CISCO NETWORK REGISTRAR 6.2
PRODUCT OVERVIEW
Cisco
®
Network Registrar
®
6.2 is a full-featured Domain Name System/Dynamic Host Configuration Protocol (DNS/DHCP) system that
provides scalable naming and addressing services for enterprise and service provider networks. It significantly improves the reliability of
naming and addressing services for enterprise networks. For cable providers, Cisco Network Registrar provides scalable DNS and DHCP
services for hundreds of thousands of devices and forms the basis of a DOCSIS
®
cable modem provisioning system. For telecom service
providers, it continues to play an important role in service activation for data, voice over IP (VoIP), and mobile services.
Cisco Network Registrar 6.2 includes a standards-compliant DNS server that offers the most advanced feature set in the industry, including
support for incremental zone transfers, dynamic updates, and notifications. The Cisco Network Registrar DHCP server supports DHCP failover
with redundant DHCP servers, dynamic DNS updates, DOCSIS cable modems, and integration with directory services using Lightweight
Directory Access Protocol Version 3 (LDAPv3). Moreover, tight integration with Cisco IOS
®
Software devices further elevates the value of the
Cisco Powered Network solution.
The Cisco Network Registrar scalable deployment architecture consists of several local clusters and one regional cluster. The local cluster is
deployed in the network to handle DNS and DHCP services, whereas the regional cluster is usually deployed at the data center or the network
operations center (NOC) to centrally manage the local clusters.
The regional cluster implements many IP Address Management (IPAM) features to help users reduce operational costs. With IPAM, Cisco
Network Registrar administrators can control and monitor DNS and DHCP servers from a centralized location. This capability eliminates many
manual, repetitive, and error-prone tasks configuring the local servers deployed in the network, and allows for a single point of data aggregation
and delegation.
Address-space management simplifies the task of managing address blocks and can be exercised from the regional cluster. An address block can
contain static or dynamic addresses, and can have any number of child address blocks culminating in one or more subnets. An administrator can
break an address block into small units and put the smaller blocks in a local cluster. Similarly, the administrator can also roll up address blocks
in the local cluster under their parent to provide a unified view of the address space. Instead of traversing every local cluster to gather subnet
usage and lease history information, Cisco Network Registrar administrators can achieve the same result from the regional cluster, thus making
the task of collecting usage data simple and virtually effortless. Without an automated solution, management of address blocks can be very
complex, tedious, and time-consuming.
The regional cluster manages and monitors the local clusters through its cluster management capability. Cluster management allows central
management of address space and global protocol server configuration, such as policies, client classes, and scope templates. Using the Web user
interface, the administrator at the regional cluster can add and manage a list of Cisco Network Registrar local clusters and their credentials. With
this capability, administrators can create and manage a list of local clusters using the Web user interface on the regional cluster. In addition,
administrators can centrally manage the local clusters, such as creating, pulling, and pushing VPNs, DHCP client classes, scope templates, and
policies; managing failover pairs; and handling zone distribution. Through the Web user interface, administrators can also pull subnet usage and
IP lease history data from the local clusters.
