Routing

Routing is the process of directing data packets from their source to their destination across different networks based on IP addresses. Routers are responsible for determining the optimal path for data to travel, using routing tables and algorithms to make decisions. This involves examining the destination IP address of incoming packets and forwarding them through the appropriate network interfaces to reach their final destination. Routing ensures that data is efficiently and accurately delivered, even across complex and large-scale networks. It can involve various protocols such as OSPF, BGP, and EIGRP to manage and optimize routing paths and handle network changes.
