Please include this additional suggestions
If a node's primary network interface (e.g., eth0 or bond0) was configured during cluster installation, it cannot be reused to create additional networks. In such cases, you can use the OVNK localnet topology to create additional networks that connect to the underlying physical network, with or without VLAN tagging.

@dfitzmau This would LGTM as it is currently written.

@rameshsahoo111 your suggestion would only apply to versions where localnet topology is available and only for pod secondary networks, not for the case where you need to make some networks accessible to the nodes (e.g. to access some storage backend). If we are to include your suggestion, we would need to explain these limitations.
