Title:
  DHCP offer wrong router

Status in neutron:
  Won't Fix

Bug description:
  Hello, 
  I have a public network with 3 sub-nets and associated gateways: 
  public3	XX.0/27 	IPv4 	XX.30 	 
  public	XX.64/28 	IPv4 	XX.78 	 
  public2	XX.160/28 	IPv4 	XX.174 	

  From time to time, I saw that on instantiated VM, the default route to
  the GW was missing.

  Checking the DHCP answer, I noticed the proposed router was a wrong
  one.

  We get the .174 instead of .78

  see below DHCP offer :

  Could that it be an issue related to multiples sub-nets?
