Title:
IPs from dhcp disabled subnets are added to host file when multiple
subnets
Status in OpenStack Neutron (virtual network service):
Fix Released
Bug description:
If a network has many subnets, and some have dhcp enabled and some
don't, then ips from all subnets are added to the dnsmasq host file.
Step:
$ neutron net-create net44
$ neutron subnet-create net44 10.0.10.0/24 --name sub1 --enable_dhcp true
$ neutron subnet-create net44 10.0.20.0/24 --name sub2 --enable_dhcp false
$ neutron subnet-list --fields id --fields name
