A hop. :)
Metrics used by routing protocols are used to determine the best path for routing data packets. Different routing protocols use various metrics such as hop count, bandwidth, delay, load, and cost to make routing decisions. The choice of metric can impact the efficiency and effectiveness of the routing protocol in selecting optimal paths.
RIP (Routing Information Protocol) uses hop count as the metric. It measures the distance to a destination network based on the number of routers (hops) that a packet has to traverse to reach the destination.
It uses hop count in route selection. It is a distance-vector protocol.
You actually cannot make a routing table based on next hop (alone). Next hop is the default gateway ands is always a required part of a route. A route always contains three fields: Network ID, Cost, Next hop.

next hop address
For a hop to another network that is close, if you want it to be a preferred route the cost metric must be a low number. Depending on which protocol you use for routing, this number should be lower than other numbers as alternate routes.
An example of a distance vector routing protocol is Routing Information Protocol (RIP). RIP uses hop count as its primary metric for determining the best path to a destination, with a maximum limit of 15 hops. It periodically shares its routing table with neighboring routers, allowing them to update their own tables based on the received information. This protocol is simple to implement but may have slower convergence times compared to more advanced routing protocols.
it will append the update information to the routing table

A routing table has columns for at least three types of information, Network ID, the Cost and The ID of the next Router called Next Hop.
