4.1. Infrastructure Setup

In order to set up the service VM as an IPv6 vRouter, we need to prepare 3 hosts, each of which has minimum 8GB RAM and 40GB storage. One host is used as OpenStack Controller Node. The second host is used as Open Daylight Controller Node. And the third one is used as OpenStack Compute Node.

Please NOTE that Although the deployment model of single controller node is assumed, in case of HA (High Availability) deployment model where multiple controller nodes are used, there is no impact and the setup procedure is the same.

For exemplary purpose, we assume:

  • The hostname of OpenStack Controller+Network+Compute Node is opnfv-os-controller, and the host IP address is 192.168.0.10
  • The hostname of OpenStack Compute Node is opnfv-os-compute, and the host IP address is 192.168.0.20
  • The hostname of Open Daylight Controller Node is opnfv-odl-controller, and the host IP address is 192.168.0.30
  • We use opnfv as username to login.
  • We use devstack to install OpenStack Kilo. Please note that OpenStack Liberty can be used as well.

The underlay network topology of those 3 hosts are shown as follows in Fig. 4.1:

Please note that the IP address shown in Fig. 4.1 are for exemplary purpose. You need to configure your public IP address connecting to Internet according to your actual network infrastructure. And you need to make sure the private IP address are not conflicting with other subnets.
