This document discusses bonding interfaces in Mikrotik routers. It begins with an overview of bonding and its benefits of higher throughput and failover. It then covers the different options for link monitoring and bonding modes, including active-backup, load balancing, and broadcast modes. It provides an example configuration of bonding two Ethernet interfaces together. Finally, it proposes testing the bonded bandwidth and provides references for further reading.

3. Bonding Interface Mikrotik

Bonding is a technology that allows aggregation of multiple
Ethernet-like interfaces into a single virtual link, thus getting higher
data rates and providing failover. Provided High Available and
Maximum Throughput.

4. Link Monitoring4
Link Monitoring : method to use for monitoring the link (whether it is up or down)
ARP Monitoring : ARP monitoring sends ARP
queries and uses the response as an indication
that the link is operational.
MII Monitoring : Media Independent Interface is
an abstract layer between the operating system
and the NIC which detects whether the link is
running (it performs also other functions, but in
our case this is the most important)

5. Bonding Mode
5
I802.3ad : EEE 802.3ad dynamic link aggregation. be sure that this
switch supports IEEE 802.3ad standard. Provides fault tolerance and
load balancing.

6. Active-Backup
´ active-backup : provides link backup. Only one slave can be
active at a time. Another slave becomes active only, if first one fails.
6
Backup Port Active Port

7. Balance -rr and Balance-xor
´ balance-rr : round-robin load balancing. Slaves in bonding
interface will transmit and receive data in sequential order. Provides
load balancing and fault tolerance.
´ balance-xor: This mode balances outgoing traffic across the active
ports based on the hashed protocol header information and
accepts incoming traffic from any active port.
7

8. Balance tlb
´ The outgoing traffic is distributed according to the current load.
´ Incoming traffic is not balanced
´ this mod is address-pair load balancing
8

9. Balance alb
´ Adaptive load balancing: includes balance-tlb plus receive load
balancing (rlb) for IPV4 traffic, and does not require any special
switch support.

10. Broadcast
´ Broadcast: transmits everything on all slave interfaces. This mode
provides fault tolerance.
