Creating Different Neutron Network Types

The following commands are examples of creating several different network types.

Create Shared Provider Networks

Flat Network

openstack --os-cloud default network create --share \
                                            --availability-zone-hint az1 \
                                            --external \
                                            --provider-network-type flat \
                                            --provider-physical-network physnet1 \
                                            flat

Flat Subnet

openstack --os-cloud default subnet create --subnet-range 172.16.24.0/22 \
                                           --gateway 172.16.24.2 \
                                           --dns-nameserver 172.16.24.2 \
                                           --allocation-pool start=172.16.25.150,end=172.16.25.200 \
                                           --dhcp \
                                           --network flat \
                                           flat_subnet

VLAN Network

openstack --os-cloud default network create --share \
                                            --availability-zone-hint az1 \
                                            --external \
                                            --provider-segment 404 \
                                            --provider-network-type vlan \
                                            --provider-physical-network physnet1 \
                                            vlan404

VLAN Subnet

openstack --os-cloud default subnet create --subnet-range 10.10.10.0/23 \
                                           --gateway 10.10.10.1 \
                                           --dns-nameserver 10.10.10.1 \
                                           --allocation-pool start=10.10.11.10,end=10.10.11.254 \
                                           --dhcp \
                                           --network vlan404 \
                                           vlan404_subnet

Creating Tenant type networks

L3 (Tenant) Network

openstack --os-cloud default network create l3

L3 (Tenant) Subnet

openstack --os-cloud default subnet create --subnet-range 10.0.10.0/24 \
                                           --gateway 10.0.10.1 \
                                           --dns-nameserver 1.1.1.1 \
                                           --allocation-pool start=10.0.10.2,end=10.0.10.254 \
                                           --dhcp \
                                           --network l3 \
                                           l3_subnet
