A corporate policy requires PPPoE to be enabled and to maintain a connection with the ISP, even
if no interesting traffic exists. Which feature can be used to accomplish this task?
A.
TCP Adjust
B.
Dialer Persistent
C.
PPPoE Groups
D.

The “dialer persistent” command (under interface configuration mode) allows a dial-on-demand routing (DDR) dialer profile connection to be brought up without being triggered by interesting traffic. When configured, the dialer persistent command starts a timer when the dialer interface starts up and starts the connection when the timer expires. If interesting traffic arrives before the timer expires, the connection is still brought up and set as persistent. An example of configuring is shown below:
interface Dialer1
ip address 12.12.12.1 255.255.255.0
encapsulation ppp
dialer-pool 1
