NT server-to-router PPP callback configuration example

Network requirements
As shown in
Configure PPP callback for traditional DDR between the router and NT server. Then, the NT server can
use the specified dial string to make a return call when the router calls the NT server.
Figure 65 Network diagram
Configuring the router
# Create dialer group 1 and configure a dial rule for it.
<Router> system-view
[Router] dialer-group 1 rule ip permit
# Create a local user userpc for the PC, and configure the service type as PPP.
Figure 65, the router obtains its IP address from the NT server through PPP.
