Hi,

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:
[ovs]
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
ovs-vsctl add-port br-DATA_INTERFACE 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

31.xxx.yyy.0/24
31.xxx.yyy.0 Network
31.xxx.yyy.1 Gateway Address
31.xxx.yyy.2 to 31.xxx.yyy.254 Available ips

185.xxxx.yyyy.0/25
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.
