First you need to create a bond interface with the required type of balancing. I’m using 802.3ad

If your machine has the ifenslave package, then you are very lucky. Through managers (/etc/network/interfaces or systemd-networkd or something else) it will start without any problems, if you do not forget about loading the module into the kernel.

In my case, this package is not there, and you need a network to install it

We do this using the classic method - by hand)

ip link add bond0 type bond0 mode 802.3ad

ip link set down dev eth0
ip link set eth0 master bond0
ip link set up dev eth0

ip link set down dev eth1
ip link set eth0 master bond0
ip link set up dev eth1

ip link set up dev bond0

Если ip link add bond0 doesn’t work, you can do it through the kernel

modprobe bonding mode=4

Well, then you can put the required address on the interface.
