Os comandos são descritos da seguinte forma:

• pre-shared-key cipher: configura uma PSK, que deve ser a mesma configurada no console da VPN.
• local-address: especifica o endereço IP público do roteador AR.
• remote-address: especifica o EIP ativo ou em espera do gateway de VPN.

[AR651-Tunnel0/0/2]quit

Os comandos são descritos da seguinte forma:

• interface Tunnel0/0/1 e interface Tunnel0/0/2: indicam as interfaces de túnel correspondentes às duas conexões de VPN.

  Neste exemplo, Tunnel0/0/1 estabelece uma conexão de VPN com o EIP ativo do gateway de VPN, e Tunnel0/0/2 estabelece uma conexão de VPN com o EIP em espera do gateway de VPN.

• ip address: configura um endereço IP para uma interface de túnel no roteador AR.
• source: especifica o endereço IP público do roteador AR.
• destination: especifica o EIP ativo ou em espera do gateway de VPN.

[AR651-nqa-IPsec_nqa2-IPsec_nqa2]quit

Os comandos são descritos da seguinte forma:

• nqa test-instance IPsec_nqa1 IPsec_nqa1 e nqa test-instance IPsec_nqa2 IPsec_nqa2: configure duas instâncias de teste de NQA chamadas IPsec_nqa1 e IPsec_nqa2.

  Neste exemplo, a instância de teste IPsec_nqa1 é criada para a conexão de VPN à qual o EIP ativo do gateway de VPN pertence; a instância de teste IPsec_nqa2 é criada para a conexão de VPN à qual pertence o EIP em espera do gateway de VPN.

• destination-address: especifica o endereço da interface do túnel do gateway de VPN.
• source-address: especifica o endereço da interface de túnel do roteador AR.

[AR651]ip route-static 192.168.0.0 255.255.255.0 Tunnel0/0/2 track nqa IPsec_nqa2 IPsec_nqa2

Os parâmetros são descritos como segue:

• 192.168.0.0 indica a sub-rede local da VPC.
• Tunnelx e IPsec_nqax no mesmo comando correspondem à mesma conexão de VPN.
