F5 GTM for Multi domain DNS ( if there is more then 1 Domain in DNS servers )

I have a requirement where GTM has to provide GSLB solution for 3 different domain which are hosted on Infoblox DNS server like below.

 

domain1.com

 

domain2.com domain3.com

 

Subdomain will be created on the GTM for all these domain and delegation will be configured on Infoblox DNS server.

 

BIG-IP DNS

    Hi Manish,

     

    Sounds fine to me.

     

    So on the Infoblox witin each zone file, you'll have something like.

     

    wip.domain1.com IN NS gtm addresses

     

    wip.domain2.com IN NS gtm addresses

     

    wip.domain3.com IN NS gtm addresses

     

    Then when you want to Load balance an address with GTM add in a CNAME on Infoblox.

     

    www.domain1.com IN CNAME www.wip.domain1.com

     

    etc.

     

    The DNS resolution request then gets sent to GTM for intelligent resolution via a WideIP.
