Synopsis

no timers spf delay-time hold-time

Configures

OSPF timers

Default

Delay time, 5 seconds; hold time, 10 seconds

Description

This command sets the two types of timers that are important to the OSPF protocol. delay-time is the interval in seconds between the arrival of a topology change and the time OSPF starts the shortest path first (SPF) calculation. hold-time is the minimum interval between two consecutive SPF calculations. Both timers must be in the range 0 to 65,535. Reducing these values may cause the router to switch to a different path more quickly, but this may be a detriment to performance; the SPF calculation is CPU-intensive.
