Hi Javier,

 

I'm having the same problem : no reply from big3d: timeout. I'm configuring GTM/LTM for 2 link ISPs, so did you fixed the problem.

 

Thank's

Hi Younes, if you have GTM is even easier to configure, but that error can come from many different issues. Check the following:

 

  1. Check that both devices are able to establish a TCP connection on port 4353 on the IP address designated as Server, so you would be able to TS Iquery errors. (You can use netstat or statistics as well to check this. You should be able to see one Green ball for each server ip address -The local GTM one and the remote GTM ip-)

     

  2. Check that you have properly configured both GTM (in case of two of course) as servers within the datacenter (I know that it seems weird but you need to indicate the GTM which GTM you have on each DC and you do so by declaring them as Server...BigIP standalone or redundant, Ip address....you know).

     

  3. Check GTM logs and of course check which kind of monitor did you apply to the ISP links? (Check the Default Gateway pool monitor).

     

I am confident that any of these will either solve it or give us some hint about where the problem is.

 

Regards and sorry for any TYPO
