The passive state configuration of the OSPF interface.
In the passive mode no OSPF protocol messages are exchanged on
this interface.
true (1) - The interface is configured to work in Passive mode
false (2) - The interface is configured to work in normal mode.
This is the default configuration.
Changing the value will cause OSPF to reset on this interface and
make necessary adjustments to the link state database.
All other operations are not defined and will not affect the state of
the protocol.
