WebOn Cisco IOS 12 and above, the default OSPF LSA group pacing timer is 240 seconds. To change this value, use the timers pacing lsa-group drtn command in router configuration mode, where drtn is a number between 10 seconds and 1800 seconds. This example sets the OSPF LSA group pacing timer to 100 seconds on router R2.
