Hello,
I implemented a network with the following topology:

Later, I set up the bond in ‘active backup’ mode using ARP.
However, 15% of the packets are lost because it is constantly switching between ether1 and ether2.
How to solve?

Configuration:
[admin@R1] /interface bonding> print

0 R name="bonding1"
mtu=1500
mac-address=6C:3B:6B:FE:6D:08
