Steve thanks for Reply, Actaully we need to make a controller node using contrail 3.0 and openstack Kilo which is straight forward from Juniper contrail-installer-package link, which we are not able to download.
I'm not sure how the packages match up between the Juniper releases and the Open Contral ones. If you want the Juniper release select the option to open the customer care ticket and ask for it. The worst they can say is that you don't qualify.
