hey guys I read this article about bonding on Centos http://www.howtoforge.com/network_card_bonding_centos I've already configured bonding but I found one server where worked that was previously confiugured by someone else and I found this it is using bond0 and bond0:0 when you run a ifconfig and when you run ip appr show it says bond0 global bond bond0:0 secondary global bond other thing bond0 has its own IP and bond0:0 has its own IP and they are different. First what is that for? Second how can I configure that(primary and secondary bonds) in another linux server? thanks a lot
