Hop in a path from the source to the destination is assigned a hop-count value, which is typically 1. When a device receives a routing update that contains a new or changed destination network entry, the device adds 1 to the metric value indicated in the update and enters the network in the routing table. The IP address of the sender is used as the next hop. If an interface network is not specified in the routing table, it will not be advertised in any RIP update. RIP Versions The original version of Routing Information Protocol (RIP), is known as RIP Version 1 (RIPv1). The specification of the RIP, defined in RFC 1058, uses classful routing. Periodic routing updates do not support variable length subnet masks (VLSM) because periodic routing updates do not contain subnet information. All subnets in a network class must be of the same size. Because RIP, as per RFC 1058, does not support VLSM, it is not possible to have subnets of varying sizes inside the same network class. This limitation makes RIP vulnerable to attacks. To rectify the deficiencies of the original RIP specification, RIP Version 2 (RIPv2), as described in RFC 2453, was developed. RIPv2 has the ability to carry subnet information; thus, it supports Classless Inter-Domain Routing (CIDR). Exchange of Routing Information Routing Information Protocol (RIP) is normally a broadcast protocol, and for RIP routing updates to reach nonbroadcast networks, you must configure the Cisco software to permit this exchange of routing information. To control the set of interfaces with which you want to exchange routing updates, you can disable the sending of routing updates on specified interfaces by configuring the passive-interface router configuration command. You can use an offset list to increase increasing incoming and outgoing metrics to routes learned via RIP.. VLSM Calculator for Android, free and safe download.

Resumo: Você já ouviu falar do VLSM? O que isso representa? O artigo de hoje fornecerá informações detalhadas sobre o VLSM.ÍndiceDefinição de VLSMProcesso de Implementação de VLSMVLSM VS FLSMConclusãoDefinição de VLSMVLSM, que significa máscara de sub-rede de comprimento variável, ocorre quando o design de sub-rede usa várias máscaras na mesma rede. Isso significa que mais de uma máscara é usada para várias sub-redes de uma rede ou uma única classe A, B, C.O VLSM é equivalente a sub-redes de sub-redes, o que significa que o VLSM permite que os engenheiros de rede dividam o espaço de endereço IP em hierarquias de sub-redes de tamanhos diferentes. Portanto, o VLSM permite que os engenheiros de rede criem sub-redes com contagens de host variadas, com apenas um pequeno número de endereços sendo desperdiçados.O VLSM é usado para aumentar a disponibilidade de sub-redes porque as sub-redes podem ter tamanhos variáveis. Também é definido como um processo de criação de sub-redes para uma sub-rede.Processo de Implementação de VLSMNo VLSM, as sub-redes usam tamanhos de bloco conforme necessário, portanto, a sub-rede precisa ser usada várias vezes.Se o administrador tiver o IP 192.168.1.0/24, você pode atribuir o IP inteligente do departamento seguindo estas etapas:Passo 1. Para cada segmento, selecione o tamanho do bloco, que é maior ou igual ao requisito real. O requisito essencial é a soma do endereço do host, endereço de broadcast e endereço de rede. Listar sub-redes possíveis:Passo 2. Organize todos os segmentos em ordem decrescente de acordo com o tamanho do bloco, do

Maior para o menor requisito.Etapa 3. O maior IP disponível deve ser atribuído ao requisito mais alto, para que Vendas e Compras recebam 192.168.1.0/25.Passo 4. O próximo segmento requer IP para lidar com 50 hosts. A sub-rede IP com número de rede 192.168.1.128/26 é a segunda mais alta e pode ser atribuída a 62 hosts.Etapa 5. A próxima sub-rede IP 192.168.1.192/27 atende aos requisitos do departamento de contas porque tem 30 IPs de host válidos que podem ser atribuídos a 26 computadores.Etapa 6. O último segmento precisa de 5 IPs de host válidos e a sub-rede 192.168.1.224/29 atende a sub-rede, com uma máscara de 255.255.255.248, conforme necessário.VLSM VS FLSMSub-redes: No VLSM, as sub-redes são de tamanho variável, com um número variável de hosts, tornando o endereçamento IP mais eficiente. Mas no FLSM, todas as sub-redes são iguais em tamanho com um número igual de hosts.Resíduos de endereços IP: O VLSM desperdiça menos endereços IP do que o FLSM.Os endereços IP correspondentes: VLSM é a melhor escolha para endereços IP públicos, enquanto FLSM é a primeira opção para endereços IP privados.Uso de máscara de sub-rede: O VLSM usa várias máscaras de sub-rede, enquanto o FLSM usa a mesma máscara.Configuração e gerenciamento: O VLSM é simples na configuração e no gerenciamento, mas o FLSM é complicado.Protocolos de roteamento: O VLSM oferece suporte a protocolos de roteamento classless, enquanto o FLSM oferece suporte a protocolos de roteamento classless e classful.ConclusãoVLSM é uma tecnologia crítica no projeto de rede moderno.

Where they’re most needed. However, VLSM can complicate network management due to the varying sizes of each subnet. Network administrators must keep track of these different subnet sizes, which can add complexity to configuration and monitoring tasks. This extra layer of complexity requires more diligent documentation and potentially more advanced management tools to ensure all devices are correctly configured.Subnetting with CIDR:CIDR is a modern method of subnetting that offers flexible allocation of IP addresses without being restricted to the traditional class-based system. It allows network administrators to create subnets of various sizes by using a notation (e.g., /24, /16) to indicate how many bits are used for the network prefix. This flexibility optimizes IP address utilization and improves routing efficiency. For example, CIDR notation allows for the creation of very small subnets when necessary, which can be particularly helpful in managing the IP address space in organizations with diverse needs across different departments.Type of SubnettingDescriptionProsConsFixed-Length SubnettingSubnets are all the same size.Simplifies network management and planning.May waste IP addresses if some subnets need more.Variable-Length Subnetting (VLSM)Subnets can vary in size according to need.Optimizes IP address usage, allowing efficient allocation.More complex to manage due to varying subnet sizes.Subnetting with CIDRFlexible IP allocation without traditional class constraints.Improves routing efficiency and maximizes address space.Requires understanding of CIDR notation, which can be complex for beginners.Subnetting tools and resourcesWhen it comes to managing subnets effectively, several tools can help streamline the process and minimize errors. These tools are essential for network administrators who want to optimize IP address allocation and efficiently manage their network infrastructure efficiently. Subnet calculatorsSubnet calculators are invaluable tools that automatically calculate subnets based on the provided IP address and subnet mask. These calculators help network administrators quickly determine how many addresses are available within a subnet, the range of usable IP addresses,.
