this machine has two IP address assigned on interface bond0

bond0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP
     link/ether 74:e6:e2:73:e5:61 brd ff:ff:ff:ff:ff:ff
     inet 10.150.20.91/24 brd 10.150.20.55 scope global bond0
     inet 192.168.150.12/22 brd 192.168.151.255 scope global bond0:cluster
     inet6 fe80::76e6:e2ff:fe73:e561/64 scope link
        valid_lft forever preferred_lft forever

And I can ping 192.168.150.12 from this machine and from other machines 
on network
