Abstract 
    
   A Virtual Private LAN Service (VPLS) [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.
