When the Notify option is enabled, a primary DNS server sends messages to
secondary servers informing them that the zone has changed. After a secondary
receives a notify message, it requests a zone transfer from the primary. The
Notify and Notify Additional Servers deployment options can be set
at the following levels:
- Configuration
- Server group
- Server
- View
- Zone
- IP block
- IP network
When you deploy a zone that has been assigned a primary deployment role and at least one secondary deployment role, the Notify setting is automatically set to Automatically Notify servers listed on the Name Servers tab. In this case, Address Manager uses the deployment roles to determine these settings and doesn't require you to manually configure the Notify and Notify Additional Servers options.
To enable the Notify option:
After you have added the Notify option, you can add the Notify Additional
Servers option if you want the primary server to notify specific secondary
servers.
