Title:
  default gateway route not installed for bond interfaces through reboot

Status in ifupdown package in Ubuntu:
  Confirmed

Bug description:
  Expectation:  After reboot, route for default gateway specified on
  bonded interface is installed according to "gateway x.x.x.x"  (where
  x.x.x.x is a valid IPv4 address) specified in /etc/network/interfaces
  or files sourced per /etc/network/interfaces

  Actual Result: After reboot, route is not installed. Interface does
  work otherwise (I can ping the gateway on that subnet, for instance).
  'ifdown -a' followed by  'ifup -a' (run with proper permission... so
  sudo) brings the gateway back until next reboot.

  Package:  I'm not familiar enough to be certain what is causing this,
  but I was seeing this in beta2 of 16.04 as well.
