Hi, all Subnet's nameserver is out of order. That is to say, cmd "neutron subnet-update [subnet-id] ----dns_nameservers list=true 1.2.3.4 5.6.7.8" and "neutron subnet-update [subnet-id] ----dns_nameservers list=true 5.6.7.8 1.2.3.4" is same. I think that we often have two or more dns nameservers, one is a main nameserver, another is a backup. Therefore, I think we should make difference of the above command. Does anyone have ideas?
