Ethernet-within-IP Encapsulation - IP Protocol
This page provides IP protocol information on the Ethernet-within-IP Encapsulation IP protocol (ETHERIP) detected by the Netify DPI engine. Please see the IP protocol catalog for information on other IP protocols.
ETHERIP is Ethernet-within-IP Encapsulation, a simple tunneling protocol that wraps whole Ethernet frames inside IP packets to bridge remote LANs.

ETHERIP was standardized in RFC 3378 (2002) and remains implemented in some operating systems and network devices for Layer 2 tunneling, though less common than GRE/VXLAN.
IP Protocol Network Policy
ETHERIP is used to bridge remote Ethernet LAN segments over IP tunnels; allow only on gateways specifically configured for Layer 2 tunneling, which is uncommon outside legacy setups.
