Disable OSPF packet
transmission on a
specified interface
Note:
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 where 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 neighboring relationship can be established on the interface. This enhances
OSPF networking adaptability, thus reducing the consumption of system
resources.
