What's Coming for IPv6 and L3 in Neutron

Sign up or log in to save this to your schedule and see who's attending!

IPv6 in OpenStack Neutron has made progress enough that the addressing and L2 issues have been resolved.  Neutron still faces a number of issues when it comes to IPv6 and L3.  This talk will discuss these issues and how the Neutron team is addressing them in Kilo and future releases.

Routing IPv6 to and from the cloud requires out-of-band steps including the delegation of real routable IP addresses and completing the route to the Nuetron IPv6 subnet.  We will discuss improvements in Kilo to IP address management that will accomodate IPv6 delegation.  To complete the routing circuit post-Kilo, Neutron will integrate externally using protocols like BGP or IPv6 prefix delegation.

The reference L3 implementation in Kilo makes assumptions that restrict full IPv6 operation such as multiple IP addresses on a port and dual-stack routing.  Enhancements are planned for post-Kilo to address the L3 agent's short-comings.

Finally, we will discuss the inclusion of distributed routing for IPv6 after Kilo
