Configuring INS DNS for Selected or Changed Zone Push
Cisco Prime Network Registrar IPAM has the ability to perform selective DNS zone
configurations using the Configuration/Deployment menu option.
Figure 7-1 Configuration/Deployment
Specific Configuration/Deployment options include the following:
•
DNS Configuration - Changed Zones Only - when an administrator makes a
change to a resource record in a domain, all zones associated with that domain are
marked as "dirty". The Cisco Prime Network Registrar IPAM administrator can then
schedule a “Changed Zones Only” deployment push, and only zones that have
changed since the last file generation will be created and sent to the DNS server.
•
DNS Configuration - Selected Zones Only - an administrator may want to
immediately push changes to a specific zone to a specified DNS server, without
necessarily pushing every changed zone.
To support either of these configuration/deployment options, some additional configuration
is required on the DNS server. This is because these tasks make use of the “rndc” utility to
only load the selected zones, instead of forcing the DNS service to completely stop and start.
This provides seamless loading of new data without affecting name resolution for your users.
