Marks all OSPFv2 and OSPFv3 interfaces passive by default.
OSPF router configuration mode
OSPFv3 router configuration mode
OSPF router VRF configuration mode
OSPFv3 router VRF configuration mode
When you configure the interfaces as passive, the interfaces drop all the OSPFv2 and OSPFv3 control packets.
You can use the ip ospf active and ip ospf passive commands in interface subconfiguration mode to change active/passive state on specific OSPFv2 interfaces. You can use the ipv6 ospf active and ipv6 ospf passive commands in interface subconfiguration mode to change the active and passive state on specific OSPFv3 interfaces.
The no form of the command disables the passive state.
The following example marks all OSPFv2 interfaces as passive.
device# configure terminal device(config)# router ospf device(config-router-ospf-vrf-default-vrf)# default-passive-interface
