If it doesn't work, with the appropriate route, I think I would require
quite some persuading to see why that's not a bug. Similarly, I am
very skeptical that configuring them with an overlapping netmask on
the same interface, if it does not, for example, cause broadcasts to
go to the host address in some cases, is not a bug. Finally, I can
only register my amazement at the implication that someone broke
FreeBSD's routing or input code such that configuring them on the same
interface with the _same_ netmask no longer works. Are all these things
