To avoid wasting network source due to network changes, OSPF defines that the interval for updating LSAs is 5 seconds. In a stable network, if the speed of route convergence is required to be fast, you can cancel the interval for updating LSAs by setting it to 0 seconds. So, routers can detect changes of topology and route in time. This speeds up route convergence. By default, this object is -1, indicating that an intelligent timer is enabled instead. Note that -1 is not a configurable value. Instead, by set the intelligent timer (hwOspfv2LsaOrigMaxIntvl, hwOspfv2LsaOrigStartIntvl, and hwOspfv2LsaOrigHoldIntvl) to default value, it will get back to default configuration.
