This article walks through the configuration of Avi Vantage’s native IPAM solution, which is available for the following clouds:

• Containers (Mesos, OpenShift, Docker UCP, Rancher)
• Linux server cloud (bare metal)
• VMware
• No access

IPAM Configuration

Avi Vantage allocates IP addresses from a pool of IP addresses within the subnet configured as listed below.

1. Navigate to Infrastructure > Clouds, and click on the cloud name.
2. Select Network and click on Create.
3. Enter a name for the network.
4. Add networks for IP address allocation:
   1. Click on Add Subnet.
   2. Enter the subnet address, in the following format: 10.160.160.0/24
   3. Click on Add Static IP address pool. Avi Vantage will allocate IP addresses from this pool. For example, 10.160.160.100-10.160.160.200.
   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, i.e., Mesos, OpenShift, Docker UCP, and Rancher), create another network with the appropriate link-local subnet and a separate IPAM/DNS Profile.

North-south IPAM network creation after following steps above:

East-west IPAM network configuration:

IPAM networks are now created. Navigate to Templates > IPAM/DNS Profile and create a placeholder for IPAM (separate one for east-west wherever it’s relevant). You can assign one or more of the networks created above to be default usable networks if no specific network and/or subnet are provided in the virtual service configuration. The administrator can configure these networks, thus eliminating the need for developers to provide specific network/subnets while creating their applications.

VRF-aware IPAM

Starting with Avi Vantage 17.2.4, the IPAM/DNS profile editor includes a checkbox the setting of which causes Avi Vantage to only allocate IPs from networks in the virtual service’s VRF. This option is application to Avi Vantage IPAM only.
