Public bug reported: Hi colleagues,
I'm using Heat to provision Neutron and faced the bug which is rather Neutron's than Heat's, since Neutron receives all information, provisions control plane ('openstack port/router show' gives updated config), but do nothing in dataplane. My config, which I'm sending to Heat in order to change existing stack - https://pastebin.com/7J6emmSt Changes are: qnet2-gwport's ip_address changed from 1.1.1.1 to 1.1.1.2 Information about environment is below. After I apply changes, I see everything is updated to 1.1.1.2 in 'openstack show' outputs: $ openstack port show cbb4bb4b-7ce4-4e58-b81e-fc6262d8c53d [ ... ] | fixed_ips | ip_address='1.1.1.2', subnet_id='95f6bce5-cb46-43f6-86b5-16a71306e54e' | id | cbb4bb4b-7ce4-4e58-b81e-fc6262d8c53d | device_id | 771bbc70-a4e9-4f42-9c51-71ba3e6b525f $ openstack router show 771bbc70-a4e9-4f42-9c51-71ba3e6b525f [ ... ] | id | 771bbc70-a4e9-4f42-9c51-71ba3e6b525f | interfaces_info | [{"subnet_id": "95f6bce5-cb46-43f6-86b5-16a71306e54e", "ip_address": "1.1.1.2", "port_id": "cbb4bb4b-7ce4-4e58-b81e-fc6262d8c53d"}] but actual ip address in netns is old: # ip netns exec qrouter-771bbc70-a4e9-4f42-9c51-71ba3e6b525f ip a [ ... ] 265: qr-cbb4bb4b-7c: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1450 qdisc noqueue state UNKNOWN group default qlen 1000 link/ether d0:1c:a0:97:50:fb brd ff:ff:ff:ff:ff:ff inet 1.1.1.1/24 brd 1.1.1.255 scope global qr-cbb4bb4b-7c Logs with debug are available here - https://pastebin.com/Aj8WrGUt .
