   A Virtual Private LAN Service (VPLS) is used to interconnect 
   systems across a wide-area or metropolitan-area network, making it 
   appear that they are on a private LAN.  The systems which are 
   interconnected may themselves be LAN switches.  If, however, they 
   are IP hosts or IP routers, certain simplifications to the operation 
   of the VPLS are possible.  We call this simplified type of VPLS an 
   "IP-only LAN Service" (IPLS).  In an IPLS, as in a VPLS, LAN 
   interfaces are run in promiscuous mode, and frames are forwarded 
   based on their destination MAC addresses.  However, the maintenance 
   of the MAC forwarding tables is done via signaling, rather than via 
   the MAC address learning procedures specified in [IEEE 802.1D].  
   This draft specifies the protocol extensions and procedures for 
   support of the IPLS service. 

   The original intent was to provide an alternate solution to VPLS
   for those PE routers that were not capable of learning MAC address
   through data plane. This became a non-issue with newer hardware.
   The concepts put forth by this draft are still valuable and are
   adopted in one form or other by newer work such as Ethernet VPN
   in L2VPN Working Group and possible data center applications. At
   this point, no further action is planned to update this document
   and is published simply as a historic record of the ideas.
   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",  
   document are to be interpreted as described in RFC 2119.
