• Team meeting
  • For now, attend the DVR meeting
  • Wednesdays at 1600 UTC ? Thursdays at 1500 UTC ?
• DVR
  • F2F was very productive.
    • DVR Team updated the OpenStack Community on what has changed from the earlier proposal.
      • No kernel Module
      • Use existing namespaces
      • Split L3, Floating IP and default External Access.
      • Provide migration Path
      • Supporting both East-West and North-South.
    • Got a clear direction from the PTL that we don’t need to address the distributed SNAT at this point of time and focus on the centralized solution that we proposed.
    • The DVR Agent design (both L2 and L3) should be discussed with the respective teams before we proceed. Probably a separate document or blueprint that discusses the flows.
    • No support for Dynamic routing protocols.
    • Discussed both active blueprints.(
    • Community suggested that we need to consider or check if the OVS ARP responder can be utilized.
    • HA for the Centralized Service Node (l3-high-availability)
• L3 Agent consolidation
  • New patch is up. https://review.openstack.org/#/c/57627/
• HA Routers
  • All patches are submitted, the agent patch has to be reworked a bit to leverage the changes made in the keepalived patch and the conntrackd patch written by Assaf Muller. I think Assaf's patch should also be reworked since I have introduced some new features to the external_process package. I already have a new version of the agent which uses the keepalived changes but I didn't submit yet. I'm currently on vacation, and I'll be back in 2 weeks. Regards,
