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.

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.
In a distance vector routing protocol, such as RIP or EIGRP, each router sends its routing table to neighboring routers. The routers don't know the topology, i.e., how other routers are interconnected. In a link state routing protocol, such as OSPF or IS-IS, routers first exchange information about connections within the network (or an area of the network), and build a topology table. Then each router uses Dijkstra's algorithm to calculate the best route to each destination.
