To configure demand routing for a primary ISDN module, you must complete
the following steps:
1. Create an extended access control list (ACL) to define the traffic that will
trigger the dial-up connection.
2. Configure a demand interface.
3. Configure the BRI interface.
4. Configure an ISDN group.
5. Create a static route to the far-end network.

Define the Traffic That Triggers the Connection

When configuring demand routing, you must define the interesting traffic—
the traffic that triggers, or activates, the WAN connection. For example, if
you are configuring demand routing for an ISDN connection between the
main office and a branch office, the interesting traffic would be the packets
destined for the branch office. (See Figure 8-6.)
