Idempotence in the nmcli module with the 'route_metric4' parameter
Summary
I figured out some Idempotence in the nmcli module with the 'route_metric4' parameter. This issue is actual for both Ansible versions, 5.7 and 6.0. By default, the route metric value is '-1'. You can verify this if you run the 'nmcli conn sh eth0' command, for example.
ipv4.route-metric: -1 ipv4.route-table: 0 (unspec)
If we have this value in our host vars and no one other network parameter changes, the playbook with nmcli task nothing change on the target system. But only if we change any other network parameter 'route4', 'ipv6.method', doesn't matter, the 'route_metric4' parameter also will change from "-1" to -1.
- "ipv4.route-metric": "-1",
- "ipv4.route-metric": -1,
Of course, nothing has been changed on the target system finally, and 'nmcli conn sh' is showing the '-1' value as was before the playbook run. It looks no so good.

Steps to Reproduce
- name: Configure network interfaces via nmcli
community.general.nmcli:
conn_name: '{{ item.device }}'
ifname: '{{ item.device }}'
type: ethernet
ip4: '{{ item.ip4 }}'
gw4: '{{ item.gw }}'
routes4: '{{ item.routes }}'
method6: ignore
route_metric4: '{{ item.metric }}'
state: present
tags:
- 'network'
with_items: '{{ facts_ifaces }}'
The route_metric4 by default have value '-1'
{
"msg": [
{
"device": "eth0",
"gw": null,
"ip4": "xx.xx.xx.xx/24",
"metric": -1,
"routes": []
}
]
}
Expected Results
I expected the route metric didn't changed if in host_vars and in real system it value were similar, '-1' But when any other parameter will change for this interface the 'route_metric4' will change too.
