@jkbundala, is there a reason why you are using an unreleased, unsupported version open-release/juniper.alpha1 instead of the latest open-release/ironwood.2 release? If this is a production or production-like deployment, I’d strongly recommend using the Ironwood version.

However, if you are using this installation to test the Juniper release, you should update the title of this forum thread to include Juniper alpha as mentioned in this post and ping nedbat with more details.
