Hello Scott,

 

Yes I am sure that GTM is resolving the wideip to the DR VIP. One thing we noticed yesterday was that the primary VIP is continously flapping and going RED . When its going RED , thats when the traffic is going to DR VIP.

 

On LTM teh primary VIp , pool members are green when it shows red on GTM , so not sure why GTM is marking it down. Below I have pasted few logs:

Main thing to notice here is that GTM logs a message : could not find monitor object for primary VIP. I was checking one of sol article and it says only if GTM devices in sync are in diff software versions then GTm will throw such error. But our devices are running on same version and HF.
