	RouterOS v3 Configuration and User Guide

name (name) - descriptive name of bonding interface

primary (name; default: none) - Interface is used as primary output media. If primary interface fails, only then others slaves will be used. This value works only with mode=active-backup

slaves (name) - at least two ethernet-like interfaces separated by a comma, which will be used for bonding

up-delay(time; default: 00:00:00) - if a link has been brought up, bonding interface is disabled for up- delay time and after this time it is enabled. Value should be a multiple of mii-interval

Application Examples

Bonding two EoIP tunnels

Assume you need to configure the AT-WR4500 router for the following network setup, where you have two offices with 2 ISP for each. You want combine links for getting double speed and provide failover:

	Internet ISP2
	Eoip-tunnel 1
[Office2]		[Office1]
	10.0.0.1
Local Net	bonding1	Local net

Eoip-tunnel 2

Internet ISP1

Figure 21: Bonding two EoIP tunnels

We are assuming that connections to Internet through two ISP are configured for both routers. Office1 configuration:
