Bonding 3 nics with a fourth nic on a separate network
I have bonded three nics and that works fine however, I have configured a 4th nic for a separate network and when I bring that nic online the bond no longer responds. How do I make the Bond the first in the boot order so the 4th nic does not interfere?
Thanks,

When RHEL runs through the ifcfg files, if you've specified more than one file with a gateway, the default route add operation will be executed for each gateway declaration. Since the ifcfg files get processed serially, the default route will get set to whatever is declared in the last gateway-containing file.
You can typically get past this by only declaring a gateway in only one of the ifcfg files or declaring a gateway-dev in one of the higher-order network config files.
