Title:
  routing policy not always applied on systemd-networkd restart

Status in systemd package in Ubuntu:
  New

Bug description:
  We are using ubuntu 18.04 in an environment with two NIC in the same
  subnet.

  As part of network configuration we have created a routing table for
  each NIC.

  Every other time that we restart networkd we lose connectivity to
  eth0. After tcpdump we noticed the reason we lose connectivity to eht0
  is routing problem. All connection will always go out from eht1.

  If we restart netowrkd one more time this will fix the routing issue instantly. 
  Also on each reboot routing policy applies correctly.

  The problem only appears when we restart netwrokd every other time.

  We already have raised this issue with Netplan and they suggest this
  is a systemd bug.

  Please find the debugs in the attachments. Please don't hesitate to
  ask if you require any further logs.

  Regards
  Arash
