Run the command set protocols ospf passive-interface to the set specified layer 3 interface (s) as passive OSPF interfaces. To set all interfaces as passive, you can use the keyword default. To selectively choose an interface to set as passive interface, specify the interface name. The The optional parameter vrf can be used to specify the VRF for this command to take effect in, if not specified the command affects the default VRF.
Passive interfaces do not take are part in OSPF calculations nor do they of OSPF database but they do not send or receive OSPF LSAs and hence adjacencies are not formed on these interfaces.
To delete the configuration, run the command delete protocols ospf passive-interface.
