Sub-team Charter

Develops and Maintains L3 related components of Neutron.

Charter for Liberty

1. [IPAM] Support pluggable external IPAM
2. [Dynamic Routing] Integrate dynamic routing (with BGP implementation) with Neutron (not BGP/MPLS)
3. [DNS] Reconcile the DNS name of instances between Nova and Neutron. Once this is achieved, integrate Designate and Neutron
4. [Address Scopes] Implement Address Scopes as a first level abstraction in Neutron to improve the management or routable IPv4 and IPv6 ranges
5. [Network Segments] Add concept of L3 routed network segments (needs more definition)

Meetings

• Weekly on Thursday at 1500 UTC
• IRC channel: #openstack-meeting-3 on freenode
• Chair: Carl Baldwin (carl_baldwin)

Logs and Minutes

Meetings, with their notes and logs, will be found under http://eavesdrop.openstack.org/meetings/neutron_l3

Agenda

Updated: 2015-04-14

Announcements

• Liberty_Release_Schedule
• Adopt new spec process for Liberty
• Add your own action items. Please feel free. Look up meetbot for commands that you can use during the meeting.

Example: #action carl_baldwin will get something specific done this week.

Bugs

Critical

https://bugs.launchpad.net/neutron/+bug/1446261 gate-neutron-dsvm-functional race fails HA/DVR tests with network namespace not found

https://bugs.launchpad.net/neutron/+bug/1457900 dhcp_agents_per_network > 1 cause conflicts (NACKs) from dnsmasqs (break networks)

• Bugs Marked with at Least High Importance
• All Bugs Tagged with l3-ipam-dhcp

Blueprint: bgp-dynamic-routing

List of patches under review. Under each sub-heading, I recommend reviewing the patches in the order listed.

• Changes
  • Introduce routing instance entity
  • Introduce dynamic routing agent and agent scheduling
  • Add BGP driver and synchronise data between agent and API

• Testing
  • How to test the patches

Is worth to mention that Dynamic Routing spec is being re-designed for Kilo and some entities and concepts can change.

IPv6

After great progress was achieved in this area during the Kilo cycle, the IPv6 sub-group is being folded under the L3 team. We will continue tracking progress during the weekly meeting and in this page.

The status of IPV6 under Neutron as of the end of Kilo is summarized here: IPv6 Manual. Please feel free to correct any mistakes or add missing information.

Currently, IPv6 Tempest tests are being beefed up:

• https://bugs.launchpad.net/tempest/+bug/1401726 Tempest IPv6 scenario tests use IPv4 and floating IPs to connect and test

Open Discussion

• topic for May 7. ML3 plugin.

Other Blueprints

Blueprint: neutron-ovs-dvr

Distributed-Virtual-Router meetings are still on-going.

Need to keep an eye on the DVR tempest failure rate. This job is experimental but we hope to make it voting soon. It should have a similar failure rate to the full non-dvr tempest job.

Blueprint: dragonflow

This work is currently inactive while we work on DVR and a few other priorities.

Repo: https://github.com/stackforge/dragonflow
Blog: http://blog.gampel.net/2015/01/neutron-dvr-sdn-way.html

Blueprint: l3 plugin for routervm/modular l3 router plugin

This work will be resumed for Liberty. The blueprint will be updated for Liberty soon.

Need to discuss

• repository: in neutron or stackforge for Liberty?
  • plugin
  • reference implementation
  • config agent
