This is a bug in in NetView - it will not change the status of those unnumbered
IP subinterfaces! If the router actually goes down (i.e. unplugged from the
network), NetView will change the node to a marginal status (yellow), as those
IP unnumbered (0.0.0.0) interfaces will stay green (there is apparently no way
to get the status).
There is an APAR opened on this: IX81136
I have resorted to unmanaging those interfaces, as we had some routers reload
and never saw it since the unnumbered sub-interfaces never changed color, hense
we never received a Node Down event.
