You can configure the interface so that the receiving and sending of OSPF packets are prohibited, and thus the networking adaptability of OSPF is enhanced and system resource consumption is reduced.
To prevent OSPF routing information from being acquired by the routers on a certain network, and prevent the local router from receiving the route updates advertised by other routers, use the silent-interface command to suppress the interface from receiving and sending OSPF packets.
Different processes can suppress the same interface from sending and receiving OSPF packets, but the silent-interface command is valid only for the OSPF interface on which the specified process has been enabled, and has no effect on the interface of other processes.
After an OSPF interface is set to be in silent status, the interface can still advertise its direct route. However, the Hello packets of the interface are blocked, and no neighbor relationship can be established on the interface. Hence, the OSPF capability to adapt to the networking is enhanced, which in turn reduces the consumption of system resources.
