The Cisco Prime Network Registrar Caching DNS server can associate the client requests to the appropriate views on behalf of the Authoritative DNS server. This is done by configuring the DNS Views on the Caching DNS server and setting the uses-views attribute on the List/Add Exceptions page to true. The Caching DNS server maps the client to the appropriate view and tag the queries forwarded to the Authoritative DNS server with the appropriate view. Therefore, in these cases, the view mapping is done by the Caching DNS server.
