Enabling Dial-Optimized Routing
Dial-optimized routing lets you exchange IP RIP and IPX RIP/SAP routing
updates only when a connection is active. You can enable dial-optimized routing
using only Site Manager; this feature is not configurable using the BCC.
When you enable dial-optimized routing for frame relay demand circuits, you
must also set the Routing Update Hold Time parameter. This parameter instructs
the router to wait for an active connection to the destination device before sending
RIP or SAP routing updates.
This timer is necessary if the UNI between the router and the switch is a dynamic
UNI, which means that the router learns the PVCs when it calls the frame relay
switch. The router contacts the switch for the first time using a statically
configured PVC. If the router sends routing updates over the static PVC, they will
not go over the PVCs that connect to the destination. By setting the Routing
Update Hold Time to a large enough value, you ensure that the updates are sent to
the destination.
For more information about using dial-optimized routing to limit broadcast traffic,
see Chapter 6, “Dial-on-Demand Implementation Notes.”
