Disabling OSPF Packet Transmission on an Interface

To prevent OSPF routing information from being acquired by the routers on a certain network, use the
silent-interface command to disable OSPF packet transmission on the corresponding interface.
Follow these steps to disable OSPF packet transmission on an interface:
To do...
Enter system view
Enter OSPF view
Disable OSPF packet
transmission on a specified
interface
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 the
specified process has been enabled, without affecting the interface for any other process.
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 be
established on the interface. This enhances OSPF networking adaptability, thus reducing the
consumption of system resources.

Configuring OSPF Authentication

Enter system view
Enter OSPF view
