How to loop over hashes having an undefined number of sub-elements?

Hi everyone,

This is a tricky question which I have been unable to solve so far despîte multiple attempts, maybe it is not feasible with Ansible.
I pull some facts from a networking device, some of them end up in {{ facts.ansible_facts.ansible_net_neighbors }}:

“ansible_net_neighbors”: {
“Gi0/0”: [
{
“host”: “IOSv_L2_10.actionmystique.net”,
“port”: “Gi0/1”
}
],
“Gi0/3”: [
{
“host”: “IOSv_Leaf_13.actionmystique.net”,
“port”: “Gi0/1.10”
},
{
“host”: “IOSv_Leaf_13.actionmystique.net”,
“port”: “Gi0/1.20”
},
{
“host”: “IOSv_Leaf_13.actionmystique.net”,
“port”: “Gi0/1”
}
],
“Gi0/4”: [
{
“host”: “IOSv_Leaf_14.actionmystique.net”,
“port”: “Gi0/1”
},
{
“host”: “IOSv_Leaf_14.actionmystique.net”,
“port”: “Gi0/1.20”
},
{
“host”: “IOSv_Leaf_14.actionmystique.net”,
“port”: “Gi0/1.10”
}
],

…
The number & names of ansible_net_neighbors sub-elements “Gin/p” (which stand for GigabitEthernet n/p) are dynamic: we have no clue in advance what they’ll be.
Same characteristic for the number of host/port duo(s) inside each “Gin/p”

So, how can I loop over all those sub-elements? The tricky part for me is the fact that there is no name for the field “Gin/p”.
I have unsuccessfully tried the following for instance:

  • name: Updating the description of all interfaces
    ios_config:
    provider: “{{ connections.ssh }}”
    parents:
  • “interface {{ item }}”
    lines:
  • “description Connected to {{ item.host }} on its port {{ item.port }}”
    with_dict: “{{ facts.ansible_facts.ansible_net_neighbors }}”
    register: result

Any ingenious trick in mind?
