Date and Time: PDT 8:00am / UTC 15:00, Friday October 16, 2015
Chair: Bin Hu (AT&T)
Participants:

We focused on discussing current steps and instructions of setting up Service VM as IPv6 vRouter in native OpenStack environment (with ML2 OVS) and in OpenStack+ODL environment. In summary:

Current setup is based on environment of OS+ODL. This is documented in wiki.
- There are many gaps in ODL Lithium SR1, such as:
  - ODL-L3 doesn't support IPv6
  - ODL doesn't support Shared Tenant Networks
  - Security groups for IPv6 is not supported
  - net-virt provider doesn't support IPv6. This prevents us from using Neutron REST API to create subnets because exceptions are thrown.
    - There will be a workaround in SR2 to avoid Java exception. But full feature support will be in later ODL releases.
- Thus the role of ODL is to provide L2 connectivity. No other features of ODL can be used in case of IPv6.
  - In this case, we still need to use neutron-l3-agent for IPv6 router namespace, and other Neutron features as well when needed
  - When OpenStack is upgraded to Liberty, one additional benefit in IPv6 is its Prefix Delegation support in Neutron.
  - However, PD doesn't add significant value to our IPv6 PoC
  - Thus upgrading OpenStack to Liberty is the same as using Kilo effectively
- When ODL gets perfect and fully supports IPv6, we will use ODL-L3 instead of neutron-l3-agent.
  - Neutron becomes pass-through agent effectively
  - Thus the version of OpenStack doesn't make any difference
- We need to install ODL Lithium SR2 to very several bug fixes in order to be able to use Neutron REST APIs to create subnets.
  - Sridhar will work on this

Previously, we experimented the setup in native OS environment with ML2 OVS. This is also documented in wiki.\
- Sridhar will verify the documentation, and revise it accordingly.

For B Release deliverables, we assume that installer will take care of Step 1 through 3 to create OS+ODL environment. We only need to provide Step 4 and Step 5 documentation and instruction for B release.
- One issue is that our current setting is to use neutron-l3-agent instead of odl-l3. We need to verify the end state after installation, i.e. neutron-l3-agent disabled or not, odl-l3 enabled or not.
  - We may need additional instructions before Step 4, and after installation.
- Bin will communicate with Tim and Jonas to confirm the end state.

We talked about future roadmap including:
- Phase 2: more environments with other SDN controllers, such as OpenContrail, ONOS, Midonet, etc.
- Phase 3: full-blown, bare metal environment
- Both Phase 2 and Phase 3 will be beyond B release, and we need more resources to support Phase 2 and Phase 3, including:
  - Infrastructure resources, e.g. more bare metal machines in Spirent's VCT Lab
  - Developer resources in community to repeat the setup in various enviroments.
- Bin will create roadmap in wiki
- Bin will encourage community resources to repeat PoC setup in various environments

Actions include:

Sridhar to revise instructions of Steps 1 through 5 for shared tenant networks and using Neutron REST API to create networks
Sridhar to verify wiki documentation for accuracy and up-to-date
Sridhar to install SR2 and verify bug fixes
Bin to add roadmap in wiki documentation
Bin to work with Installers to confirm the end state of installation, i.e. neutron-l3-agent disabled or not, odl-l3 enabled or not
Bin to encourage community resources to repeat PoC setup in various environments
