[GSS and an authoritative DNS]

Hi,

i'm a newbie to GSS and was asked the following question by a customer: can you have a primary (hidden) authoritative DNS server per cisco's DNS architecture recommendations and have the GSS act as the primary DNS server for the rest of the world, while zones get transferred from the hidden authoritative DNS to the GSS?

also, is there a design guide for a DNS architecture with GSS, CSS, FWs, etc?

please advice,

c.

Re: [GSS and an authoritative DNS]

Hi Carlos,

If you wants full DNS appliance or DHCP support or GSLB for other DNS record types, order the Cisco GSS DNS license (SF-GSS-DNSLIC) plus the Cisco Network Registrar software (CNR-6.3-BASE1K is the recommended base Cisco Network Registrar software for the Cisco GSS).

The Cisco GSS DNS software license allows you to load Cisco Network Registrar software onto your Cisco GSS 4492R, which transforms the Cisco GSS 4492R into a standards-compliant DNS and DHCP appliance that offers a very advanced feature set, including support for incremental zone transfers, dynamic updates, and notification. The Cisco Network Registrar DHCP server supports DHCP Safe Failover (redundant DHCP servers), dynamic DNS updates, DOCSIS cable modems, and integration with directory services using Lightweight Directory Access Protocol Version 3 (LDAPv3).

Note:

• Cisco Network Registrar software must be acquired separately. You must load Cisco Network Registrar Release 6.3 or higher on the Cisco GSS device to get the additional DNS and DHCP capabilities

• Cisco GSS Software Release 2.0(2) or higher must be loaded on the Cisco GSS device.

Re: [GSS and an authoritative DNS]

Hi, sachinga:

i was wondering if you could provide some advice in measuring how many servers (CNR servers) are needed to fulfill a requirement. for example, say my network need to be able to handle 10000 qps. how many servers would be needed? is there a document that says how many QPS the regular CNR software (with, for example, the minimum hw requirements) is able to service?

your help would be appreciated.

thanks!

c.
