The commands are described as follows:

• pre-shared-key cipher: configures a PSK, which must be the same as that configured on the VPN console.
• local-address: specifies the public IP address of the AR router.
• remote-address: specifies the active EIP or active EIP 2 of the VPN gateway.

[AR651-Tunnel0/0/2]IPsec profile hwpro2

[AR651-Tunnel0/0/2]quit

The commands are described as follows:

• interface Tunnel0/0/1 and interface Tunnel0/0/2: indicate the tunnel interfaces corresponding to the two VPN connections.

  In this example, Tunnel0/0/1 establishes a VPN connection with the active EIP of the VPN gateway, and Tunnel0/0/2 establishes a VPN connection with active EIP 2 of the VPN gateway.

• ip address: configures an IP address for a tunnel interface on the AR router.
• source: specifies the public IP address of the AR router.
• destination: specifies the active EIP or active EIP 2 of the VPN gateway.

[AR651-nqa-IPsec_nqa2-IPsec_nqa2]quit

The commands are described as follows:

• nqa test-instance IPsec_nqa1 IPsec_nqa1 and nqa test-instance IPsec_nqa2 IPsec_nqa2: configure two NQA test instances named IPsec_nqa1 and IPsec_nqa2.

  In this example, the test instance IPsec_nqa1 is created for the VPN connection to which the active EIP of the VPN gateway belongs; the test instance IPsec_nqa2 is created for the VPN connection to which active EIP 2 of the VPN gateway belongs.

• destination-address: specifies the tunnel interface address of the VPN gateway.
• source-address: specifies the tunnel interface address of the AR router.

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

The parameters are described as follows:

• 192.168.0.0 indicates the local subnet of the VPC.
• Tunnelx and IPsec_nqax in the same command correspond to the same VPN connection.
