Don't make your life complicated, just enjoy the blog. ^_^
This is my first time to create Blog. Please pardon my simplicity of my own blog and look for the content. Enjoy reading! ^_^

In this blog I will configure two networks and create a router to allow communication between the networks.

OpenStack Networking allows you to create and manage network objects, such as networks, subnets, and ports, which other OpenStack services can use. Plug-ins can be implemented to accommodate different networking equipment and software, providing flexibility to OpenStack architecture and deployment.

The first step you need to do is to create networks.

Browse the network section you created in the web interface.

http://[your IP Address]/dashboard/project/networks/

This should be the IP address of the server on the host-only network.

Create a Network named GREEN

Create a GREEN_SN subnet with the network address 192.168.0.0/24

Create a BLUE network and BLUE_SN subnet with the network address 192.168.1.0/24

Now, create Instances

Browse to the instance section of the web interface
http://[your IP Address]/dashboard/project/instances/

Launch 2 instances with the name GREEN

Select the Source*

Select the source cirros-0.4.0-x86_64-disk
Set Create New Volume to No

Select the Flavor*

Select the flavour m1.nano

Select the GREEN network and launch the instances

Repeat with 1 instance in the BLUE network

Now, browse the GREEN_1 console and log-in.
Note: the console take some time.

Ping GREEN_2 you should get a response

Ping BLUE and you should not get no response

Browse the Network Topology section and view the Graph
copy & paste it to your URL for easy access: 
http://put your IP Address/dashboard/project/routers/

Create a Router

copy & paste it to your URL for easy access: 

http://put your IP Address/dashboard/project/routers/

Create ROUTER_1

Edit the ROUTER_1 and ADD both GREEN and BLUE 

network interfaces. 

Then repeat it to GREEN network interfaces.

Return to the GREEN_1 instance console

 and ping BLUE.

You should ping and connect.
