Hi Hussein,
Routing protocols like EIGRP or RIP don’t have the broadcast and non-broadcast network types that OSPF has. By default they use multicast and if you use the neighbor command they switch to unicast traffic only, that’s it.
The next hop will be the Hub router though, you can see see an example here:
