Processing connect-sequences
1. Check connect-order.
connect-order sequential
3. Check connect-mode. Can the
interface answer or originate a call?
connect-mode either
5. Was the call for connect-sequence
20 successful?
Yes = PPP session begins
No = process connect-sequence 10
up to two more times or until a call is
successful
7. If the demand interface
cannot successfully establish
a call, the router puts it into the
recovery state.

Configuring the idle-timeout Option

You can configure the amount of time that the demand interface remains up
in the absence of interesting traffic. The idle timer helps to keep the backup
connection cost-effective: backup is only active when it is truly necessary. To
decrease your company's costs, you should configure the idle-timeout set-
2. Process connect-sequence 2,
based on connect-order.

4. Was the call successful?
Yes = PPP session begins
No = process connect-sequence 20
6. Based on connect-
sequence attempts command,
repeat steps 2 through 5 until
a call is successful or a
maximum of two more times.

8. In the recovery state, the demand
interface attempts to establish a
connection every 60 seconds.
Based on the configuration, it tries
a maximum of five times. If the
demand interface is not successful,
its status changes to down.
