Hi Tod,
 From other messages, it does sound like we can ignore the
169.254.0.0. I guess I should have specified that 169.254.0.0 is a
network address, and not a host address. Most routes are to
networks, and not specific hosts. You can specify the route to a
specific host as well. But it usually isn't needed unless you have a
point to point connection.
