Hi Thank you for the feedback . From one of the diagrams you linked me to it appears that the vMotion IP range ( typically VMK1 ) from VC/Site 1 must be able to talk to the vMotion IP on VC/Site2 . So that covers my question . We currently have LOCAL non routable vmotion VLANs in each Site. I will need to have this changed to either a spanned/stretched/or at least routable network .
