3 Introduction Devstack is basically an opinionated script to create an OpenStack environment. It can also be used to demonstrate starting/running OpenStack services and provide examples of using them from a command line. Infoblox Devstack Plugin offers the following benefits: Automatic creation of DNS and DHCP Fixed Address records when new host instances are created. Automatic reclamation of IP addresses and DNS names from decommissioned instances. A single centralized view of all IPAM, DNS, and DHCP data for the DevStack environment, along with VMware, Microsoft, and other cloud and physical environments. Full visibility into IP Addresses, DNS, and DHCP record creation/deletion and DHCP lease history for auditing, compliance tracking and reporting. Ability to use Infoblox Grid Members to serve DNS and DHCP services to Virtual Machines in individual Devstack Tenants. Support for non-overlapping and overlapping IP address spaces, including fixed IP addresses in private and shared networks, and floating IP addresses in external/public networks. This deployment guide will walk you through configuring Devstack (Newton release) with Infoblox Plugin. Prerequisites This guide assumes that Devstack installation would be performed on a virtual infrastructure based on VMware vsphere 6.5. Port Group Creation in vcenter Server This deployment guide leverages Distributed virtual switch (DVS) for Devstack networking. 1. Login to the vsphere Web Client and go to the networking tab to access DVS 2. Right click on the DVS Distributed Port Group New Distributed Port Group 3. Enter a name for this port group and click on next Infoblox Inc. All rights reserved. Installing and Configuring Devstack Newton for Infoblox Integration Page 3 of 38

Deploying Grid Master 1. Login to the vsphere web client and deploy the NIOS ova file. 2. Ensure that it is connected to the previously created DVS port group. 3. Power on NIOS and apply the following licenses a. NIOS b. DNSone with Grid (DNS, DHCP, Grid) c. Cloud Network Automation license. 4. Once licenses are configured, NIOS networking needs to be configured. 5. After configuring the networking, log in to the Grid using a browser on the Windows VM Infoblox Inc. All rights reserved.

For example, if you are planning to create 2 tenants in Devstack, you must have 2 members added to the grid master. 1.

7 6. Configure this NIOS instance as grid master 7. Change the Host Name to nios.infoblox.com and leave the other options as default. Deploying Grid Members Note: You can only have as many tenants as the number of grid members you have. For example, if you are planning to create 2 tenants in Devstack, you must have 2 members added to the grid master. 1. Go to the Grid Members Add and then enter the details of Grid members which you will be adding. 2. Login to the vsphere web client and deploy 2 NIOS as members 3. Apply NIOS and DNSone with Grid (DNS, DHCP, Grid) licenses to both the members. 4. Configure the networking for both members and add them to the Infoblox Grid Infoblox Inc. All rights reserved.

pfsense pfsense is an open source firewall/router computer distribution based on FreeBSD. It can be installed on a physical computer or a virtual machine.

9 pfsense pfsense is an open source firewall/router computer distribution based on FreeBSD. It can be installed on a physical computer or a virtual machine. This deployment guide uses pfsense for NATing. It is configured with two network interfaces: eth0 and eth1 eth0 is connected to the external network. eth1 is connected to the internal network. This acts like a gateway for the internal network to access external network. To create and configure pfsense 1. Create a VM with 2 vcpu and 1GB ram and attach the pfsense iso to it. 2. Add a second network card and select the network (previously created Distributed port Group) 3. Power on the pfsense VM Infoblox Inc. All rights reserved.
