You are right, the true next hop is known. But for the receiving system, in classic RIP the correct next hop is the sender of the RIP message since the sender adverises its routes via the sending interface as a gateway for those routes. The "previous next hop" is used for optimisations/loop avoidance and other internal stuff.

If the true next hop is known then why does ripd not use it? what is the rfc compliant and thus proper behavior for how and where packets are sent on to when using rip?
