The only possible > way is like I suggested: ``route add foo/32 -iface bar -cloning''. Yes I know, but ``route add foo -iface bar -cloning`` is meanless, I think, because host route could not be cloned and I kernel should auto set foo to foo/32 because of meanlessness of -host foo. And is route add -host foo -iface bar (without -cloning) could be used for something ? > > <PS> > You still did not tell me what are you trying to do. :-) > </PS> > I'm trying to make routing on FreeBSD as easier and streight forward as it is in cisco's routers(and may be better). :-) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
