Pacotão de Laboratórios Passo-a-passo para CCNAPackage of Step-by-step Labs for CCNA

Olá Pessoal,

Ao longo de meus estudos para a Certificação CCNA, tive muitas facilidades em relação à parte prática. Como fiz o curso Cisco Netacad de 2002 até 2004 com professores muito bons pude praticar bastante todo tipo de configuração, troubleshooting e muito mais. Tudo isso com dispositivos reais.

O que vejo em alguns roteiros de estudos de pessoas que estudam por contra própria é certa carência de prática no período intermediário de estudo. Ao meu ver, isso acontece devido à dificuldade em montar cenários e criar configurações do zero.

Neste post, quero disponibilizar a todos um ‘pacotão’ de laboratórios para o Packet Tracer que aborda diversos conceitos por meio de topologias variadas. Mas, o melhor de tudo é que o laboratório já lhe guia através de seus objetivos de configuração e/ou troubleshooting. Quando você finalizar a configuração clique em Check Results para verificar a score e obter um feedback de sua configuração.

Abaixo é apresentada a tela da topologia e de objetivo.
Pacotão de Laboratórios - Tela de Objetivos

Este pacotão possui diversos laboratórios, mas os que foram utilizado por mim estão disponíveis no primeiro link, da pasta PT3.2Saves. No segundo link, estão disponíveis outros laboratórios. Alguns, além de possuir o arquivo base contêm as respostas feitas por mim.

O arquivo que possui todo o passo-a-passo a ser aberto é o que possui a extensão PKA.

Seguem os links para download:

Qualquer dúvida entre em contato.

Um grande abraço e sucesso a todos!

Maurício Bentow Ghem.Hello Guys,

Throughout my studies for the CCNA certification, I had many facilities for the practical part. How did the current Cisco Netacad 2002 to 2004 with very good teachers could do much any kind of configuration, troubleshooting and more. All with actual devices.

What I see in some studies of routes for people to study by itself is a lack of practice in the intermediate period of study. In my view, this happens because of the difficulty in setting up scenarios and create from scratch.

In this post, I offer you a ‘package’ laboratories to the Packet Tracer which addresses various concepts by means of various topologies. But best of all is that the laboratory has already guide their goals through the configuration and / or troubleshooting.When you finish setting click Check Results to see the score and get a feedback from your configuration.

Below is the screen of the topology and order.

Pacotão de Laboratórios - Tela de Objetivos

This package has several laboratories, but those used by me are available on the first link, the folder PT3.2Saves. In the second link, other laboratories are available. Some, besides having the basic file containing the answers made by me.

The file that has all the step by step to open is what is the extent PKA.

Any questions please contact us.

A big hug and success to all!

Informações como: endereço IP, área OSPF, Router ID, tipo de rede (ppp,point-to-multipoint), informações sobre DR/BDR(para links ppp o OSPF não elege DRs), timers e informações sobre vizinhos (adjacências).
Show ip ospf neighbor OSPF Apresenta um resumo e status da adjacência com os vizinhos. Este comando apresenta informações como: ID do router vizinho, estado (DR,BDR..), dead time (tempo até a rota se extinguir, ou receber um novo hello), endereço IP do vizinho e interface local do Router no qual se encontra este vizinho.
Show ip nat translations NAT Apresenta as traduções NAT feitas e informações como: protocolo, inside local e global e outside local e global.

Based on this laboratory for Frame-relay, I continue the list of commands Show. Now, trying to: routing, OSPF, NAT, and ACL.

Below shows a picture of the topology, and then show the commands based on it.

Topologia do Laboratório Completo de Frame-Relay.

Topology of the Laboratory of Full-Frame Relay.

COMMAND A RELATED RESULT
Show ip route Routing Table Displays the routing table. Shows the network in what was learned (dynamic or static) [administrative distance / metric] and IP and the interface on which this route was learned
Show ip protocols Routing Protocol Displays information from routing protocols running (summary and status). Information is given as specific details of each protocol (eg Router ID for OSPF), and advertising networks that are neighbors (source) routing.
Show ip ospf OSPF Displays the settings set to the OSPF protocol. Displays information such as: Router ID (the highest ID (IP) or the ID defined in the Loopback interface, if any) and timers.
show ip ospf data OSPF Displays now link the IDs, or the ID for each link (interface) has the time in which it was learned (age) and the link ID (ID of the interface of the router) that is advertising the route.
Show ip ospf interface <interface> OSPF Displays all information on each OSPF interface. Information such as IP address, OSPF area, Router ID, type of network (ppp, point-to-multipoint), information on DR / BDR (ppp links to the OSPF not elect DRs), timers and information about neighbors (vicinity).
Show ip ospf neighbor OSPF Presents a summary and status of the adjacency with its neighbors.This command displays information such as neighbor router ID, state (DR, BDR ..), dead time (time until the route goes out, or receives a newhello), IP address of the neighbor and the local router interface which is this neighbor.
Show ip nat translations NAT Displays NAT translations made and information such as protocol,inside global, outside local, and local and global.
Show ip Nat statistics NAT Displays statistics for NAT translation.
Show ip access-lists ACLs Displays IP ACLs all created and the number of matches (how many times it was applied).
