Configure a Router as a Callback Client
Beginning in global configuration mode, configure a router interface
as a callback client:
1. Specify the interface.
interface serial
number
2. Enable DDR. Set parity on synchrono us serial interfaces and asyn-
chronous interfaces.
dialer in-band [no-parity | odd-parity]
3. Enable PPP encapsulation.
encapsulation ppp
4. Enable CHAP or PAP authentication.
ppp authentication {chap | pap}
5. Map the next hop address to the host name an d phone number.
dialer map
protocol

next-hop-address

name

hostname dial-string

6. Enable the interface to request PPP callback for this callback map
class.
ppp callback request
7. (Optional) Configure a dialer hold queue to store packets for this
callback map class.
dialer hold-queue
packets
timeout
seconds
Example: PPP Callback Client
The PPP callback client is configured on an ISDN BRI interface in a
router in Dallas. The callback client does no t require an enable timeout
and a map class to be defined.

ip address 7.1.1.8 255.255.255.0
