Usage guidelines
A dial rule determines when an interface initiates DDR calls. You need to configure dial rules only on
the initiator of DDR calls.
You can configure a dial rule to match only IP packets or use an ACL to match packets.
Permitted protocol packets or packets that match a permit statement of an ACL are interesting
packets. When receiving an interesting packet, DDR performs one of the following operations:
• Sends it out and resets the idle-timeout timer if a link is present.
• Originates a new call to establish a link if no link is present.
Denied protocol packets or packets that match a deny statement of an A CL are uninteresting
packets. When receiving an uninteresting packet, DDR performs one of the following operations:
• Sends it out without resetting the idle-timeout timer if a link is present.
• Drops it if no link is present.
For DDR to forward packets correctly, you must configure a dial rule and associate it with the dialup
interface by using the dialer-group command.
