A Virtual Private LAN Service (VPLS) [VPLS] is used to interconnect systems
across a wide-area or metropolitan-area network, making it appear to those
systems as if they are interconnected on a private LAN. The systems which
are interconnected in this way may themselves be LAN switches. If, however,
the interconnected systems are NOT LAN switches, but rather are IP hosts or
IP routers, certain simplifications are possible. We call this simplified
type of virtual private LAN service an ?Ip-only LAN Service? (IPLS). In
IPLS, as in VPLS, LAN interfaces are run in promiscuous mode, and frames
are forwarded based on their MAC Destination Addresses. However, the
maintenance of the MAC forwarding tables is done via signaling, rather than
via the ?MAC Address Learning? procedures of IEEE 802.1D. Further, Address
Resolution Protocol (ARP) messages are proxied, rather than being carried
transparently. This draft specifies the protocols and procedures for
support of the IPLS service.
