Configuration on the AR Router

Procedure

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

    <AR651>system-view

  3. Configure an IP address for the WAN interface.

    [AR651]interface GigabitEthernet 0/0/8

    [AR651-GigabitEthernet0/0/8]ip address 1.1.1.1 255.255.255.0

    [AR651-GigabitEthernet0/0/8]quit

  4. Configure a default route.

    [AR651]ip route-static 0.0.0.0 0.0.0.0 1.1.1.254

    In this command, 1.1.1.254 is the gateway address for the AR router's public IP address. Replace it with the actual gateway address.

  5. Configure routes to the active and standby EIPs of the VPN gateway.

    [AR651]ip route-static 1.1.1.2 255.255.255.255 1.1.1.254

    [AR651]ip route-static 2.2.2.2 255.255.255.255 1.1.1.254

    • 1.1.1.2 and 2.2.2.2 are the active and standby EIPs of the VPN gateway, respectively.
    • 1.1.1.254 is the gateway address for the AR router's public IP address.

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

    [AR651]IPsec authentication sha2 compatible enable

    [AR651-ike-peer-hwpeer2]ikev2 authentication sign-hash sha2-256

    [AR651-ike-peer-hwpeer2]quit

    The commands are described as follows:

    • ike peer hwpeer1 and ike peer hwpeer2: correspond to two VPN connections.
    • pre-shared-key cipher: specifies a pre-shared key.
    • local-address: specifies the public IP address of the AR router.
    • remote-address: specifies the active or standby EIP of the VPN gateway.

  10. Configure an IPsec profile.

    [AR651]IPsec profile hwpro1

    [AR651-IPsec-profile-hwpro1]ike-peer hwpeer1

    [AR651-IPsec-profile-hwpro1]proposal hwproposal1

  11. 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-Tunnel0/0/2]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 the standby EIP 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 or standby EIP of the VPN gateway.

  12. 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 the standby EIP 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.

  13. 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 192.168.1.0 255.255.255.0 Tunnel0/0/1 track nqa IPsec_nqa1 IPsec_nqa1

    [AR651]ip route-static 192.168.0.0 255.255.255.0 Tunnel0/0/2 preference 100 track nqa IPsec_nqa2 IPsec_nqa2

    [AR651]ip route-static 192.168.1.0 255.255.255.0 Tunnel0/0/2 preference 100 track nqa IPsec_nqa2 IPsec_nqa2

    The parameters are described as follows:

    • 192.168.0.0 and 192.168.1.0: indicate VPC subnets.
      • Association between the static route and NQA needs to be configured for each subnet.
      • Tunnelx and IPsec_nqax in the same command correspond to the same VPN connection.
    • preference 100 indicates the route preference. If this parameter is not specified, the default value 60 is used.

      In this example, the two VPN connections work in active/standby mode, and traffic is preferentially transmitted through the VPN connection to which the active EIP of the VPN gateway belongs.

      To load balance traffic between the two VPN connections, delete preference 100 from the preceding commands.
