Figure 1-22 illustrates the case where the user configures all switches in the same
Circuit Saver LAN.
Figure 1-22. Single Circuit Saver LAN (Token Ring Example)
This configuration allows direct ATM forwarding between any two of the
switches with better performance, but it requires more circuits to be set up.
Figure 1-23
illustrates an Ethernet configuration where the user wants the fewest
circuits to be used. With fewer circuits, performance is lower.
