Hello, hope you are doing fine
Since you can't deploy all the virtual machines on the stretched cluster (which would've been the easiest configuration)
I'd suggest the following
Create a DLR CVM on Site A cluster and a DLR CVM for Site B each of those connected to it's ESG.
Please consider enabling NSX HA on both Edge Services Gateway and CVM DLR and keeping anti affinity rules so both vms are always separated.:
Okay, that makes total sense! I was heading that way. Thanks!
