When the router has established neighbor relationships with multipleneighboring routers, and the routing table size is big, the router must receive and process largenumbers of packets. Configuring OSPF to give priority to receiving and processing hello packetshelps ensure stable neighbor relationships.To do… Use the command… RemarksStep 1 Enter system view system-view —Step 2 Configure OSPF to givepriority to receiving andprocessing hello packetsospf packet-processprioritized-treatmentRequiredNot configured by defaultConfiguring the LSU transmit rateSending large numbers of LSU packets for LSDB synchronization with neighbors may affect routerperformance and consume large network bandwidths. Therefore, you can configure the router tosend LSU packets at intervals and limit the maximum number of LSU packets sent out an OSPFinterface each time.You can configure the interval that an OSPF interface sends LSU packets and the maximumnumber of LSU packets the interface sends at each interval.
