Answer: Point-to-point topology
Explanation:Point-to-point topology is the connection between the nodes in a simple/regular manner by establishing only one path for the communication with each other.The flow that occurs in this type of topology are of two types - bidirectional(two-way) and unidirectional(one-way) .
Thus the topology for the communication of the routers through a single communication path is done with the help of point-to-point pattern , considering each router as a point/node.
The correction is *regular.
