[Bug 1581933] Re: RBAC "access_as_external" policy on in-use internal netwok

 

External networks are normal networks that allow router gateway
interfaces to be attached to them. VMs have no impact on a network's
candidacy for being an external network.

Title:
  RBAC "access_as_external" policy on in-use internal netwok

Status in neutron:
  Invalid

Bug description:
  When the internal network have ports in use, a rbac
  "access_as_external" policy should not be allowed. We should have an
  error message explaining that.

  When we execute such an action, the "router:external" for the internal network becomes "true"

  But the network has ports assigned to internal purposes like VM or
  internal router interface and it opens many spots for errors .
