Hi,
Can You maybe give us some more details? Like how exactly this network and subnets looks like (neutron net-show and neutron subnet-show), and please also check dnsmasq config files - those are located on node where DHCP agent is running. If You will do something like:
ps aux | grep <network_id>
You will find dnsmasq process for this network.

Hello Everyone, I have an openstack queens installation based on centos 7. I created a shared vlan network and multiple subnet under it. When I start an instance on one of the subnet network it gets the correct ip based on its subnet but the gateway seems random (one of the subnet of the vlan).
Any suggestion, please ?
Ignazio
