Using Demand Circuit Groups with Dial Backup Service
You can use demand circuit groups with dial backup service to dial an alternative
site if the original destination cannot be reached. For information about using
demand circuit groups and dial backup, see “Simplifying Unnumbered
Configurations with Demand Circuit Groups” on page 7-4.
Managing Broadcast Traffic over Demand Circuits
Many of the routing protocols that you can select for a demand circuit send update
packets out to the network. Update packets maintain routing tables and gather
information about network resources. For dial-on-demand, the frequency of these
update packets forces the dial-up connection to remain activated (unless you
configure a time of day to deactivate it). When routers exchange update packets,
the physical connection is established, unless you create a filter.
To reduce this type of traffic, you can configure one of the following:
Static routes
Dial-optimized routing
RIP triggered updates and broadcast timers (for IP)
RIP and SAP broadcast timers (for IPX)
Traffic filters
Each method is described in the sections that follow.
Static Routes
You need to configure the demand circuit protocols so that they do not send
broadcast messages to the network. After you disable broadcast messages, the
router must determine the destination address using a static route.
A static route specifies the transmission path that data must follow to another
network. This path is based on the destination address of the data. Protocols that
can use static routes include:
AURP
