Dialer Options
Dialer Options
Both ISDN BRI and analog modem interfaces can be configured for
dial-on-demand routing (DDR), which causes the connection to dial out and
become active only under specified circumstances, thus saving connection time
and cost. This window lets you configure options specifying when ISDN BRI or
analog modem connections should be initiated and ended.
Dialer List Association
The dialer list lets you associate the ISDN BRI or analog modem connection with
an ACL to identify interesting traffic. Identifying interesting traffic will cause the
interface to dial out and establish a connection only when the router detects data
traffic that matches the ACL.
Allow all IP traffic
Choose this option to cause the interface to dial out and establish a connection
whenever there is any IP traffic being sent over the interface.
Filter traffic based on selected ACL
Choose this option to associate an ACL, which must be created using the rules
interface, with the interface. Only traffic that matches the traffic identified in the
ACL will cause the interface to dial out and establish a connection.
You can enter the ACL number you want to associate with the dialer interface to
identify interesting traffic, or you can click the button next to the field to browse
the list of ACLs or create a new ACL and choose it.
Timer Settings
Timer settings let you configure the maximum amount of time that a connection
with no traffic stays active. By configuring timer settings, you can have
connections that shut down automatically, saving you connection time and cost.
Idle timeout
Enter the number of seconds that are allowed to pass before an idle connection
(one that has no traffic passing over it) is terminated.
