134you can specify the outgoing interface by an extra command line option
135to disambiguate scoped addresses.
136.Pp
137Scoped addresses are handled specially in the kernel.
138In kernel structures like routing tables or interface structures,
139a scoped address will have its interface index embedded into the address.
140Therefore,
141the address in some kernel structures is not the same as that on the wire.
