A VM with an IP address in a OVN localnet network is unreachable from other VMs/Pods running in the same node and using the pod network. VMs/Pods running in different nodes work fine.

1. Create a localnet mapping and net-attach-def:

```
apiVersion: nmstate.io/v1
kind: NodeNetworkConfigurationPolicy
metadata:
  name: localnet-mappings
spec:
  desiredState:
    ovn:
      bridge-mappings:
      - bridge: br-ex
        localnet: ovn-localnet-1
        state: present
```

```
apiVersion: k8s.cni.cncf.io/v1
kind: NetworkAttachmentDefinition
metadata:
  name: localnet-network
  namespace: test
spec:
  config: |
    {
            "cniVersion": "0.3.1",
            "name": "ovn-localnet-1",
            "type": "ovn-k8s-cni-overlay",
            "topology": "localnet",
            "netAttachDefName": "test/localnet-network"
    }
```

2. Create a target VM with its only NIC using the test/localnet-network NAD
3. Create a test VM (or pod) with its only NIC in the pod network
4. Ping from the test VM to the target VM. Compare the results from both VMs running in the same node or in different nodes.

The ping from the test VM to the target VM only works if they are in different nodes.

Ping always working.
