      Active EIP 2

      EIP 2 used by the VPN gateway to communicate with the on-premises data center.

      2.2.2.2

  4. Configure a customer gateway.

    1. Choose Virtual Private Network > Enterprise – Customer Gateways, and click Create Customer Gateway.
    2. Set parameters as prompted.

      Table 2 describes the parameters for creating a customer gateway.

      Table 2 Parameters for creating a customer gateway

      1.1.1.1

      BGP ASN

      BGP AS number of the AR router.

      65000

  5. Configure VPN connections.

    In this scenario, a VPN connection is created between the AR router and each of the active EIP and active EIP 2 of the VPN gateway.
    1. Choose Virtual Private Network > Enterprise – VPN Connections, and click Create VPN Connection.
    1. Create VPN connection 1.

      Table 3 describes the parameters for creating a VPN connection.
