I've created a lab to test bonding and I'm finding a strange behaviour. When I disable one the slave interfaces, ping starts to lose packets.
Can you advise what am I doing wrong?
Thanks in advance!
Bonding = bond0 (slaves = ether1,ether3) Bonding = bond0 (slaves = ether1,ether3)
ip address = 10.1.1.1/30 ip address = 10.1.1.2/30
