If my physical server ip is, in the physical server the openstack subnet create:

neutron subnet-create provider a.b.c.0/24 --name provider-sub --allocation-pool start=a.b.c.1,end=a.b.c.50 --dns-nameserver --gateway a.b.c.255

whether the a.b.c.x network segment should be in the network segment ?


I mean, if my server ip is, on it I install the openstack, when I set the provider network, whether I should set the 102.10.22.x -> 102.10.22.x ? or whether can I set other network segment such as 100.10.10.x-> 100.10.10.x.

Hello, Provider network is from which virtual instances are going to get IP's, it doesn't need to be same as flat physical network. you can set any network apart from 102.10.22.x / xx for your provider network.

I mean, if the physical server ip is, whether the openstack provider ip apart only can set the 102.10.22.x? , can not set to other network apart, such as 102.10.21.x, or 101.9.10.x
