No, it is not necessary to set up that address on that interface in order to
use that rule and send out packets with that source address.
However, if you send out packets with that source address, and you want to
receive the replies, the address must exist on whatever machine the address
will get routed to.
If you are only doing UDP transmits, and never expect a reply, it might work.
