Configuration Procedure; Configuring Ppp Callback - HP MSR Router Series Wan Access Configuration Manual

HP recommends that you configure the dialer threshold, ppp mp max-bind, and ppp mp min-bind
•
commands on one end of the call. When the configured values are not the same on the two ends
of the call, the following values take effect:
The smaller threshold value.
The smaller upper limit of links.
The greater lower limit of links.

Configuration procedure

To configure MP for DDR:
Step
1. Enter system view.
2. Configure the interval for DDR
to provide traffic statistics.
3. Enter dialer interface view.
4. (Optional.) Set link load
thresholds.
5. (Optional.) Set the upper limit
of links in an MP bundle.
6. (Optional.) Set the lower limit
of links in an MP bundle.

Configuring PPP callback

PPP callback uses the client/server model where the calling party is the callback client and the called
party is the callback server. The client first originates a call, and the server decides whether to place a
return call. If a return call is needed, the callback server disconnects the call and places a return call
according to the username or callback number.
PPP callback has the following benefits:
Enhanced security—The server places a return call to the locally configured number, which prevents
•
caller number spoofing.
Reduced charges—The charge payer can be changed when the charge rates are different in the
•
two directions.
When you configure PPP callback on an interface, follow these restrictions and guidelines:
PPP callback requires authentication. Configure PAP or CHAP authentication on both physical and
•
dialer interfaces on the callback client and server.

The default is 20 seconds.
This command provides traffic
statistics on dialup links for MP.
N/A
By default, no load threshold is set.
The default setting is 16.

By default, the lower limit is 0, and
DDR brings up links depending on
traffic size.
