DESAFIO EIGRP+ESTATICO+HSRP NIVEL 1

Este LAB possui um pouco de EIGRP, roteamento estático de HSRP.

Sua tarefa estara completa quando:

1 - o CE_P deve ser o principal no HSRP e no EIGRP (no momento é backup)

2 - o CE_P conseguir pingar o ip 20.0.0.1 da Fast 0/1 do C2

3 - o C2 conseguir pingar o IP virtual do HSRP 172.10.0.1

4 - O C2 conseguir pingar as Loopbacks do CE_P (10.0.0.4) e CE_B (10.0.0.3)

Topologia:

Falai pessoal do Fórum, blz.

Então acho que foi, estou disponibilizando abaixo as configurações e no final do tópico a solução, referente a este Desafio da Cisco BR.

Segue resposta do Desafio

1 - o CE_P deve ser o principal no HSRP e no EIGRP (no momento é backup)
R: Foi alterado onde o Hsrp(CE_P – Prioridade 130 e CE_B prioridade 125)
R1.1: CE_P#sh standby
FastEthernet0/0 - Group 1
State is Active

R: Para mudar o sentido do roteamento mudei o bandwidth nas interfaces, onde o EIGRP estará escolhendo a de bandwidth mais alto, conforme seu cálculos custo. Existe outra forma de ser feio com offset-list ` mas acho que não era o intuito deste desafio.

5: C1 também estava sem a configuração ip subnet-zero, foi adicionada.
6: Durante teste foi verificado que o EIGRP também estava divulgando o roteamento de para CE_P e CE_B através da LAN devido o custo das fast, onde foi adicionado a linha. passive-interface
7: Existia a rota estática 10.0.0.0/16 de C1 para C2 sendo divulgada o que poderia direcionar todos os encaminhamento das Loopbacks dos demais incorretamente para C2 devido o auto-summary(EM C1), rota foi alterada para 10.0.0.1/32.

Novamente valeu Nakano pelo Desafio.

Abraços a todos,
Marcelo Guerra.

Valeu Marcelo era isso mesmo, a idéia no EIGRP era só alterar o bandwitdh mesmo. Como neste caso não utilizamos QoS não há impacto.

Uma das pegadinhas que tinha colocado era o subnet-zero, que impedia a configuração da rota estatica.

A alteração da rota foi uma boa idéia, mas apenas desabilitar o auto-summary já teria resolvido.

Amanhã vou ver se monto um lab com BGP, RR e MPLS para ficar um pouco mais dificil.

parabéns, a madruga está te fazendo bem hein eheheheh
