We have an issue on installing the openstack. Mainly we are struggling on the network of the openstack installation. We have 5 servers and installed each service in seperate servers ie.,
1st server: Controller, glance, keystone, dashboard
2nd Server: Nova compute
3rd " : Block storage (Cinder)
4th " : Object (Swift)
5th " : Network (neutron)

When we tried to configure the openswitch VLAN, we have stucked an area that is DATA_INTERFACE. Pleas have a look at the configuration mentioned below:

1. Configure OVS to use VLANS. Edit the /etc/neutron/plugins/openvswitch/ovs_neutron_plugin.ini file:
tenant_network_type = vlan
network_vlan_ranges = physnet1:1:4094
bridge_mappings = physnet1:br-DATA_INTERFACE

2.Create the bridge for DATA_INTERFACE and add DATA_INTERFACE to it:
ovs-vsctl add-br br-DATA_INTERFACE

3.Transfer the IP address for DATA_INTERFACE to the bridge in the same way that you transferred the EXTERNAL_INTERFACE IP address to br-ex. However, do not turn on promiscuous mode.


Please tell me which type of ip shall we assign here (public ip or private ip). We have ips on the range given below

Public subnet: 31.x.y.0/27
31.x.y.0 Network
31.x.y.1 Gateways
31.x.y.2 to 31.x.y.30 Available ips

Private subnet: 10.xx.yy.0/24
10.xx.yy.0 Network Address
10.xx.yy.1 gateway Address
10.xx.yy.2 to 10.xx.y.254 Available ips Network Gateway Address to Available ips

185.xxxx.yyyy.0 Network
185.xxxx.yyyy.1 Gateway
185.xxxx.yyyy.2 to 185.xxxx.yyyy.126 IPs
185.xxxx.yyyy.127 Broadcast

These are my ranges. Please suggest me which one we assign as DATA_INTERFACE, MGMT_INTERFACE and EXTERNAL_INTERFACE.??
We are waiting for your valuable updates.
