1. Fun with EoIP Mike Everest, DuxTel Pty Ltd

2. Ethernet over IP …not just another GRE tunnel! Transparent layer2 transport Presents as a virtual Interface to RouterOS Carries Ethernet frames Can bridge it Can route it Can firewall filter it NAT it Queue it Bond it

3. Ethernet over IP …some limitations! requires routable path (avoid NAT!) proprietary MikroTik (?) watch out for MTU on carrier network only(!) 65536 unique tunnels

4. Ethernet over IP …easy to implement! Router A remote-address (IP of Router B) tunnel-id (0 – 255) Router B remote-address (IP of Router A) tunnel-id (matches other end)

5. Example 1 Connect to Remote Hotspot

6. Example 1 Internet Gateways

7. Ethernet over IP Hotspots on Layer2 WAN

8. Example 1 HotSpots use pppoe

9. Example 1 Remote/Mobile hotspots connect using pptp

10. Example 1 Concept: create EoIP tunnel across ppp

11. Example 1 Concept: bridge local wlan to remote HS HS bridge internet wlan1 eth1 eoip wlan1 eth1 Remote Router Local Router

12. Example 1 Concept: bridge local wlan to remote HS HS bridge internet wlan1 eth1 eoip wlan1 eth1 Remote Router Local Router EoIP bridge

13. Example 1: Demo

14. Example 2 the weakest link colo cloud internet ISP LAN

15. Example 2 the pipe dream colo cloud internet ISP LAN

16. Example 2 load balanced uplinks colo cloud internet ISP LAN

17. Example 2 limited to one link per stream colo cloud internet ISP LAN

18. Example 2 EoIP to the rescue! internet LAN ISP

19. Example 2 set out the groundwork internet LAN ISP pppoe-out1 pppoe-out2

20. Example 2 lay in the tunnels internet LAN ISP

21. Example 2 force traffic path internet LAN ISP 10.10.1.1 10.10.1.2 10.100.1.2 /ip route add dst-address=10.10.1.1/32 gateway=pppoe-out1 /ip route add dst-address=10.10.1.2/32 gateway=pppoe-out2

22. Example 2 force traffic path internet LAN ISP 10.10.1.1 10.10.1.2 10.100.1.1 10.100.1.2 /int eoip add tunnel-id=1 remote=10.10.1.1 local=10.100.1.1 /int eoip add tunnel-id=2 remote=10.10.1.1 local=10.100.1.2

23. Example 2 bond them! internet LAN ISP

24. Example 2 a single virtual aggregate link! internet LAN ISP

25. Example 2 a single virtual aggregate link! internet LAN ISP

26. Example 2 combined bandwidth per stream! internet LAN ISP
