RouterOS v3 Configuration and User Guide
Configure the EoIP tunnel by adding the eoip tunnel interfaces at both routers. Use the ip addresses of
the pptp tunnel interfaces when specifying the argument values for the EoIP tunnel:
[admin@Our_GW] interface eoip> add name="eoip-remote" tunnel-id=0 \
\... remote-address=10.0.0.2
[admin@Our_GW] interface eoip> enable eoip-remote
[admin@Our_GW] interface eoip> print
Flags: X - disabled, R - running
0 name=eoip-remote mtu=1500 arp=enabled remote-address=10.0.0.2 tunnel-id=0
[admin@Our_GW] interface eoip>
[admin@Remote] interface eoip> add name="eoip" tunnel-id=0 \
\... remote-address=10.0.0.1
[admin@Remote] interface eoip> enable eoip-main
[admin@Remote] interface eoip> print
Flags: X - disabled, R - running
0 name=eoip mtu=1500 arp=enabled remote-address=10.0.0.1 tunnel-id=0
[Remote] interface eoip>
Enable bridging between the EoIP and Ethernet interfaces on both routers.
On the Our_GW:
[admin@Our_GW] interface bridge> add
[admin@Our_GW] interface bridge> print
Flags: X - disabled, R - running
0 R name="bridge1" mtu=1500 arp=enabled mac-address=00:00:00:00:00:00
protocol-mode=none priority=0x8000 auto-mac=yes
admin-mac=00:00:00:00:00:00 max-message-age=20s forward-delay=15s
transmit-hold-count=6 ageing-time=5m
[admin@Our_GW] interface bridge> port add bridge=bridge1 interface=eoip-remote
[admin@Our_GW] interface bridge> port add bridge=bridge1 interface=ether1
[admin@Our_GW] interface bridge> port print
Flags: X - disabled, I - inactive, D - dynamic
# INTERFACE BRIDGE PRIORITY PATH-COST
0 eoip-remote bridge1 128 10
1 ether1 bridge1 128 10
[admin@Our_GW] interface bridge>
And the same for the Remote:
[admin@Remote] interface bridge> add
[admin@Remote] interface bridge> print
Flags: X - disabled, R - running
0 R name="bridge1" mtu=1500 arp=enabled mac-address=00:00:00:00:00:00 stp=no

garbage-collection-interval=4s hello-time=2s max-message-age=20s
[admin@Remote] interface bridge> add bridge=bridge1 interface=ether1
[admin@Remote] interface bridge> add bridge=bridge1 interface=eoip-main
[admin@Remote] interface bridge> port print
Flags: X - disabled, I - inactive, D - dynamic
# INTERFACE BRIDGE PRIORITY PATH-COST
0 ether1 bridge1 128 10
1 eoip-main bridge1 128 10
[admin@Remote] interface bridge> port print
Addresses from the same network can be used both in the Office LAN and in the Remote LAN.
8.1.4 Troubleshooting
Description
The routers can ping each other but EoIP tunnel does not seem to work!
Check the MAC addresses of the EoIP interfaces - they should not be the same!
