NetworkAttachmentDefinitions
The NetworkAttachmentDefinition resource allows you to use custom networks in addition to the main Cilium CNI when the shturval-metacni module is installed.
NetworkAttachmentDefinition is created automatically when SriovNetwork is created. For the created NetworkAttachmentDefinition, only labels and annotations can be changed. To change the specification itself, change the network policy SriovNetworkNodePolicy.
To independently add a new NetworkAttachmentDefinition resource on the NetworkAttachmentDefinitions page of the Networks section, click “+ Add NetworkAttachmentDefinition”.

Specify the name of the resource and select the namespace in which it will be used. Specify labels and annotations as needed.
The specification block contains the configuration of the user resource. It must contain specification parameters in JSON format.
Example
```JSON config: '{ "cniVersion": "0.3.1", "name": "my-multus-network", "type": "macvlan", "master": "eth0", "mode": "bridge", "ipam": { "type": "host-local", "subnet": "192.168.1.0/24", "rangeStart": "192.168.1.200", "rangeEnd": "192.168.1.216", "routes": [{ "dst": "0.0.0.0/0" }], "gateway": "192.168.1.1" } }' ```Description of specification fields:
- cniVersion: CNI version.
- name: Network name.
- type: Network interface type. For example, macvlan.
- master: The name of the main network interface on the Kubernetes node.
- mode: operating mode.
