When I add the same virtual subnet ID to two virtual network adapters they can't ping each other RRS feed

  • Question

  • I am running Windows Server 2012 R2 with Hyper-v role installed. 

    It is nested virtualization with VMware Workstation

    VM1 on host 1

    VM2 on host 1

    Added VSID to both VM network adapters: 4666

    Windows firewall on both VMs allows ping

    When the VM VSID is set to 0 they can ping each other. 

    When the VM VSID is set to another number they cannot reach each other. 

    The Hyper-v Virtual Switch is of type external

    It also has multiple ManagementOS Virtual adapters attached to it with different VLAN numbers. 

    I think NVGRE is already enabled in the switch in R2, correct?

    The goal is to get these two VMs talking to each other via NVGRE

    What am I missing?
