Iquery Communication

Hi Forum,

 

I am just trying to do a bit of studying for the 302 exam and came across this statement of f5.com

 

"iQuery communications only occur across the same VLAN; in other words, if two systems reside on different VLANs, they cannot communicate through iQuery."

 

If I have two GTMs, one is London and one in New York, how can they be on the same VLAN, I would run L2 between the sites but it is unlikely this would be the case.

    Sounds like legacy documentation to me. We have GTMs in multiple locations that route to each other over a WAN, and iQuery works just fine.

    Yeah. If this is a true/false answer, then the answer is false. iQuery (big3d comms) works fine over the WAN...

     

    It's just another TCP connection at the network level...
