Laboratório EIGRP – Sucessor, FS e tabela de TopologiaEIGRP Lab – Successor, FS and topology table

Olá Pessoal,

Fiz este laboratório para podermos entender como funcionam as diferenças entre as tabelas de roteamento e a de topologia do protocolo EIGRP.

O laboratório consiste em modificar as larguras de banda dos enlaces, para monitorar o resultado na tabelas topológica e de roteamento e verificar a convergência entre estas.

O download do laboratório com as configurações utilizadas pode ser feito aqui abaixo:

Um abração pessoal,

Maurício.Hello Guys,

I did this lab to understand how we can work the differences between the routing tables and topology of the EIGRP protocol.

The laboratory is to modify the bandwidth of links, to monitor the result on the topological and routing tables and check the convergence between them.

Download the lab with the settings used can be done here below:

Laboratório OSPF – Convergência DR & BDROSPF Lab – DR & BDR Convergence

Olá pessoal,

Faltando apenas uma semana para o grande dia, estou praticando bastante minhas habilidades práticas nos temas que senti que precisava de um reforço.

Um destes era como funcionava a convergência do protocolo OSPF em redes multi-acesso e a relação dos Routers IDs com a escolha do DR e do BDR da rede.

O laboratório foi feito para que se possa ver a convergência da rede quando esta sobre uma modificação.

Nota-se que cada segmento multi-acesso possui a eleição de um DR e/ou BDR, logo, para as redes que possuem apenas um dispositivo, esta terá somente um DR e nenhum BDR.

A respeito do Router ID, este é o maior IP numa interface lógica (loopback). Se não existir uma interface lógica, o RID é definido como o maior endereço IP  de uma interface participante no processo de roteamento.

O download pode ser feito abaixo:

Um abração pessoal,

Hello staff,

With only a week for the big day, I’m practicing my very practical skills in areas I felt I needed a backup.

One of these was how the convergence of OSPF protocol in multi-access networks and the IDs of the routers with the choice ofDR and BDR on the network.

The laboratory has been done so you can see the convergence of the network when it on a modification.

Note that each multi-access segment has the election of a DR and / or BDR, so for the networks that have only one device, this will take only a DR and BDR no.

With respect to the Router ID, this is the largest IP interface in a logical (loopback). If there is a logical interface, the RID is defined as the highest IP address of an interface participating in the process of routing.

You can download them below:

Laboratório Spanning Tree Protocol – ConvergênciaLab Spanning Tree Protocol – Convergence

Olá Pessoal,

Encontrei este laboratório na Internet, dedicado ao aprendizado de como funciona a convergência do protocolo STP (Spanning-Tree Protocol).

Com ele é possível ver quem é o Root Bridge, as Root, Designed e Non-designed ports e acompanhar a convergência da rede conforme se apagam links e Switchs da topologia.

Laboratório Frame-Relay COMPLETO!Frame-Relay Lab COMPLETE!

Olá Pessoal,

É com imenso prazer que estou publicando este laboratório completo, desenvolvido a contento incluindo os arquivos txt de configuração de cada um dos routers e switch Frame-Relay e o arquivo do Packet Tracer.

Prosseguindo.

Este laboratório é composto de uma matriz que provê internet para as outras filiais conectadas cada uma por um link ponto-a-ponto a esta, como apresentado na figura abaixo:

Os artefatos implementados neste laboratório:

  • Criação de nuvem Frame-Relay possibilitando um circuito virtual na camada de enlace.
  • Utiliza o protocolo EIGRP com redistribuição da rota default possibilitando uma comunicação completa de toda a malha.
  • Utiliza NAT com Overload (PAT) possibilitando o acesso a ‘Internet’.

Os seguintes artefatos poderiam ter sido implementados a mais para ilustrar um cenário mais real e organizacional:

  • Serviço DHCP na Matriz para prover aos hosts (PCs) IPs alocados dinâmicamente.
  • Serviço DNS na Matriz provendo tradução dos nomes.

Itens a desfrutar neste laboratório:

  • Como o Frame-relay encapsula os quadros (frames) e entender o papel da nuvem e os diversos componentes.
  • Verificar a aprendizagem de rotas do EIGRP através dos diversos comandos show disponíveis.
  • Verificar as adjacências utilizando o protocolo CDP (Cisco Discovery Protocol).
  • Verificar as configurações para cada um dos equipamentos (Switch Frame-Relay, Roteador na Matriz e Filiais).
  • Absorver os conceitos passados neste laboratório.
  • E não esqueça, a criatividade é o limite. Modifique, pergunte e deixe-me saber o que achou deste laboratório.

Pessoal, acredito que é isso. Espero que aproveitem o laboratório, pois eu estou.

Como meu objetivo é de obter o CCNA, este laboratório engloba diversos conceitos interessantes num case aproximado do mundo real.

Um abração,

Maurício.Hello Guys,

It is with great pleasure that I am posting this complete lab, developed to the satisfaction txt files including the configuration of each router and switch, Frame Relay and Packet Tracer file.

Continuing.

This laboratory consists of a matrix that provides internet to the other branches each connected by a link point-to-point to this, as in figure below:

The artifacts implemented in this laboratory:

  • Creating Frame-Relay cloud allowing a virtual circuit in the link layer.
  • Uses the protocol to EIGRP redistribution of enabling a default route complete communication throughout the mesh.
  • Used with NAT Overload (PAT) allowing access to ‘Internet’.

The following artifacts could have been implemented to further illustrate a more realistic scenario and organizational:

  • DHCP service to provide to the matrix hosts (PCs) assigned IPs dynamically.
  • DNS service in the matrix providing translation of names.

Items to enjoy in this laboratory:

  • How the Frame-relay encapsulates the frames (frames) and understand the role of cloud and the various components.
  • Check the learning of the EIGRP routes through the various show commands available.
  • Check the surroundings using the protocol CDP (Cisco Discovery Protocol).
  • Check the settings for each of the equipment (Switch, Frame Relay, Routing Matrix and the Subsidiaries).
  • Absorb the concepts after this lab.
  • And do not forget, creativity is the limit. Modify, ask and let me know what you think of this laboratory.

I personally believe that is. I hope you enjoy the lab, because I am.

As my goal is to get the CCNA, this lab includes various interesting concepts in a case about the real world.

A Abrasive,

Maurício.

Laboratório VLAN TrunkingLab VLAN Trunking

Olá Pessoal,
Fiz um laboratório de switching um tanto básico, mas bem interessante para identificar a diferença entre links de acesso (switchport mode access) entre VLANs e ‘entroncamentos’ ou trunking (switchport mode trunk). Abaixo, segue a topologia inicial baseada nos switches Cisco Catalyst 2950.

Topologia inicial do Laboratorio Trunking
Topologia inicial do Laboratorio Trunking

Este Lab mostra a diferença entre utilizar 3 links de acesso para passar dados de 3 VLANS entre diferentes switches e utilizar apenas uma porta trunk para isso. O Lab poderia ser mais elaborado para depois se colocar EtherChannels e compartilhar a banda destes 3 links, mas o que possui já é interessante.

Este Lab foi extraído de um ‘pacotão’ com diversos laboratórios: Link

Segue o link para a atividade descrita contendo as resoluções escritas e do Packettracer:  VLAN Trunking Lab

Adicionado Roteamento entre Vlans e VTP. Vlan Trunking + VTP + Roteamento entre VLans Lab

Abraços,

E sucesso.

Maurício.Hello Guys,
I made a laboratory of switching a bit basic, but very interesting to identify the difference between links of access (switchport mode access) between VLANs and ‘junctions’ or trunking (switchport mode trunk). Below, follows the initial topology based switchesCisco Catalyst 2950.

This lab shows the difference between using 3 links for access to move data between different VLANs, 3 switches and use only atrunk port for that. The Lab could be more prepared to put EtherChannels and then share the bandwidth of these 3 links, but what has is interesting.

This Lab was extracted from a ‘package’ with different laboratories: Link

Frame-Relay Lab.

Olá Pessoal,

Iniciando nossa proposta de estudos estou postando um laborátório interessante de Frame-Relay utilizando a topologia de matriz e filiais, com a nuvem Frame-relay em nosso controle.

Abaixo segue as instruções:

Objetivo:

Aprimorar os conhecimentos nas diversas áreas de configuração, implementação, solução de problemas manipulação dos comandos debug e show nos Routers e Switches. Este laboratório deverá conter configuração para as diversas áreas de estudo apresentadas abaixo:
O endereçamento IP será feito com base na rede 172.16.0.0/24 (classe B -> C). Cada filial necessita de 120 endereços para hosts, e na matriz 600. Para os links PPP uma sub-rede /30. Já no multi-point utilizar qualquer outro, respeitando o limite de classe.
Para a configuração com NAT utilize a classe 200.234.1.0/28.

A topologia utilizada é a seguinte:

Topologia Lab Frame-relay
Topologia Lab Frame-relay

Tabela IP:
Como temos a sub-rede disponível 172.16.0.0 / 16 ou 255.255.0.0 (máscara padrão) vamos alterar esta máscara para /24 ou 255.255.255.0. Ao fazer isto, sabemos que para cada sub-rede temos 254 ips válidos, ou 2^8(à potência de) = 256 – 2(nº de rede e broadcast) = 254 IPS validos. Como precisamos de 600, 120, 120 e 120, além dos links de wan ppp.
