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.

When should distance vector routing be used?
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.
In a three-layer hierarchical network design which distribution layer function delineates broadcast domains?
routing between VLANs
What are advantage of hierarchical routing?
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.
Which two benefits are provided by using a hierarchical addressing network addressing scheme?
1- Reduces routing table entries 2- Ease of management and troubleshooting.
Internet routing with a network's internal routing?
internal Network
Which hierarchical design model layer controls the flow of network traffic using policies and delineates broadcast domains by performing routing functions between virtual LANs?
distribution

When routing tables adapt to network changes the routing system is called?
When routing tables adapt to network changes the routing system is called adaptive.
Why is layer three addressing hierarchical?
Layer 3 addressing is hierarchical because it allows the division of networks into subnets. For example, one route entry can refer to a large general network and another can refer to a subnet of that same network. When forwarding a packet, the router will select the most specific route that it knows. However, if a specific subnet is not in the routing table but the larger network that holds the subnet is known, then the router will send it to the larger network, trusting that another router will find the subnet.
Explain any two dynamic routing algorithms?
Dynamic or adaptive Routing algorithms in contrast change their routing decisions to reflect changes in topology and usually the traffic as well Dynamic routing attempts to solve this problem by constructing routing tables automatically, based on information carried by routing protocols, and allowing the network to act nearly autonomously in avoiding network failures and blockages. Dynamic routing dominates the Internet. However, the configuration of the routing protocols often requires a skilled touch; one should not suppose that networking technology has developed to the point of the complete automation of routing.
What is ad hoc mode?
Ad hoc mode is A wireless network is a decentralized wireless network. The network is is call an ad hoc network because each computer forwards data for other computers. Wired networks use routers to perform the task of routing data from on computer to another.
What is layered network?
A layered network, or a network layer, is the set up of how data is sent over a network. Each layer has it's own responsibility by either capturing the data or routing it to a computer on the network.
