Fixed In Version:	openstack-neutron-2014.2.2-1.el7ost	Doc Type:	Enhancement
Doc Text:	Tenant networks can now be created that use the 'dnsmasq' process inside the DHCP agent to serve additional configuration to IPv6 DHCP clients, including addressing and support for IPv6 stateful subnets. Note that the default gateway is still set by Router Advertisement messages sent by the L3 agent. IMPORTANT: This feature requires dnsmasq-2.66-13.el7_1 or later.	Story Points:	---

Description RHOS Integration 2013-12-18 02:24:56 UTC

Cloned from launchpad blueprint https://blueprints.launchpad.net/neutron/+spec/dnsmasq-ipv6-dhcpv6-stateful.

Description:

The intent of this blueprint is to allow dnsmasq to work in DHCPv6 Stateful mode, i.e. sending out RA to tenant network with A bit set to 0 and LMO bits set to 1. As the result, VM will use dnsmasq as DHCPv6 server for address assignment and optional information. At the same time, VM will continue to rely on RA for default route.
