Dell EMC SmartFabric OS10 User Guide Release 10.5.0

A passive interface does not send or receive routing information. Configuring an interface as a passive interface suppresses both receiving and sending routing updates.

Although the passive interface does not send or receive routing updates, the network on that interface is included in OSPF updates sent through other interfaces.

1. Enter an interface type in INTERFACE mode.

   interface ethernet node/slot/port[:subport]

2. Configure the interface as a passive interface in INTERFACE mode.

   ip ospf passive

Configure passive interfaces

OS10(config)# interface ethernet 1/1/6
