ONFIGURING
DCC
By default, the system does not enable the callback function. Once it is enabled,
the server will originate return calls according to the user name configured in the
dialer route
command.
If the callback client adopts the dynamically assigned network address, the server
will be unable to use the
dialer route
command to configure a callback dial
number to associate with the network address. In this case, the callback client can
only use the
local-user callback-number
command to configure a callback dial
number to associate with the callback user name, and hence determine the
callback reference.
Configuring PPP callback in the resource-shared DCC implementation
1
Configure the PPP callback client in the resource-shared 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 resource-shared DCC are used to implement PPP callback, the PPP
authentication configuration at client end is the same as that of circular DCC,
except that the client in resource-shared DCC implementation must use the
dialer number
command to configure a dial number. See “Configure PPP
callback client in the circular DCC implementation” in Dial-up .
Perform the following configuration in dialer interface view.
