GTM and Wide IPs

I am new for GTM

 

GTM and Wide IPs

 

I have UNIX server which is authoritative for the top-level domain, Example.com

 

have 2 GTM boxes and made NS for wip.example.com 2 GTM was assinged in unix server as NS for wip.example.com and sub domains

 

now i want to have new DNS record test.Example.com, which is hosted in 2 LTM and both LTM mapped with 2 GTM

 

so i want to do changes for test.Example.com in UNIX server

 

and in GTM want to create WIDE IP and A recrods for 2 locations

 

i have east LTM and west LTM , so two VIP need map in Wide IP

 

My Plan:

 

Create CNAME in Unix server test.exmaple.com to test.wip.exmaple.com So request will forward to GTM boxes, I guess

 

IN GTM i creat wide IP forward.wip.exmaple.com and has two servers as mentioned below

 

forward.east.wip.exmaple.com forward.west.wip.exmaple.com

 

In zone runner

 

under wip.example.com

 

creat a records for LTM IP

 

forward.east.wip.exmaple.com IP1 A forward.west.wip.exmaple.com IP2 A

 

I need steps if any missing or corrections

 

application delivery
BIG-IP DNS
devops
LTM

    You should probably send your first text.example.com CNAME forward.wip.example.com in this case, or you could change your WIP to test.wip.example.com.

    You do not need to do anything in Zone runner.

     

    Once your GTM and LTM are communicating over iQuery:

     

    1. On the GTM, add the new Virtual Servers under their respective LTM Server Objects.
    2. On the GTM, build a pool that includes these two LTM VIP IPs.
    3. On the GTM, build the WideIP using the pool and your new FQDN, test.wip.exmaple.com.
    4. Test the resolution by using dig/nslookup against the GTM Listener, for test.wip.exmaple.com.
    5. If all is good, put in CNAME.

    One other thing, you will need A records on the DNS servers for the GTMs, to support the NS records.

     

    Good Luck!
