      "This module contains a collection of YANG definitions for
     supporting the Broadband Forum requirements on layer 2 forwarding
     as applicable to access network equipment. As such, this module
     is specific to access network equipment (e.g., BBF-specified
     Access Nodes and FTTdp DPUs).

     More specific this module contains a collection of YANG
     definitions for managing shared forwarding databases.
