On CentOs-6 you can set the default route using
GATEWAY=aaa.bbb.ccc.ddd either in /etc/sysconfig/network or
/etc/sysconfig/network-scripts/ifcfg-X where X is the network
interface that you wish to use for default routing, usually eth0.
Setting the GATEWAY value in the ifcfg-X file puts it in a place that
you are likely to see far more often than /etc/sysconfig/network so
the ifcfg-X file is where I usually place it.
