thats not quite right - if a node vanishes, then the *routes* reachable via
that note should go away, _not_ the HNA entry itself.
just think about it:
if one would deletes the HNA entry itself then a timed out node, coming
back would need to wait until the HNA entry gets refreshed, rather than
using what he has in its database (and still is valid).
as a further thought experiment you might want to think about a node
that becomes fully isolated (all links down). and now a single link comes
up again - would you flush all contents of the lsdb every originated by
the disconnected node just because of temporary dis connectivity ?
