Sub-team Charter

Develops and Maintains L3 related components of Neutron.

Team 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)



https://bugs.launchpad.net/neutron/+bug/1494114 - Bad router request: Router already has a port on subnet


https://bugs.launchpad.net/neutron/+bug/1404743 sporadic test failures due to VMs not getting a DHCP lease
https://bugs.launchpad.net/neutron/+bug/1469322 Associating a floatingip with a dual stack port requires the fixed-address to be specified

Routing Network Segments

(was pluggable-ext-net)

Specifications routing-networks
RFE Routing Network Segments

Superseded spec: https://review.openstack.org/#/c/88619/

Juno Design Summit: Session, Etherpad


Specifications dynamic routing use cases,

Dynamic Routing Kilo spec

Gerrit Topics bp/bgp-dynamic-routing

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

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

IPv6 Prefix Delegation

Re-proposed and approved for Liberty. Code and documentaion on gerrit for review.

Patches out for review, in order of precedence:


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:

Bugs which need discussion:

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.

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
