When a router learns routes to remote networks from other routers in a network?

When a router learns routes to remote networks from other routers, it typically uses routing protocols such as OSPF, EIGRP, or BGP. These protocols facilitate the exchange of routing information, allowing routers to share and update their routing tables dynamically. As a result, routers can determine the best paths to reach various networks, ensuring efficient data packet delivery across the network. This process is essential for maintaining optimal network performance and connectivity.
