Description Gris Ge 2019-09-03 13:45:59 UTC
Description of problem:

When DNS is configured on the interface with static default gateway,

applying the empty state via libnmstate or nmstatectl will cause OS lose
the static default gateway.


Version-Release number of selected component (if applicable):
nmstate-0.0.8-12.el8

How reproducible:
100%

Steps to Reproduce:
1. Set a interface with static address, default gateway, dns nameserver using nmcli or this nmsate state file :


---
dns-resolver:
  config:
    search: []
    server:
    - 192.168.122.1
routes:
  config:
  - destination: 0.0.0.0/0
    next-hop-address: 192.168.122.1
    next-hop-interface: eth1
interfaces:
- name: eth1
  type: ethernet
  state: up
  ipv4:
    address:
    - ip: 192.168.122.8
      prefix-length: 24
    dhcp: false
    enabled: true


2. Apply the empty state via nmstatectl.

3. Use `ip route` to check the static default gateway.

Actual results:

The static default gateway gone.

Expected results:

The static default gateway is untouched.
