Yes, routers can communicate with each other to exchange information about network paths and manage data traffic. This communication typically occurs through routing protocols, such as OSPF (Open Shortest Path First) or BGP (Border Gateway Protocol), allowing routers to share routing tables and optimize data transmission across networks. By collaborating in this way, routers ensure efficient routing and help maintain network reliability.
