II. Configuring PPP callback in the RS-DCC implementation
1) Configure the PPP callback client in the RS-DCC implementation
As a callback client, a router can originate calls to the remote end (which can be a
router or Windows NT server having the PPP callback server function), and receive the
return calls from the remote end.
When RS-DCC are used to implement PPP callback, the PPP authentication
configuration at client end is the same as that of C-DCC, except that the client in
RS-DCC implementation must use the dialer number command to configure a dial
number. Refer to section 1.2.5 I. 1) "Configure PPP callback client in the C-DCC
implementation".
Perform the following configuration in dialer interface view.
Table 1-18 Implement PPP callback (client configuration) in RS-DCC
Configure the local end to be the PPP
callback client
Disable the local end to be the PPP
callback client
Configure the dialer number for calling a
remote end
Configure the dial number for a Windows
NT server to originate return calls to the
router
Delete the dial number that a Windows
NT server needs for placing return calls
to the router
By default, callback is disabled and no Windows NT server callback dial number is
configured.
2) Configure the PPP callback server in the RS-DCC implementation
When RS-DCC are adopted to implement PPP callback, the PPP authentication
configuration at server end is the same as that of C-DCC, except that the server in the
RS-DCC implementation can only originate a return call according to the dial number
configured in the service-type ppp command. Refer to the section "Configure the PPP
callback server in the C-DCC implementation" in Operation Manual – Dial-up.
Use local-user in system view and service-type ppp in local user view to configure
the callback user and callback dial number, and perform other configurations in dialer
interface view.
