                  Could somebody help me out with Neutron's Extraroute

                  The support status of the Extraroute is
                  support.UNSUPPORTED in heat, and only create and
                  delete are the supported operations.<br>

                <div>I think most of the resources when moved from
                  contrib to in-tree are marked as unsupported. Adding
                  routes to an existing router by multiple stacks can be
                  racy and is probably the reason use of this resource
                  is not encouraged and hence it's not supported. You
                  can see the discussion in the original patch that
                  proposed this resource <a

                <div>Not sure if things have changed on neutron side for
                  us to revisit the concerns.<br>
                </div>
                <div><br>
                </div>
                <div>Also it does not have any update_allowed
                  properties, hence no handle_update(). It would be
                  replaced if you change any property.</div>
                <div><br>

                <div>Hope it helps.<br>
