# OVN4NFV Usage guide
## Quickstart Installation Guide
Please follow the ovn4nfv installation steps - [ovn4nfv installation](https://github.com/ovn4nfv/ovn4nfv-k8s-plugin#quickstart-installation-guide)
## Network Testing
create 2 pod and test the ping operation between them
```
# kubectl apply -f example/ovn4nfv-deployment-replica-2-noannotation.yaml
deployment.apps/ovn4nfv-deployment-noannotation created
# kubectl get pods -o wide
NAMESPACE NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES

```
Create hostname deployment and svc and test the k8s service query
```

```
you should get different hostname for each query
Test the reachablity
```
# kubectl exec -it ovn4nfv-deployment-noannotation-sandbox-5fb94db669-vdkss -- wget -qO- example.com

## Test the Multiple Network Setup and Testing
Create two networks ovn-priv-net and ovn-port-net
```
# kubectl apply -f example/ovn-priv-net.yaml
network.k8s.plugin.opnfv.org/ovn-priv-net created
# kubectl apply -f example/ovn-port-net.yaml
network.k8s.plugin.opnfv.org/ovn-port-net created

```
Use the network `ovn-port-net` and `ovn-priv-net` for the multiple network creation
and test the network connectivity between the pods

## VLAN and Direct Provider Network Setup and Testing
In this `./example` folder, OVN4NFV-plugin daemonset yaml file, VLAN and direct Provider networking testing scenarios and required sample
configuration file.
### Quick start
### Creating sandbox environment
Create 2 VMs in your setup. The recommended way of creating the sandbox is through KUD. Please follow the all-in-one setup in KUD. This
will create two VMs and provide the required sandbox.
### VLAN Tagging Provider network testing
The following setup have 2 VMs with one VM having Kubernetes setup with OVN4NFVk8s plugin and another VM act as provider networking to do
testing.
Run the following yaml file to test teh vlan tagging provider networking. User required to change the `providerInterfaceName` and
`nodeLabelList` in the `ovn4nfv_vlan_pn.yml`
```
kubectl apply -f ovn4nfv_vlan_pn.yml
```
This create Vlan tagging interface eth0.100 in VM1 and two pods for the deployment `pnw-original-vlan-1` and `pnw-original-vlan-2` in VM.
Test the interface details and inter network communication between `net0` interfaces
```

```
Test the ping operation between the vlan interfaces
```
# kubectl exec -it pnw-original-vlan-2-5bd9ffbf5c-4gcgq -- ping -I net0 172.16.33.3 -c 2
PING 172.16.33.3 (172.16.33.3): 56 data bytes

2 packets transmitted, 2 packets received, 0% packet loss
round-trip min/avg/max = 0.092/0.098/0.105 ms
```
In VM2 create a Vlan tagging for eth0 as eth0.100 and configure the IP address as
```
# ifconfig eth0.100
eth0.100: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

RX errors 0 dropped 0 overruns 0 frame 0
TX packets 149 bytes 12698 (12.6 KB)

```
Pinging from VM2 through eth0.100 to pod 1 in VM1 should be successfull to test the VLAN tagging
```
# ping -I eth0.100 172.16.33.3 -c 2

### VLAN Tagging between VMs
### Direct Provider network testing
The main difference between Vlan tagging and Direct provider networking is that VLAN logical interface is created and then ports are
attached to it. In order to validate the direct provider networking connectivity, we create VLAN tagging between VM1 & VM2 and test the
connectivity as follow.
Create VLAN tagging interface eth0.101 in VM1 and VM2. Just add `providerInterfaceName: eth0.101' in Direct provider network CR.
```
# kubectl apply -f ovn4nfv_direct_pn.yml
```
Check the inter connection between direct provider network pods as follow
```
# kubectl exec -it pnw-original-direct-1-85f5b45fdd-qq6xc -- ifconfig

# Summary
This is only the test scenario for development and also for verification purpose. Work in progress to make the end2end testing
automatic.
