Router-to-PC PPP callback configuration example

Network requirements
As shown in
Configure PPP callback for traditional DDR between the router and the PC. Then, the router can use
the specified dial string to make a return call when the PC calls the router.
Figure 62, the PC obtains its IP address from the router through PPP.
