# eoip: a Linux implementation of MikroTik EoIP tunnelling

> eoip implements MikroTik-compatible Ethernet-over-IP tunnelling in Linux kernel modules with a user-space management utility. The author says development used sniffed datagrams; the README documents the GRE-like packet format, tunnel configuration and keepalive behaviour for IPv4 and IPv6 variants.
