figure 37 would leave all the ports of
bridges 555 through 888 connected to the network.
