    abstract =  {This document describes EtherIP, an early tunneling protocol, to provide informational and historical context for the assignment of IP protocol 97. EtherIP tunnels Ethernet and IEEE 802.3 media access control frames in IP datagrams so that non-IP traffic can traverse an IP internet. The protocol is very lightweight, and it does not provide protection against infinite loops.},
