depends on what full reachability means to you and whats task previous to
this has instructed you for .
can b possible very much possible that a particular dest is not reachable
via 150.1.1.1 (depends on ur routing section tasks ).
but my point was that for a gre tunnel whatever src and dest u specify ; dts
should be reachabel from src
