Use the command... RemarksEnter system view system-view —Enter OSPF view ospf [ process-id [ router-idrouter-id ] ] —Disable OSPF packettransmission on a specifiedinterfacesilent-interfacesilent-interface-typesilent-interface-numberRequiredBy default, all the interfaces areallowed to transmit OSPFpackets.z On the same interface, you can disable multiple OSPF processes from transmitting OSPF packets.The silent-interface command, however, only applies to the OSPF interface on which thespecified process has been enabled, without affecting the interface for any other process.z After an OSPF interface is set to be in silent status, the interface can still advertise its direct route.However, the Hello packets from the interface will be blocked, and no adjacencies can beestablished on the interface. This enhances OSPF networking adaptability, thus reducing theconsumption of system resources.Configuring OSPF AuthenticationFollow these steps to configure OSPF authentication:To do...
