I wish to install openstack for internal use using 2 Ubuntu 16.04 servers that are on the same network. Access to openstack would be given only to other devices connected on the same network. Currently public access or provider services are not required. Could anyone suggest how i can proceed with the install? I followed the Openstack netwon installation guide. But i am confused with the networking steps pertaining to configuration of provider/self service networks.

What do you mean you do not have provider network? And which steps are confusing for you?

Basically i want to know if i can have the installation done with only one network. My current network is in 10.x.x.x series. So i want to use the same for external access and management. How can i proceed?

I run Packstack with a single network. First, follow the packstack quickstart guide to set up an all-in-one node, then add a compute node. Adding the compute requires minimal changes to the packstack config file (named "answerfile"). Packstack uses OVS by default, not Linuxbridge.

Thanks for the suggestion @Bernd Bausch But i am more keen on learning the networking concepts for which i want to deploy openstack manually. So any tips on the manual config of networks? Currently i only have one physical switch, so one network it is.

The installation guide asks for a mgmt and a provider network with different address ranges. Use your interface, e.g. eth0, for PROVIDER_INTERFACE_NAME and INTERFACE_NAME in the guide. Use eth0's IP address for OVERLAY_INTERFACE_IP_ADDRESS. Or configure a second IP address on eth0 and use it.
