GSS Setup Information

Need to know to what entries should go in the Public DNS server for the domail/url x.y.com so that the request from clients or DNS-Proxy for the domain x.y.com is responded by the GSS-P or GSS-S. Secondly which GSS will respond to the client/DNS-P response. Thanks

Re: GSS Setup Information

Not sure what you have as a dns server. But in essence you would make the 2 GSS's authoritative for the x.y.com sub domain. If we take a Bind server as an example you have 2 otions first would be direct delegation of A records to the GSS , in this example I am making GSS authoritative for www.cisco.com

$TTL 3h

cisco.com. IN SOA nameserver1.cisco.com. adminemail.cisco.com. (

   2003070801              ; Serial

   3h      ; Refresh  after 3 hours

   1h      ; Retry after 1 hour

   1w      ; Expire after 1 week

   1h )    ; Negative caching TTL of 1 hour

;

; Name servers

;

cisco.com. IN NS nameserver1.cisco.com.

www.cisco.com. IN NS gss1.cisco.com.  ß NS record for www.cisco.com  via GSS1

www.cisco.com. IN NS gss2.cisco.com.  ß NS record for www.cisco.com via GSS2

;

; Addresses

;

localhost.cisco.com.       IN A 127.0.0.1

nameserver1.cisco.com.     IN A 10.10.10.1

gss1.cisco.com.            IN A 10.1.1.254  ß A record for GSS1

gss2.cisco.com.            IN A 10.1.2.254  ß A record for GSS2

The other option is to delegate the subdomain to the GSS's using CNAME

$TTL 3h

cisco.com. IN SOA nameserver1.cisco.com. adminemail.cisco.com. (

   2003070801              ; Serial

   3h      ; Refresh  after 3 hours

   1h      ; Retry after 1 hour

   1w      ; Expire after 1 week

   1h )    ; Negative caching TTL of 1 hour

; Name servers

;

cisco.com. IN NS nameserver1.cisco.com.

gslb.cisco.com.    IN NS gss1.gslb.cisco.com.  ß delegates authority for gslb.cisco.com via GSS1

gslb.cisco.com .   IN NS gss2.gslb.cisco.com.  ß delegates authority for gslb.cisco.com via GSS2

gss2.gslb.cisco.com.               IN A 10.1.2.254  ß A record for GSS2

; Aliases

www.cisco.com.     IN CNAME www.gslb.cisco.com.  ß client can use either name

attaching a somewaht dated best practices document however the points remain valid.

Re: GSS Setup Information

so to recap, i need to add a NS record for the subdomain and those NS records should point to the GSS-P and GSS-S. the name server has GSS-P and GSS-S A records.

Please correct me if i understood correctly
