I am using multus-cni to create multiple interfaces in my pod. I have weave-net CNI configured so pods come up with cluster ip 10.32.x.x. Using the below network-attachment-definition , I am able to bring up multiple interfaces inside a pod with IP addresses 10.32.0.180-199 but these IP addresses are unreachable from other pods in the same cluster. If I do kubectl exec into another pod, and ping 10.32.0.180, I am not able to ping that IP.

Can anyone tell me what needs to be done so that the additional interfaces in the pod are reachable within the cluster?

apiVersion: "k8s.cni.cncf.io/v1"
kind: NetworkAttachmentDefinition
metadata:
  name: macvlan-conf
spec:
  config: '{
      "cniVersion": "0.3.0",
      "type": "macvlan",
      "master": "{{ .Values.global.interfaceName }}",
      "mode": "bridge",
      "ipam": {
        "type": "host-local",
        "subnet": "10.32.0.0/16",
        "rangeStart": "10.32.0.180",
        "rangeEnd": "10.32.0.199",
        "routes": [
          { "dst": "0.0.0.0/0" }
        ],
        "gateway": "10.32.0.1"
      }
    }'
