                        IP-Only LAN Service (IPLS)


   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 that 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    Media Access Control (MAC) addresses.  However, the maintenance of    the MAC forwarding tables is done via signaling, rather than via the    MAC address learning procedures specified in the IEEE's "Media Access    Control (MAC) Bridges".  This document 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 Provider Edge (PE) routers that were not capable of learning    MAC addresses through data plane.  This became a non-issue with newer    hardware.  The concepts put forth by this document 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    it is published simply as a historic record of the ideas.
