ParticipanteQuais modelos são eles? na foto não da para ver e não tem descrição deles… estou querendo montar meu lab.. se for os que desejo compro os 3. no aguardo..
ParticipanteEstou na espera do link e poder participar do leilão…
Participante@JaymeVerg
Assim que concluir vou explicar sim blz, até porque vai me ajudar tenho prova da pós sobre o assunto ai já estudo e vejo como estão meus conceitos.
Quanto aos desafios vou deixara qui anotado as referências mas vou tentar blz.
Participante@Leandro Freitas
Vou sim, demorei porque estava almoçando hehehe começar agora.
Participante@Leandro Freitas
não entendi o OSPF já está rodando no backbone MPLS ? ou você está falando das configurações dos DRs e BDRs ?
Participante@Leandro Freitas
Pingou a VPNa (CE11) pingou na VPNa(CE21) tudo blz agora eu fui olhar meu show run da CEs tava com uma rota doida isso só depois do tracert ter se perdido da nerial de entrada para a CEs
vlw pela ajuda.
Vlw pela ajuda, eu estava procurando no site da blindhog mas não encontrei nada, mais valeu vou dar uma estudada no webnar.
Participante@Leandro Freitas
nos CEs tem rota default para o PE1, deve estar faltando algum cabelo de sapo hehehe estou catando aqui no google para ver o que é.

rotas adicionadas e propagadas pelo bgp conforme mostrada abaixo;

Mesmo assim nada de ping entre os CE11 e CE21.
@Jayme
estou dando uma pesquisada sobre o VRF-Lite para ver o que está faltando nas configurações aqui..

Estou com uma dúvida quanto a tabela de roteamento da vrf vpna, não era para constar a rede do outro clinet da vrf vpna ? a meu ver era para ela vim por bgp já que ele propaga rota estática??

Todos os router do Backbone se comunicam sejam pelo ip da serial ou pelo das loopback. O ospf está montando a tabela de vizinhaça e os loopback está sendo aprendidos conforme segue abaixo.

como segue no ínicio do post o show runnin do PE1 com uma rota estática de vrf o bgp não era para propagar ela ?
Participantergentil,
hehe antes de postar dei uma lida no post dele.
ParticipanteFlyner,
Obrigado, o CBT eu já tenho vou atras do Net Academy.
ParticipanteFlyner,
essa é minha ideia, porque antes de me inscrever na pós eu comprei os 2 livros da ICND deve estar chegando segunda-feira e estou revisando alguns assuntos linux e fazendo alguns labs e pretendo tirar ccna e lpi CCNP só quando terminar a pós porque ai já vou ter visto todo assunto que cobre.
Participanteatualmente estou trabalhando como adminsitrador de redes Linux e Windows. e vou começar a pós como falei para entrar na área CISCO o que eu quero é manter os estudos CISCO + Linux isso em certificação porque trabalho com windows mais não sou certificado.
