Setting the convergence priority for OSPF routes

To set the convergence priority of OSPF routes based on a specified IP prefix list takes effect on the public network only.

OSPF route calculation, link-state advertisement (LSA) flooding, and LSDB synchronization can be implemented according to the configured priority. Therefore, route convergence can be controlled.

When an LSA meets multiple priorities, the highest priority takes effect.

OSPF calculates LSAs in the sequence of intra-area routes, inter-area routes, and AS external routes. This command enables OSPF to calculate the three types of routes separately according to the specified route calculation priorities. Convergence priorities are critical, high, medium, and low. To speed up the processing of LSAs with the higher priority, during LSA flooding, the LSAs need to be placed into the corresponding critical, high, medium, and low queues according to priorities.
