It is used for routing the packets hierarchically and it is designed for the following Reasons:
1)Routers need more memory space to store the routing tables.
2)More CPU time needed to scan table.
3)More Bandwidth required to send the scanned report.
So this routing algorithm divides the router into number of routers called regions and maintain tables for them to decrease the size.
this is done in TELEPHONE SYSTEM.
The use of network prefixes in IP addressing enables it to be hierarchical. By subdividing the address space into network and host portions, IP addresses can be aggregated into larger blocks that simplify routing and management of networks. This hierarchical structure allows for efficient routing of data packets across a network.
Distance vector routing is used when the network is simple and has no hierarchical design. Examples of distance vector routing protocols are RIP and IGRP.

Network Admidistrators use routers in large networks for packet filtering, connections between LAN's and WAN's and traffic control. The main benefit of these is that it filters traffic to where if a packet is sent on a local segment it will get discarded if it does not apply to any other devices on the network.
A simple routing table in a computer network is used to determine the best path for data packets to travel from one network device to another. It helps the network devices efficiently route and deliver data to their intended destinations.
Routing strategies refer to the methods used to determine the optimal path for data transmission across a network. Common strategies include static routing, where predetermined paths are used, and dynamic routing, which adjusts paths based on current network conditions. Other strategies include load balancing, which distributes traffic evenly to prevent congestion, and hierarchical routing, which structures the network into layers for efficient management. Each strategy has its advantages and is chosen based on the specific needs and complexity of the network.

When routing tables adapt to network changes the routing system is called adaptive.
Routing refers to the process of selecting paths in a network along which data can travel. In computer networks, it involves determining the best route for data packets to reach their destination, often using routing algorithms and protocols. This ensures efficient data transmission and helps manage traffic within the network. Routing can occur at various layers of networking, with both static and dynamic routing methods available.
