Routing in an internet, the goal of the network layer is to deliver a datagram from its source to its destination or destinations. if a datagram is destined for only one destination (one to one delivery), we have unicast routing. if the datagram is destined for several destinations (one to many delivery), we have multicast routing.

Computer Networks And Internet Protocol Unit 7 Week 5 Pdf This gives a two level routing algorithm: within each network an interior gateway protocol is used, but between the networks, an exterior gateway protocol is used (''gateway'' is an older term for ''router''). Routing is the concept of applying strategies and running routing protocols to create the decision making tables for each router. these tables are called as routing tables. forwarding can be defined as the action applied by each router when a packet arrives at one of its interfaces. Internet routing tables are initialized by hosts from a configuration file at system startup, and system administrators seldom make routing changes during normal operations.gateways exchange routing information periodically to accomadate network changes and keep their. Open shortest path first (ospf) is a unicast routing protocol developed by working group of the internet engineering task force (ietf). it is a intradomain routing protocol.

Layer 3 protocol that forwards datagrams across internet ! uses routing tables prepared by routing protocols, e.g., open shortest path first (ospf), routing information protocol (rip) !. The document discusses the functions and services of the network layer, which is responsible for routing, logical addressing, and internetworking. it explains key concepts such as point to point communication, network addressing, and classful addressing, detailing classes a, b, c, d, and e of ip addresses. The document discusses key topics related to the network layer, including routing algorithms, congestion control, quality of service, and internetworking. it describes shortest path routing algorithms like dijkstra's algorithm and bellman ford algorithm. The routing tables are normally dynamic and are updated using routing protocols. figure shows a part of the internet that uses routers to connect lans and wans.
