With Network Stretching, you can have a high-availability solution. Old and traditional applications cannot perform disaster recovery resolutions on the application layer without having to make changes, network virtualization gives that edge so that is no longer the case.

Prerequisites

  • Verify that the edge has advance gateway networking and VDC network subinterface enabled on vCloud Director.

Procedure

  1. Log in to the vSphere Web Client as an administrator.
  2. Click the vCloud Director Extender plug-in.
  3. Click New Extension and fill in the requested information for source and destination.
    Note:

    A single on-premise VDC edge is connected to a single cloud provider VDC edge, if you extend a new network from the same on-premise VDC edge to another network on a different cloud-provider VDC-edge, a new edge and a trunk port group are created, the trunk port group being attached to the new edge.

  4. Click Start.

    Automatic checks are run to verify if L2 VPN gateways exist.

    Note:

    If no L2 VPN gateway is installed, hybrid cloud installs high availability enabled L2 VPN gateways in the on-premise organization environment.

    After the checks complete, a confirmation message states that the network is stretched.
