Exemplo: Alta disponibilidade stateful entre chassis de serviços de próxima geração para NAT e Firewall com estado
Este exemplo mostra como configurar a alta disponibilidade entre chassis de serviços de próxima geração para firewall stateful e serviços NAT.
Visão geral
Dois roteadores são configurados de forma idêntica para facilitar o failover stateful para serviços de firewall e NAT em caso de falha do chassi.
Configuração
Para configurar a alta disponibilidade entre chassis para este exemplo, execute estas tarefas:
- Configuração rápida da CLI
- Configuração de interfaces para chassi 1.
- Configurar informações de roteamento para o chassi 1
- Configuração de NAT e Firewall com estado para o Chassi 1
- Configurando o conjunto de serviços
- Configuração de interfaces para o chassi 2
- Configurar informações de roteamento para o chassi 2
Configuração rápida da CLI
Para configurar rapidamente este exemplo nos roteadores, copie os comandos a seguir e cole-os na janela do terminal do roteador depois de remover as quebras de linha e substituir as informações de interface específicas do seu site.
A configuração a seguir é para o chassi 1.
