    Hi Dmitry,
    is there a notion of ‘vrf’ on DLR control VM so that this management interface gets separated from VXLAN routing plane?
    And one more question, if giving IP to management interface is optional why isn’t the same true for assigning it to a port group?

      Hi Michael,

      There’s no VRF support in DLR at this point; management or otherwise.

      I do not know the exact reason why connecting Management interface is mandatory. It is not used by NSX itself, since all Edge appliances – Control VMs and ESGs – are managed via VMCI channel, or in some rare cases via VIX, which doesn’t need any vNICs connected.

    Hi Dmitry,
    What if I ‘m interested in opening up SSH to the DLR Controller w/o host-jumping ? I.e. it’s conceivable that my management station sit sin another subnet. Is there a plan to support this going forward or could we SSH plainly to one of the vxlan based interfaces insofar these prefixes are reachable from the outside.

      Hello,

      You can’t connect to DLR Control VM on any of DLR’s VXLAN LIFs, because the IP addresses associated with LIFs are distributed and served by ESXi hosts, not the DLR Control VM.

      You can only SSH into DLR Control VM on the “Protocol IP”, as described in this post.

      Also starting with NSX 6.2, you can execute many of the Edge CLI commands directly from the centralised CLI, with no need to SSH into DLR Control VM. Instead, SSH into your NSX Manager and run these commands from there.
