in http://docs.openstack.org/mitaka/inst...

i only choose option 2 and install with option 2 procedure

Networking Option 2: Self-service networks http://docs.openstack.org/mitaka/inst...

do i need to go through and install option 1? http://docs.openstack.org/mitaka/inst...

after succeed to launch neutron server, i go to next step procedure

but in http://docs.openstack.org/mitaka/inst...

it warn me You must create the provider network before the self-service network.

i do not know whether it talking about http://docs.openstack.org/mitaka/inst...

but i think it is talking about http://docs.openstack.org/mitaka/inst...

originally i missed this link provider network and create self-service network first and then discover the link http://docs.openstack.org/mitaka/inst...

i just confused that i have not installed option 1 but why in next step to create subnet need to create provider network ?

neutron subnet-create --name provider \
  --allocation-pool start=192.168.20.2,end=192.168.20.10 \
  --dns-nameserver 8.8.8.8 --gateway 192.168.20.1 \
  provider 192.168.20.0/24


neutron subnet-create --name selfservice \
  --dns-nameserver 8.8.8.8 --gateway 192.168.20.1 \
  selfservice 192.168.20.0/24
