@JoeAldinger You can create NAD in primary role YAML below. This is true for 4.17 (Tech Preview) onwards.
apiVersion: k8s.cni.cncf.io/v1
kind: NetworkAttachmentDefinition
metadata:
name: l3-network
spec:
config: |2
{
"cniVersion": "0.3.1",
"name": "l3-network",
"type": "ovn-k8s-cni-overlay",
"topology":"layer3",
"subnets": "10.200.0.0/16/24",
"mtu": 1300,
"netAttachDefName": "a1/l3-network",
"role": "primary"
}
Before UDN that is prior to and including 4.16 NAD could only be used to create secondary NAD.
