This article shows how to bond (or aggregate) multiple ethernet interfaces into a bond0 interface.

Note: Alpine Linux v2.4 or later is required

Installation

First, install the bonding package. This will give you support for bonding in the /etc/network/interfaces file.

apk add bonding

Configuration

Edit the /etc/network/interfaces file:

auto bond0
iface bond0 inet static
	address 192.168.0.2
	netmask 255.255.255.0
	gateway 192.168.0.1
	# specify the ethernet interfaces that should be bonded
	bond-slaves eth0 eth1 eth2 eth3

The keyword is bond-slaves that will make ifup add the slaves to the bond0 interface.
