l Interruption of Telnet services
In Telnet connection, you can use two types of shortcut keys to interrupt the connection.
As shown in Figure 8-4, Router A logs in to Router B through Telnet, and Router B logs
in to Router C through Telnet. Thus, a cascade network is formed. In this case, Router A
is the client of Router B and Router B is the client of Router C. Figure 8-4 illustrates the
usage of the two types of shortcut keys.
