passive-interface
Use this command to suppress sending Hello packets on all interfaces or on a specified interface.
This command configures OSPF on simplex Ethernet interfaces. Since a simplex interface represents only one network segment between two devices, configure the transmitting interface as a passive interface. This ensures that OSPF does not send hello packets for the transmitting interface. Both the devices can see each other via the hello packet generated for the receiving interface.
Use the no form with this command to resume sending hello packets on all interfaces, or on a specified interface.
Note: The command passive-interface configures all interfaces as passive. If it is re-applied, the other passive configurations will be removed and all interfaces will become passive again.
