Could you explain why these are undesired to you? Remember I was talking
about fully compliant NET/ROM routing broadcasts sent to a unicast
address. Nothing fishy, except that the destination address is not NODES
but your own NETROM callsign.

Nodes with asterisk in the mnemonic field are never propagated in routing
broadcasts. Also that asterisk is not really the mnemonic. It's just
something the kernel shows when then mnemonic field is _empty_. Anyway
those routes also have quality=0 so they are _not_propagated_.
If you ever see (with listen -a) a NET/ROM routing broadcast with a "*" in
in then that is 100% a bug and you should report it right away (with
details). However I'm pretty sure you won't see that.
If, on the other hand, you see a broadcast with an empty mnemonic field
then that is something I'd like to know more about. I don't think this is
possible either however.
