IP Point to Point Ethernet subnet model
Ole Trøan · 2000
Ethernet topology is no longer a shared medium. It is a long time since Ethernet has been a thick yellow cable snaking its way from station to station. Ethernet is now effectively deployed in a hub and spoke topology. With a point to point link between a host and the network device. This memo describes a set of simplications for how to run IP over such links, where the physical topology is exposed in the network layer topology.
