To avoid wasting network resources due to network changes, OSPF defines that the interval for receiving LSAs is 1 second. In a stable network, if the fast speed of route convergence is required, you can cancel the interval of receiving LSAs by setting it to 0 seconds. Routers can thus 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 (hwOspfv2LsaArriveMaxIntvl, hwOspfv2LsaArriveStartIntvl and hwOspfv2LsaArriveHoldIntvl) to default value, it will get back to default configuration.
