Configure Ospf over On-Demand Circuits

Chapter 8: AI2524 Protocol Configuration Steps

Configure Route Calculation Timers

You can configure the delay time between when OSPF receives a to- pology change and when it starts a Shortest Path First (SPF) calcula- tion. You can also configure the hold time between two consecutive SPF calculations. Type this command in router configuration mode:

timers spf spf-delay spf-holdtime

The OSPF on-demand circuit is an enhancement to the OSPF protocol that allows efficient operation over on-demand circuits like ISDN, X.25 SVCs, and dial-up lines. This feature supports RFC 1793, ex- tending OSPF to Support Demand Circuits.

With this feature, periodic hellos are suppressed and the periodic re- freshes of LSAs are not flooded over the demand circuit.

To configure OSPF for on-demand circuits, perform these tasks:

1.Enable OSPF operation. router ospf process-id

2.Configure OSPF on an on-demand circuit. ip ospf demand-circuit

If the router is part of a point-to-point topology, then only one end of the demand circuit must be configured with this command. However, all routers must have this feature loaded.

If the router is part of a point-to-multipoint topology, only the multi- point end must be configured with this command.

Implementation Considerations

Because LSAs that include topology changes are flooded over an on- demand circuit, it is advised to put demand circuits within OSPF.
