    You are answering your own question below.

    There is no route for 127.0.0.0/8, only for 127.0.0.1/32. So the default
    route is used.

    If you want 127.0.0.0/8 on lo0, route them there. This has been
    doscussed a while ago on one of the other mailing lists I read, maybe
    BUGTRAQ. Linux has no route for 127.<anything> and does this
    automagically. Solaris follows it's routing table.
