Public bug reported: When L3HA router is created, it is first transitioned to backup on all nodes. In such case IPv6 forwarding is disabled in router's namespace. It was introduced by commit https://github.com/openstack/neutron/commit/676a3ebe2f5b62f0ce7a3f7f434526931d5504a5
Later router is transitioned to be master on one of nodes. And then IPv6 forwarding should be enabled. Unfortunately it is enabled only when gateway is configured: https://github.com/openstack/neutron/blob/929d3fe9f49aeea817c8a922d0b28d605cc9b562/neutron/agent/l3/router_info.py#L704 So if there is no gateway connected to router and it has only tenant networks ports, IPv6 forwarding will not be turned on and IPv6 connectivity between subnets will not be possible. ** Affects: neutron Importance: High Assignee: Slawek Kaplonski (slaweq) Status: New ** Tags: l3-ha -- You received this bug notification because you are a member of Yahoo!
