5. In the Cisco Prime Network Registrar IPAM GUI, the IP Address of the Microsoft
DNS slave must be added to the
Allow transfer and Also notify lists of the INS DNS
master server. In the following example, the IP address of the MS DNS slave is
11.11.11.1.

6. Note that alternatively, the IP address of the MS DNS slave (11.11.11.1) could be
added to an Address Match List along with either the IP address of the Cisco Prime
Network Registrar IPAM DNS Listener or the name of a TSIG key which identifies
Cisco Prime Network Registrar IPAM. The named Address Match List could then be
referenced in the Allow Transfer option.
7. Push your configuration file to your DNS secondary server, using the Deployment
options from the Cisco Prime Network Registrar IPAM system.

Case 5: PeerMaster – Effective BIND-Microsoft Multi-Master DNS
The last case is another unique case where Cisco Prime Network Registrar IPAM provides
substantial value in maximizing the flexibility of DNS deployments. The PeerMaster approach
effectively provides multi-master DNS using both Microsoft AD DNS and BIND servers.
This means that updates to either the AD DNS master or the BIND DNS “master” will be
communicated to the other masters automatically.
This configuration requires use of BIND 9.2 or later. The BIND server is actually configured
This configuration requires use of BIND 9.2 or later. The BIND server is actually configured
as a slave, but with 9.2 or later, BIND supports update-forwarding. This allows updates to be
sent to the BIND slave as if it were a master, while allowing other masters to be updated
automatically. This is the most complex yet enabling configuration presented to maximize the
benefits of managing BIND and AD-integrated DNS together. Figure 7-13 illustrates this
configuration with the four update methods:
•
Static update via Cisco Prime Network Registrar IPAM
•
Static update via Windows (MMC)
•
Dynamic update to Windows DNS
