IP over Ethernet does not have this functionality, and it is not specified in the IETF when an IP over Ethernet client should consider its WAN connectivity down, unless there is a physical layer link down event. This document describes a mechanism for IP over Ethernet clients to achieve connectivity validation, similar to that of PPP over Ethernet, by using BFD Echo, or ARP and Neighbor Discovery functions.}, }
