RSTP Applications
The following sections describe various applications of RSTP:
• Section 5.34.2.1, “RSTP in Structured Wiring Configurations”
• Section 5.34.2.2, “RSTP in Ring Backbone Configurations”
• Section 5.34.2.3, “RSTP Port Redundancy”
Section 5.34.2.1
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 817 would leave all the ports of
bridges 555 through 888 connected to the network.
