GTM

Hi All,

 

I am getting two IPs instead of one when i am doing nslookup of one application. Ex :-

 

abc.company.net Server: qwe.company.net Address: 10.22.46.80

 

Name: wide ip name Addresses: 10.95.67.98 10.95.21.98 Aliases: abc.company.net

 

GTM Conf :-

 

LB Pref Method :- Global Availability Alternate :- Round Robin Fallback :- Return to DNS

 

Please help me in resolving this issue

 

Regards, ShashankS

    Can you share the status of the pool member Virtual Servers you have assigned to the Wide IP?

    The default if all pool members is to fall back (

    Return to DNS
    ) to the internal BIND DNS which will reply with multiple records if you have multiple pool member Virtual Servers configured.

    You can change this behavior by changing the secondary and/or fall back methods to 

    Fallback IP
    and setting the IP or 
    None
    to not give any reply at all.
