VDP manages the association between a VSI and a station-facing bridge port (SBP) on a bridge.
VDP uses the Edge Control Protocol (ECP) to carry VDP TLVs. A VDP TLV comprises the VSIID, VSI
type, and VSI version.
When a station creates a VM, it sends a VDP pre-associate, pre-associate with resource
reservation, or associate packet to the bridge. The bridge sends the request to a VSI manager. The
VSI manager notifies the bridge to create a VSI interface and apply policies.
When a station shuts down a VM, it sends a VDP de-associate packet to the bridge. The bridge
sends the request to the VSI manager. The VSI manager notifies the bridge to delete the VSI
interface.
