In "16.1.1. The next hop calculation" one have:
In the second case, the parent vertex is a network that
directly connects the calculating router to the destination
router. The list of next hops is then determined by
examining the destination's router-LSA. For each link in
the router-LSA that points back to the parent network, the
link's Link Data field provides the IP address of a next hop
router. The outgoing interface to use can then be derived
from the next hop IP address (or it can be inherited from
the parent network).
Suppose that one cannot find any links that points back, is it a good
idea to treat this case as a intervening router:
If there is at least one intervening router in the current
shortest path between the destination and the root, the
destination simply inherits the set of next hops from the
parent.
That is, just inherit the next hops from its parents?
