Verifying reachability. From the introduction 'Finally, nodes use the
protocol to actively keep track of which neighbors are reachable and
which are not'. I.e., a router can return a destination unreachable if the
remote router doesn't respond. There is no reason to assume that link state
is reliable or quick.
