Bug reporter was using dnsmasq version 2.66, which has dnsmasq address resolving issues when the same mac is used for both IPv4 and IPv6 addresses. I was able to reproduce the issue he reported with dnsmasq 2.66. With dnsmasq 2.67 the issue is not seen and this is the openstack neutron recommended version for IPv6.
Please use dnsmasq 2.67 to resolve this issue. I see the same issue when a port created with extra_dhcp_opts on a network having IPv6 stateless subnet and IPv4 subnet. I have raised a seperated bug https://bugs.launchpad.net/neutron/+bug/1466144 to track issue with extra_dhcp_opts ** Changed in: neutron Status: In Progress => Invalid ** Changed in: neutron Assignee: venkata anil (anil-venkata) => (unassigned) -- You received this bug notification because you are a member of Yahoo!
