Modifying Shortest Path First timers

1. Enter the configure terminal command to access global configuration mode.
   

   device# configure terminal

2. Enter the router ospf command to enter OSPF router configuration mode and enable OSPFv2 globally.
   

   device(config)# router ospf

3. Enter the timers command with the throttle spf keyword and specify the SPF delay, the hold time, and the maximum wait time.
   

   device(config-router-ospf-vrf-default-vrf)# timers throttle spf 100 500 5000

The following example sets the SPF initial delay to 100 milliseconds, the hold time to 500 milliseconds, and the maximum wait time to 5000 milliseconds.

device# configure terminal
device(config)# router ospf 
device(config-router-ospf-vrf-default-vrf)# timers throttle spf 100 500 5000
