Title:
  routed provider networks limit to one host

Status in neutron:
  Fix Released

Bug description:
  There seems to be limitation for a compute node to only have interface
  on one segment in a multisegment network. This feels wrong and limits
  the compute resources since they can only be part of one segment.

  The purpose of multi segment networks is to group multiple segments
  under one network name. i.e. operators should be able to expand the IP
  pool without having to create multiple network for it like internet1,
  internet2, etc.

  The way it should work is that a compute node can belong to one or
  more segments. It should be up to the operator to decide how they want
  to segment the compute resources or not. It should not be enforced by
  the simple need to add IP ranges to a network.

  way to reproduce.
  1. configure compute nodes to have bridges configured on 2 segments
  2. create a network with 2 segments.
  3. create the segments
