[Steps to reproduce] 0) Deploy a cloud with l3ha enabled - If familiar with juju, it's possible to use this bundle http://paste.ubuntu.com/24707730/ , but the deployment tool is not relevant 1) Once it's deployed, configure it and create a router see https://docs.openstack.org/mitaka/networking-guide/deploy-lb-ha-vrrp.html ) - This is the script used during the troubleshooting -----8<------ #!/bin/bash -x source novarc # admin neutron net-create ext-net --router:external True --provider:physical_network physnet1 --provider:network_type flat neutron subnet-create ext-net 10.5.0.0/16 --name ext-subnet --allocation-pool start=10.5.254.100,end=10.5.254.199 --disable-dhcp --gateway 10.5.0.1 --dns-nameserver 10.5.0.3 keystone tenant-create --name demo 2>/dev/null keystone user-role-add --user admin --tenant demo --role Admin 2>/dev/null export TENANT_ID_DEMO=$(keystone tenant-list | grep demo | awk -F'|' '{print $2}' | tr -d ' ' 2>/dev/null ) neutron net-create demo-net --tenant-id ${TENANT_ID_DEMO} --provider:network_type vxlan env OS_TENANT_NAME=demo neutron subnet-create demo-net 192.168.1.0/24 --name demo-subnet --gateway 192.168.1.1 env OS_TENANT_NAME=demo neutron router-create demo-router env OS_TENANT_NAME=demo neutron router-interface-add demo-router demo-subnet env OS_TENANT_NAME=demo neutron router-gateway-set demo-router ext-net # verification neutron net-list neutron l3-agent-list-hosting-router demo-router neutron router-port-list demo-router ----- 8< ------- 2) Kill the associated master keepalived process for the router ps aux | grep keepalived | grep $ROUTER_ID kill $PID 3) Wait until "neutron l3-agent-list-hosting-router demo-router" shows the other host as active 4) Check the binding:host_id property for the interfaces of the router for ID in `neutron port-list --device-id $ROUTER_ID | tail -n +4 | head -n -1| awk -F' ' '{print $2}' `; do neutron port-show $ID ; done Expected results: The interface where the device_owner is network:router_gateway has its property binding:host_id set to where the keepalived process is master Actual result: The binding:host_id is never updated, it stays set with the value obtainer during the creation of the port.
