Setup guide
• The EoIP protocol encapsulates Ethernet frames in GRE (IP protocol number 47) packets (just
like PPTP) and sends them to the remote side of the EoIP tunnel.
• Maximal count of EoIP tunnels is 65536.
EoIP Setup
interface eoip
Property Description
name (name; default: eoip-tunnelN) - interface name for reference
mtu (integer; default: 1500) - Maximum Transmission Unit. The default value provides maximal
compatibility
arp (disabled | enabled | proxy-arp | reply-only; default: enabled) - Address Resolution Protocol
tunnel-id (integer) - a unique tunnel identifier
remote-address - the IP address of the other side of the EoIP tunnel - must be a Wandy router
mac-address (MAC address) - MAC address of the EoIP interface. You can freely use MAC
addresses that are in the range from 00-00-5E-80-00-00 to 00-00-5E-FF-FF-FF
Notes
tunnel-id is method of identifying tunnel. There should not be tunnels with the same tunnel-id on
the same router. tunnel-id on both participant routers must be equal.
mtu should be set to 1500 to eliminate packet refragmentation inside the tunnel (that allows
transparent bridging of Ethernet-like networks, so that it would be possible to transport full-sized
Ethernet frame over the tunnel).
For EoIP interfaces you can use MAC addresses that are in the range from 00-00-5E-80-00-00 to
00-00-5E-FF-FF-FF.
Example
To add and enable an EoIP tunnel named to_mt2 to the 10.5.8.1 router, specifying tunnel-id of 1:
[admin@Wandy] interface eoip> add name=to_mt2 remote-address=10.5.8.1 \
\... tunnel-id 1
[admin@Wandy] interface eoip> print
Flags: X - disabled, R - running
0 X name="to_mt2" mtu=1500 arp=enabled remote-address=10.5.8.1 tunnel-id=1
[admin@Wandy] interface eoip> enable 0
[admin@Wandy] interface eoip> print
Flags: X - disabled, R - running
0 R name="to_mt2" mtu=1500 arp=enabled remote-address=10.5.8.1 tunnel-id=1
[admin@Wandy] interface eoip>
EoIP Application Example
Description
Let us assume we want to bridge two networks: 'Office LAN' and 'Remote LAN'. The networks are
connected to an IP network through the routers [Our_GW] and [Remote]. The IP network can be a
