| Connections initiated by remote
offices or telecommuters are brought up on an as-needed basis,
resulting in substantial cost savings for the company. In DDR
scenarios, users are not connected for long periods of time. The
number of remote nodes requiring access is relatively low, and the
completion time for the dial-in task is short.
A spoke router is the link between a
stub network and the WAN. A stub network has only a single
connection to a router. Following are the steps involved in
configuring a spoke router for DDR.
- Define what constitutes interesting traffic by using the
dialer-list command.
- Assign this traffic definition to an interface by using the
dialer-group command.
- Define the destination address, hostname, telephone number to dial, and optional call parameters by using the
dialer map
command.
Define call parameters by using commands such as
dialer idle-timeout,
dialer fast-idle, and
dialer load-threshold.
