= Sub-team Charter =
 
 
 
Develops and Maintains L3 related components of Neutron.
 
 
 
== Team Charter for Liberty ==
 
# [IPAM] Support pluggable external IPAM
 
# [Dynamic Routing] Integrate dynamic routing (with BGP implementation) with Neutron (not BGP/MPLS)
 
# [DNS] Reconcile the DNS name of instances between Nova and Neutron. Once this is achieved, integrate Designate and Neutron
 
# [Address Scopes] Implement Address Scopes as a first level abstraction in Neutron to improve the management or routable IPv4 and IPv6 ranges
 
# [Network Segments] Add concept of L3 routed network segments (needs more definition)

The status of IPV6 under Neutron as of the end of Kilo is summarized here: [https://wiki.openstack.org/wiki/NEUTRON-IPV6-MANUAL 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
 
 
 
Bugs which need discussion:
 
 
 
* https://launchpad.net/bugs/1460720 bug 1460720 Move ipv6_gateway L3 config to CLI
