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.

Classful routing protocols do not carry subnet mask information on their routing updates. This makes them unsuitable for hierarchical addressing that require Variable Length Subnet Mask (VLSM) and discontiguous network. Classless routing protocols do carry subnet mask information on their routing updates.RIP v1 and IGRP are classful routing protocols. RIP v2, EIGRP, OSPF, and BGP are classless routing protocol.When running a classful routing protocol on a network, make sure you use the same subnet mask everywhere. Otherwise, routing black holes can occur.Classless routing protocols extend the standard Class A, B, or C IP addressing scheme by using a subnet mask or mask length to indicate how routers must interpret an IP network ID. Classless routing protocols include the subnet mask along with the IP address when advertising routing information. Subnet masks representing the network ID are not restricted to those defined by the address classes, but can contain a variable number of high-order bits. Such subnet mask flexibility enables you to group several networks as a single entry in a routing table, significantly reducing routing overhead. Classless routing protocols includes RIP v2 and OSPF, Border Gateway Protocol version 4 (BGP4) and Intermediate System to Intermediate System (IS-IS).
it is known as bee routing
Routing is the process that direct a packet to choose an optimal path from source to destination. Routing is of two types static routing and dynamic routing . Dynamic routing is not done manually and uses a number of protocols , it is automatic.
MAC addresses are flat.
Hierarchical routing is a network routing technique that organizes routers and networks into a multi-level structure, allowing for efficient management and communication across large networks. In this approach, routers are grouped into clusters or regions, each responsible for routing within its own area while also connecting to higher-level routers for inter-region communication. This reduces the complexity of routing tables and enhances scalability by limiting the size of routing information that each router must handle. Overall, hierarchical routing improves both network performance and reliability.
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.
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.
The two routing protocols that use a hierarchical network topology are Open Shortest Path First (OSPF) and Enhanced Interior Gateway Routing Protocol (EIGRP). OSPF organizes networks into areas to optimize routing efficiency and scalability, while EIGRP uses a hierarchical approach by grouping networks into subnets for better management and quicker convergence. These protocols help reduce routing overhead and enhance overall performance in large networks.

distribution
A hierarchical addressing scheme organizes addresses in a structured format that reflects the network's topology, allowing for efficient routing and management. It typically involves multiple levels, such as a global prefix for the entire network and subnets for individual segments, enabling easier scalability and administration. Additionally, this approach can help reduce routing table sizes and improve overall network performance by grouping similar addresses together.
For routing huge networks, one should implement a hierarchical routing architecture to reduce complexity and improve scalability. Utilizing protocols like OSPF or BGP allows for efficient path selection and management of large routing tables. Additionally, employing techniques such as route summarization and link aggregation can optimize performance and enhance redundancy. Regularly monitoring and analyzing network performance is also crucial to ensure efficient routing and quick troubleshooting.
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.
There are many companies that provide call routing services. Ring Central and Dial 800 are two such services that a business many take advantage of when it comes to calling.
