This section explains the steps to configure IPAM.

Prerequisites

Avi Load Balancer allocates IP addresses from a pool of IP addresses within the subnet configured listed as follows.

Procedure

  1. Navigate to Infrastructure > Cloud Resources > Networks, select the cloud and click CREATE.
  2. Specify a name for the network.
  3. Under IP Address Management, select the Enable DHCP and Enable IPv6 Auto Configuration options as required.
  4. Add IPv4, IPv6 networks for IP address allocation:
    1. Click ADD under Subnets.
    2. Enter the Subnet Prefix.
    3. Specify the range of the pool under IP Address Pool. Avi Load Balancer will allocate IP addresses from this pool. For example, 9.9.9.100-9.9.9.200.
    4. Click SAVE.
    5. Repeat 1-4 for each network to be used for IP address allocation.
  5. Click SAVE.
    Note:

    • Virtual service creation will fail if the static IP address pool is empty or exhausted.

    • For East West IPAM (applicable to container-based clouds, such as, Mesos, OpenShift, Kubernetes, Docker UCP, and Rancher), create another network with the appropriate link-local subnet and a separate IPAM/ DNS Profile.

    Usable Networks

    This feature enables assigning one or more of the networks created above to be default usable networks, if no specific network/ subnet is provided in the virtual service configuration. An administrator can configure these networks, thus eliminating the need for a developer to provide a specific network/ subnet while creating a virtual service for the application.
