commit b847cd02c56dc8fe654f4731306dc2b5493a62eb Author: Brian Haley <[email protected]> Date: Thu Oct 25 14:41:19 2018 -0400 Enable 'all' IPv6 forwarding knob correctly When the external gateway is plugged and we enable IPv6 forwarding on it, make sure the 'all' sysctl knob is also enabled, else IPv6 packets will not be forwarded. This seems to only affect HA routers that default to disabling this 'all' knob on creation. Also, when we are removing all the IPv6 addresses from a HA router internal interface, set 'accept_ra' to zero so it doesn't accidentally auto-configure an address. Set it back to one when adding them back. Re-homed newly added _wait_until_ipv6_forwarding_has_state() accordingly.

Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1787919 Title: Upgrade router to L3 HA broke IPv6 Status in neutron: Fix Released Bug description: When I disabled a router, changed it to L3 HA and enabled it again all the logic that was implemented in [1] did not seem to work. Please see the thread on ML [2] for details. The backup router had the net.ipv6.conf.qr-<interface>.accept_ra values for the qr interfaces (one for ipv4 and one for ipv6) set to 1. On the active router the net.ipv6.conf.all.forwarding option was set to 0. After removing SLAAC addresses on the backup router, setting accept_ra to 0 and enabling ipv6 forwarding on the active router it started working again. Please let me know if you need anything to troubleshoot this here or on IRC (tobias-urdin).
