If you are not using GSS as primary DNS server for abc.com and just want to delegate xyz.abc.com then

On your primary DNS server (authoritative for abc.com) delegate the fully qualified domain name www.abc.com to the GSS and make these GSSs authoritative for this domain.

Following changes will be needed on the primary dns server

www.abc.com. IN NS gss1.abc.com. <-- NS record for www.abc.com via GSS

gss1.abc.com. IN A a.b.c.d <-- A record for GSS

If there is already a DNS server authoritative for abc.com then it should already have NS record for abc.com.

In order to delegate http://www.abc.com to two GSSs, you need two NS records on Primary DNS server and A records for the two GSSs

http://www.abc.com. IN NS gss01.abc.com. <-- NS record for http://www.abc.com via GSS01

http://www.abc.com. IN NS gss02.abc.com. <-- NS record for http://www.abc.com via GSS02

gss01.abc.com. IN A 1.1.1.1 <-- A record for GSS01

gss02.abc.com. IN A 2.2.2.2 <-- A record for GSS02

Typical flow is as follows

1. Client will hit their DNS servers (configured on their machines as primary/backup dns server).

2. "Client's DNS server" will query "DNS server authoritative for abc.com" for www.abc.com.

3. "DNS server authoritative for abc.com" will ask "client's DNS server" to query "GSS - Authoritative for www.abc.com"

4. "Client's DNS server" will query GSS for www.abc.com.

5. GSS will send the ip add of www.abc.com (which should be configured on ACE as VIP).

6. "Client's DNS server" will handover this VIP to client

7. Client will hit the VIP configured on ACE (for application www.abc.com).

Hi,

This is the final script which i am going to put in my dns server

www.abc.com. IN NS gss01.abc.com. <-- NS record for http://www.abc.com via GSS01

www.abc.com. IN NS gss02.abc.com. <-- NS record for http://www.abc.com via GSS02

gss01.abc.com. IN A 1.1.1.1 <-- A record for GSS01

gss02.abc.com. IN A 2.2.2.2 <-- A record for GSS02

xyz.abc.com. IN NS gss1.abc.com. <-- NS record for xyz.abc.com via GSS

is it ok...

Do you want the two GSSs (gss01 & gss02) to abe authoritative for both www.abc.com & xyz.abc.com?

If yes then you need follwoing lines

xyz.abc.com. IN NS gss01.abc.com.

xyz.abc.com. IN NS gss02.abc.com.

www.abc.com. IN NS gss01.abc.com.

www.abc.com. IN NS gss02.abc.com.

gss01.abc.com. IN A 1.1.1.1

gss02.abc.com. IN A 2.2.2.2

Hi,

no.. in between one more NS server is there which will be forwarder for these GSS..

GSS is responsible ofr A record only

Sateesh

We are moving in circle with this thread.

I think you need to grasp some bind knowledge before you proceed. I would recommend reading some basic DNS theory.

If you are not sure what you are doing then there is a very good possibility of messing up your DNS server.

I am sure one or two hour reading on DNS will make you understand how to introduce GSS in your existing DNS infrastructure.
