Step 5: Configuring the Customer Gateway Device

Procedure

In this example, the customer gateway device is an AR router of Huawei. For more examples of configuring customer gateway devices, see Administrator Guide.

  1. Log in to the AR router.
  2. Enter the system view. 

    <AR651>system-view

  3. Configure an IP address for the WAN interface. In this example, the WAN interface of the AR router is GigabitEthernet 0/0/8. 

    [AR651]interface GigabitEthernet 0/0/8
[AR651-GigabitEthernet0/0/8]ip address 22.xx.xx.22 255.255.255.0
[AR651-GigabitEthernet0/0/8]quit

  4. Configure a default route. 

    [AR651]ip route-static 0.0.0.0 0.0.0.0 22.xx.xx.1

    In this command, 22.xx.xx.1 is the gateway address of the AR router's public IP address. Replace it with the actual gateway address.

  5. Enable the SHA-2 algorithm to be compatible with the standard RFC algorithms. 

    [AR651]IPsec authentication sha2 compatible enable

  6. Configure an IPsec proposal. 

    [AR651]IPsec proposal hwproposal1
[AR651-IPsec-proposal-hwproposal1]esp authentication-algorithm sha2-256
[AR651-IPsec-proposal-hwproposal1]esp encryption-algorithm aes-128
[AR651-IPsec-proposal-hwproposal1]quit

  7. Configure an IKE proposal. 

    [AR651]ike proposal 2
[AR651-ike-proposal-2]encryption-algorithm aes-128
[AR651-ike-proposal-2]dh group14
[AR651-ike-proposal-2]authentication-algorithm sha2-256
[AR651-ike-proposal-2]authentication-method pre-share
[AR651-ike-proposal-2]integrity-algorithm hmac-sha2-256
[AR651-ike-proposal-2]prf hmac-sha2-256
[AR651-ike-proposal-2]quit

  8. Configure IKE peers. 

    [AR651]ike peer hwpeer1
[AR651-ike-peer-hwpeer1]undo version 1
[AR651-ike-peer-hwpeer1]pre-shared-key cipher Test@123
[AR651-ike-peer-hwpeer1]ike-proposal 2
[AR651-ike-peer-hwpeer1]local-address 22.xx.xx.22
[AR651-ike-peer-hwpeer1]remote-address 11.xx.xx.11
[AR651-ike-peer-hwpeer1]rsa encryption-padding oaep
[AR651-ike-peer-hwpeer1]rsa signature-padding pss
[AR651-ike-peer-hwpeer1]ikev2 authentication sign-hash sha2-256
[AR651-ike-peer-hwpeer1]quit
[AR651]ike peer hwpeer2
[AR651-ike-peer-hwpeer2]undo version 1
[AR651-ike-peer-hwpeer2]pre-shared-key cipher Test@123
[AR651-ike-peer-hwpeer2]ike-proposal 2
[AR651-ike-peer-hwpeer2]local-address 22.xx.xx.22
[AR651-ike-peer-hwpeer2]remote-address 11.xx.xx.12
[AR651-ike-peer-hwpeer2]rsa encryption-padding oaep
[AR651-ike-peer-hwpeer2]rsa signature-padding pss
[AR651-ike-peer-hwpeer2]ikev2 authentication sign-hash sha2-256
[AR651-ike-peer-hwpeer2]quit

    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.

  9. Configure an IPsec profile. 

    [AR651]IPsec profile hwpro1
[AR651-IPsec-profile-hwpro1]ike-peer hwpeer1
[AR651-IPsec-profile-hwpro1]proposal hwproposal1
[AR651-IPsec-profile-hwpro1]pfs dh-group14
[AR651-IPsec-profile-hwpro1]quit
[AR651]IPsec profile hwpro2
[AR651-IPsec-profile-hwpro2]ike-peer hwpeer2
[AR651-IPsec-profile-hwpro2]proposal hwproposal1
[AR651-IPsec-profile-hwpro2]pfs dh-group14
[AR651-IPsec-profile-hwpro2]quit

  10. Configure virtual tunnel interfaces. 

    [AR651]interface Tunnel0/0/1
[AR651-Tunnel0/0/1]mtu 1400
[AR651-Tunnel0/0/1]ip address 169.254.70.1 255.255.255.252
[AR651-Tunnel0/0/1]tunnel-protocol IPsec
[AR651-Tunnel0/0/1]source 22.xx.xx.22
[AR651-Tunnel0/0/1]destination 11.xx.xx.11
[AR651-Tunnel0/0/1]IPsec profile hwpro1
[AR651-Tunnel0/0/1]quit
[AR651]interface Tunnel0/0/2
[AR651-Tunnel0/0/2]mtu 1400
[AR651-Tunnel0/0/2]ip address 169.254.71.1 255.255.255.252
[AR651-Tunnel0/0/2]tunnel-protocol IPsec
[AR651-Tunnel0/0/2]source 22.xx.xx.22
[AR651-Tunnel0/0/2]destination 11.xx.xx.12
[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.

  11. Configure NQA. 

    [AR651]nqa test-instance IPsec_nqa1 IPsec_nqa1
[AR651-nqa-IPsec_nqa1-IPsec_nqa1]test-type icmp
[AR651-nqa-IPsec_nqa1-IPsec_nqa1]destination-address ipv4 169.254.70.2
[AR651-nqa-IPsec_nqa1-IPsec_nqa1]source-address ipv4 169.254.70.1
[AR651-nqa-IPsec_nqa1-IPsec_nqa1]frequency 15
[AR651-nqa-IPsec_nqa1-IPsec_nqa1]ttl 255
[AR651-nqa-IPsec_nqa1-IPsec_nqa1]start now
[AR651-nqa-IPsec_nqa1-IPsec_nqa1]quit
[AR651]nqa test-instance IPsec_nqa2 IPsec_nqa2
[AR651-nqa-IPsec_nqa2-IPsec_nqa2]test-type icmp
[AR651-nqa-IPsec_nqa2-IPsec_nqa2]destination-address ipv4 169.254.71.2
[AR651-nqa-IPsec_nqa2-IPsec_nqa2]source-address ipv4 169.254.71.1
[AR651-nqa-IPsec_nqa2-IPsec_nqa2]frequency 15
[AR651-nqa-IPsec_nqa2-IPsec_nqa2]ttl 255
[AR651-nqa-IPsec_nqa2-IPsec_nqa2]start now
[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.

  12. Configure association between the static route and NQA. 

    [AR651]ip route-static 192.168.0.0 255.255.255.0 Tunnel0/0/1 track nqa IPsec_nqa1 IPsec_nqa1
[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.

Verification

  1. Log in to the management console.
  2. Click in the upper left corner of the page, and choose Networking > Virtual Private Network.
  3. In the navigation pane on the left, choose Virtual Private Network > Enterprise – VPN Connections.

    Verify that the states of the two VPN connections are both Normal.
