The environment may be pure OpenStack option or Open Daylight L2-only option. +The deployment model may be HA or non-HA. The infrastructure may be bare metal or virtual environment. + +For complete instructions and documentations of setting up service VM as an IPv6 vRouter using ANY method, +please refer to: + +1.

IPv6 User Guide (HTML): http://artifacts.opnfv.org/ipv6/docs/gapanalysis/index.html + +**************************** +Pre-configuration Activities +**************************** + +The configuration will work in 2 environments: + +1. OpenStack-only environment +2. OpenStack with Open Daylight L2-only environment + +Depending on which installer will be used to deploy OPNFV, each environment may be deployed +on bare metal or virtualized infrastructure. Each deployment may be HA or non-HA. + +Refer to the previous installer configuration chapters, installations guide and release notes. + +****************************************** +Setup Manual in OpenStack-Only Environment +****************************************** + +If you intend to set up a service VM as an IPv6 vRouter in OpenStack-only environment of +OPNFV Colorado Release, please **NOTE** that: + +* Because the anti-spoofing rules of Security Group feature in OpenStack prevents + a VM from forwarding packets, we need to disable Security Group feature in the + OpenStack-only environment. +* The hostnames, IP addresses, and username are for exemplary purpose in instructions. + Please change as needed to fit your environment. +* The instructions apply to both deployment model of single controller node and + HA (High Availability) deployment model where multiple controller nodes are used. + +----------------------------- +Install OPNFV and Preparation +----------------------------- + +**OPNFV-NATIVE-INSTALL-1**: To install OpenStack-only environment of OPNFV Colorado Release: + +**Apex Installer**: + +.. code-block:: bash + + # HA, Virtual deployment in OpenStack-only environment + ./opnfv-deploy -v -d /etc/opnfv-apex/os-nosdn-nofeature-ha.yaml \ + -n /etc/opnfv-apex/network_setting.yaml + + # HA, Bare Metal deployment in OpenStack-only environment + ./opnfv-deploy -d /etc/opnfv-apex/os-nosdn-nofeature-ha.yaml \ + -i <inventory file> -n /etc/opnfv-apex/network_setting.yaml + + # Non-HA, Virtual deployment in OpenStack-only environment + ./opnfv-deploy -v -d /etc/opnfv-apex/os-nosdn-nofeature-noha.yaml \ + -n /etc/opnfv-apex/network_setting.yaml + + # Non-HA, Bare Metal deployment in OpenStack-only environment + ./opnfv-deploy -d /etc/opnfv-apex/os-nosdn-nofeature-noha.yaml \ + -i <inventory file> -n /etc/opnfv-apex/network_setting.yaml + + # Note: + # + # 1.
