Why does the bonding option `mode=6` not working in `PXE` as well as in `Kickstart` installation of Red Hat Enterprise Linux 6.4?

Issue

• Need to install Red Hat Enterprise Linux 6.4 using Kickstart/PXE method. Following are the PXE kernel comandline parameters.

APPEND initrd=/path/to/initrd.img sshd=1 ip=dhcp ksdevice=bond0 ks=<path_to_ks> bond=bond0:eth0,eth1:mode=6,miimon=100

But anaconda fails to download the kickstart file and NetworkManager awaits for bringing up bond0 all the time.

• When its done with the kickstart file with the following network line, still the same issue happens.

network --onboot=yes --device bond0 --bootproto dhcp --bondopts mode=6,miimon=100 --bondslaves eth0,eth1

• Why mode=6 is not working? Is this a bug? Is there any workaround for the same?
