This document describes a mechanism to ensure layer-2 separation of
Local Area Network (LAN) stations accessing an IPv4 gateway over a
bridged Ethernet segment.

The mechanism - called "MAC-Forced Forwarding" - implements an Address
Resolution Protocol (ARP) proxy function that prohibits Ethernet Media
Access Control (MAC) address resolution between hosts located within the 
same IPv4 subnet but at different customer premises, and in effect 
directs all upstream traffic to an IPv4 gateway.  The IPv4 gateway 
provides IP-layer connectivity between these same hosts.  This memo
