8.1EoIP

8.1.1 General Information

Summary

Ethernet over IP (EoIP) Tunneling is a RouterOS protocol that creates an Ethernet tunnel between two routers on top of an IP connection. The EoIP interface appears as an Ethernet interface. When the bridging function of the router is enabled, all Ethernet traffic (all Ethernet protocols) will be bridged just as if there where a physical Ethernet interface and cable between the two routers (with bridging enabled). This protocol makes multiple network schemes possible.

Network setups with EoIP interfaces:

•Possibility to bridge LANs over the Internet

•Possibility to bridge LANs over encrypted tunnels

•Possibility to bridge LANs over 802.11b 'ad-hoc' wireless networks

Quick Setup Guide

To make an EoIP tunnel between 2 routers which have IP addresses 10.5.8.1 and 10.1.0.1: On router with IP address 10.5.8.1, add an EoIP interface and set its MAC address:

/interface eoip add remote-address=10.1.0.1 tunnel-id=1 mac-address=00-00-5E-80-00-01 \ \... disabled=no

On router with IP address 10.1.0.1, add an EoIP interface and set its MAC address:

/interface eoip add remote-address=10.5.8.1 tunnel-id=1 mac-address=00-00-5E-80-00-02 \ \... disabled=no

Now you can add IP addresses to the created EoIP interfaces from the same subnet.

Description

EoIP interface may be configured between two routers that have active IP level connection. The EoIP tunnel may run over an IPIP tunnel, a PPTP 128bit encrypted tunnel, a PPPoE connection, or any other connection that transports IP.

Specific Properties:

Each EoIP tunnel interface can connect with one remote router which has a corresponding interface configured with the same 'Tunnel ID'.
