Bonding EoIP tunnels over two wireless links

This is an example of aggregating multiple network interfaces into a single pipe. In particular, it is shown how to aggregate multiple virtual (EoIP) interfaces to get maximum throughput (MT) with emphasis on availability.

Network Diagram

Two routers R1 and R2 are interconnected via multihop wireless links. Wireless interfaces on both sides have assigned IP addresses.

Getting started

Bonding could be used only on OSI layer 2 (Ethernet level) connections. Thus we need to create EoIP interfaces on each of the wireless links. This is done as follows:

  • on router R1:
[admin@MikroTik] > /interface eoip add remote-address=10.0.1.1/24 tunnel-id=1
[admin@MikroTik] > /interface eoip add remote-address=10.0.2.1/24 tunnel-id=2
  • and on router R2
[admin@MikroTik] > /interface eoip add remote-address=10.1.1.1/24 tunnel-id=1
[admin@MikroTik] > /interface eoip add remote-address=10.2.2.1/24 tunnel-id=2

The second step is to add bonding interface and specify EoIP interfaces as slaves:

  • R1:
[admin@MikroTik] > / interface bonding add slaves=eoip-tunnel1,eoip-tunnel2 mode=balance-rr
  • R2
[admin@MikroTik] > / interface bonding add slaves=eoip-tunnel1,eoip-tunnel2 mode=balance-rr

The last step is to add IP addresses to the bonding interfaces:

  • R1:
[admin@MikroTik] > / ip address add address 192.168.0.1/24 interface=bonding1
  • R2
[admin@MikroTik] > / ip address add address 192.168.0.2/24 interface=bonding1

Test the configuration

Now two routers are able to reach each other using addresses from the 192.168.0.0/24 network. To verify bonding interface functionality, do the following:

  • R1:
[admin@MikroTik] > /interface monitor-traffic eoip-tunnel1,eoip-tunnel2
  • R2
[admin@MikroTik] > /tool bandwidth-test 192.168.0.1 direction=transmit

You should see that traffic is distributed equally across both EoIP interfaces:

Link Monitoring

It is easy to notice that with the configuration above as soon as any of individual link fails, the bonding interface throughput collapses. That's because no link monitoring is performed, consequently, the bonding driver is unaware of problems with the underlying links. Enabling link monitoring is a must in most bonding configurations. To enable ARP link monitoring, do the following:

  • R1:
[admin@MikroTik] > / interface bonding set bonding1 link-monitoring=arp arp-ip-targets=192.168.0.2
  • R2
[admin@MikroTik] > / interface bonding set bonding1 link-monitoring=arp arp-ip-targets=192.168.0.1
