[Bug 1581935] Re: update "--router:external" attribute to true should be blocked when network has ports in use

 

An external network and regular network are the same. The only
difference is that a router gateway port can attach to an external one.
There is no reason to block changes to an external network because VMs
can be attached to an external network.

Title:
  update "--router:external" attribute to true should be blocked when
  network has ports in use

Status in neutron:
  Opinion

Bug description:
  Network update "--router:external" attribute should be blocked if the
  network has ports in use ( not including qdhcp port)

  When a network with a port attached to a VM turnes to be external, it
  can make an opening to issues of qdhcp NS for this network, The VMs on
  this network. If the network was attached as internal interface on a
  router and becomes external , there is a contrast between the network
  role ( external) to network usage ( attached as internal )
