Desafio 1 – V-LANs, VTP, VLSM e EtherChannel
Olá pessoal, tenho andado muito ocupado com trabalho e faculdade, por isso andei meio sumido, mais como meu curso acabou resolvi fazer este post com uma topologia para configurarmos.
O desafio consiste no seguinte:
Endereçamento dos hosts para as V-lans indicadas.
Rede: 172.16.22.0/20
Vlans:
122 – Alunos – 150 hosts
222 – ADM – 80 hosts
322 – LAB – 12 hosts
422 – Biblio – 30 hosts
1 – default
Configurar dominio VTP conforme indicado.
Dominio VTP: UNIFEB, senha: cisco
Os switches indicados deverão ser configurados como
Server e os demais como Client
Configurar os etherchannels indicados
A partir de qualquer computador deverá ser
possivel acessar os switches para realizar
configurações.
É isso ai pessoal, o desafio está lançado, dia 11/12 postarei os Confs de cada Switch e o Roteador.
Podem postar seus confs deixando nos comentários deste post.
Segue o arquivo .PKT sem configurações para que não precisem montar a topologia do zero

É isso ai pessoal, bons estudos!!!!

Resolução:
1º Passo: Nomear cada elemento da nossa topologia conforme a figura
Ex: SW1, SW2, H1, H2, R1, NT1, NT2, etc…
2º Passo: Endereçamento (VLSM)
################# Endereçamento dos hosts para as V-lans indicadas #################
Rede com máscara /20 ( intervalo 16 sub-redes com 4094 Hosts )
172.16.22.0/20 – 172.16.37.255/20
Como não precisaremos de tantos hosts assim, faremos adivisão conforme exemplificado abaixo
VLAN 122 – Alunos 150 hosts 172.16.22.0/24 – 0 a 256
VLAN 222 – ADM 80 hosts 172.16.23.0/25 – 0 a 128
VLAN 422 – BIBLIO 30 hosts 172.16.23.128/27 – 128 a 160
VLAN 322 – LAB 12 hosts 172.16.23.160/28 – 160 a 176
VLAN 1 – DEFAULT 13 hosts 172.16.23.176/28 – 176 a 192
Para atender nosso exercicio precisaremos apenas das redes 172.16.22.XX/XX e 172.16.23.XX/XX
3º Passo:
################# Configurando IP’s da VLAN Default em todos os Switchs e no Router #################
OBS: Gateway de cada v-lan iremos setar o ultimo IP válido de cada SUB-REDE na configuração do Roteador
###### Para a segurança dos dispositivos habilitaremos usuario e senha para TELNET e SSH ############

PASSO 11:
Faça todos os testes de ping ou outros protocolos pelo modo de simulação do Packet Tracer
Se você fez todas as configurações corretamente nesse momento todos os HOSTS devem se comunicar.

O Packet Tracer não consegue concluir a convergência quando ativado o Etherchannel nestas interfaces, e não consegui descobrir o problema, se alguem tiver uma ideia, poderia postar aqui.
Obrigado e até o proximo desafio!!!!
Fala aí Diogo blz!
Eu iniciei o curso CCNA pela Fundação Bradesco, e terminei o módulo 1 essa semana.
Estou esperando você postar as respostas desse desafio, pois as topologias que eu montei até presente momento foram simples, essa que você passou me parece um pouco complexa, pois ainda não estudei os protocolos VTP,LACP,PAGP, obrigado pela atenção um abraço.
Coincidência Rui, acabei de postar a resolução…. abraço e bons estudos, qualquer dúvida pode perguntar….
Diogo, baixei o lab porém qdo vou abrir meu pkt. diz que esse arquivo não é compatível com essa versão, uso o pkt. 5.3, poderia postar novamente o lab. obrigado.
