For faster OSPF convergence, you can adjust the following options on the HUAWEI NetEngine80E/40E:

1.Shorten the hello interval and dead interval of the neighbor, or configure Bidirectional Forwarding Detection (BFD) for fast failure detection;
2.Decrease the spf-schedule-interval (five seconds by default) to shorten the time interval between two SPF algorithm operations;
3.Shorten the LSA generation interval;
4.Shorten the interval of detecting LSA arrival;

5.On the interface, run the ospf trans-delay command to speed up the flooding of LSAs.
