1.2 Major Functions

As part of the standard installation, Cisco Prime Network
Registrar IPAM already provides facilities for DHCP Failover

and Secondary DNS server configuration. These facilities
ensure continuous operation of these critical network services.

During a DR event in which the Cisco Prime Network
Registrar IPAM Executive is affected, the DHCP/DNS

services continue to run autonomously, so end clients will
continue to operate. However, if the Executive is unavailable,

then configuration changes for DHCP/DNS cannot be made.
To address this need, the Cisco Prime Network Registrar

IPAM Executive can be configured for redundancy using the
DR guidelines and scripts described herein.
