Configurar o Roteador via TELNET

 

Primeiramente devemos mudar o IP da estação para a mesma rede da porta Ethernet/FastEthernet do roteador e que exista conexão física entre o Roteador e esta estação.

 

 

 

 

  • Copiar para um servidor TFTP ou de um Servidor TFTP para o roteador.

 

 


 

Primeiro abre o servidor TFTP em uma estação, depois usa o comando copy oque? tftp (onde oque? Pode ser a flash, NVRAM, RAM, etc...) informe o ip (223.8.151.3) deste servidor e o nome do Arquivo de BACKUP (leandro_router).

 

Lab_C#copy star tftp

Address or name of remote host []? 223.8.151.3

Destination filename [lab_c-confg]? leandro_router

!!

950 bytes copied in 2.340 secs (406 bytes/sec)

Para copiar do servidor TFTP use o comando copy tftp run , onde run pode ser substituído por qualquer tipo de memória do roteador.

·        As configurações da rota estáticas são administradas manualmente por um administrador de rede que a insere em uma configuração do roteador. O administrador deve atualizar manualmente essa entrada de rota estática sempre que uma atualização da alteração da topologia de internetwork for necessária. Para configuirar as rotas estáticas usamos o comando ip route Rede_Destino Mask Porta_de_Saída ou ip route Rede_Destino Mask IP_do_1º_Salto.
