Hello Paritosh Arya,
Thank you for using our services.
It is preferable that you add the secondary membership and role provider (DB based) in the configuration of the website so that you can set permissions for the roles coming from this provider. That is if you need to set View permissions for your CMS pages to users coming from the DB membership and role providers.
