+## Usage
+Create terraform.tfvars, it would looks like:
+```
+$ cat terraform.tfvars
+```
+
+```
+auth_url = "XXX"
+region = "XXX"
+
+#credentials tenant A
+name_project_A = "XXXXXX"
+user_project_A = "XXXXXX"
+pwd_project_A = "XXXXXX"
+
+#credentials tenant B:
+name_project_B = "XXXXXX"
+user_project_B = "XXXXXX"
+pwd_project_B = "XXXXXX"
+
+image_name = "XXXXXX"
+flavor_name = "XXXXXX"
+
+#To make it easy, keys would be the same and created before in the 2 tenants
+key_pair_project_A = "XXXXXX"
+key_pair_project_B = "XXXXXX"
+```
+Create the stack:
+```
+$ terraform init
+$ terraform apply -parallelism=1
+```
+
+We can generate hosts file to be used by ansible to play playbook on it using terraform-inventory:
+
+```
+$ terraform-inventory -u <SSH_USER_bastion> -k <SSH_PRIVATE_KEY> -o hosts/<enviroment>.yml
+```
+
+Modify/Check generated file to look like:
+
+```
+[bastion]
+bastion_server_A ansible_host=xx.xx.xx.182 ansible_user=cloud ansible_ssh_private_key_file=/path/private-key ansible_ssh_common_args='-o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no'
+bastion_server_B ansible_host=xx.xx.xx.186 ansible_user=cloud ansible_ssh_private_key_file=/path/private-key ansible_ssh_common_args='-o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no'
+
+[project_A]
+backend_server_A ansible_host=192.168.20.3 ansible_user=cloud ansible_ssh_private_key_file=/path/private-key ansible_ssh_common_args='-o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -o ProxyCommand="ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -W %h:%p -i /path/private-key [email protected]"'
+
+[project_B]
+backend_server_B ansible_host=192.168.30.3 ansible_user=cloud ansible_ssh_private_key_file=/path/private-key ansible_ssh_common_args='-o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -o ProxyCommand="ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -W %h:%p -i /path/private-key [email protected]"'
+```
+Start the playbook that will start tmux in backends and play ping between them:
+```
+$ansible-playbook -i hosts/<enviroment> playbook.yml
+```
+
+ssh to bastion, from and ssh to his backend and attach to the opened tmux session by ansible:
+```
+$ssh USER@bastion-ip
+$ssh USER@backend-ip
+$ tmux a
+```
+Create route-target between tenants by starting the script setup_inter_tenant_x-x.yml in bastion of the enviroment (sudo password is asked):
+there are 2 files: setup_inter_tenant_2-21.yml for contrail-2.21 and setup_inter_tenant_3-2.yml for contrail-3.2
+
+First, create the file vars/<enviroment>.yml specific for each enviroment, it seems like:
+
+```
+tenant_name: ""
+user_name: ""
+password: ""
+server_ip: ""
+auth_plugin: ""
+auth_url: ""
+asn: ""
+```
+Create the route-target:
+
+```
+$ ansible-playbook -K -i <bastion> @vars/<enviroment>, setup_inter_tenant_3-2.yml 
+```
+Check the ping in tmux you'll see the succes ping between tenants VMs
