Build your primary GSSM

create keepalive type, answer dns-list and finaly dns rule. follow Configuration guide of GSS,

finally enable gssm on standby and sync it with primary.

if you have any specific question please let me know.

Thanks Gaurav for your reply.

Kinldy clarify below queries also.

1. If any option is available for doing the link loadbalancing through GSS?

2. If my application is not URL based ( There is no DNS using and we are directly accessing VIP like http://172.16.1.10 ). Suggest me how can we achive the GSLB for the same?

Regards,

Ranjith

The GSS hands out responses to DNS queries it recieves. If your client is not using DNS to resolve the name to a IP address then the GSS will not come into play.

Answering to your first point of Link Loadbalancers, yes you can deploy your GSS for Link Load balancing but only for incoming requests [not for requests originated from your site]. Althoug I have configured this for one my site, but not sure whether its operable or not

This can be achived by using source list feature of GSS and source NAT on internet routers.
