However, if STP is activated on both switches, broadcast and multicast packets would
be transmitted as shown in Figure 8.1b. To provide this desired path redundancy, as well
as preventing bridging loops, STP defines a tree that spans all switches in an extended
network. STP forces certain redundant data paths into a blocked state, leaving others in
the forwarding state. If a link in forwarding state becomes unavailable, STP will
reconfigure the network and re-route the data paths by activating the appropriate
standby paths.
