Redhat 6.5, loss of default gateway.

Dear friends
I use RedHat 6.5, which sets the gateway in the configuration file / etc / sysconfig / network as GATEWAY = 192.168.1.26, and the gateway in the configuration file / etc / sysconfig / network-scripts / ifcfg-eth11 as GATEWAY = 192.168.1.256. The two gateways are different. After restarting the service, the default gateway is lost and the external network cannot be accessed. Do you know why?
The configuration file information is as follows：

Code:

/ etc / sysconfig / network
NETWORKING=yes
HOSTNAME=localhost.localdomain
GATEWAY=192.168.1.26

/ etc / sysconfig / network-scripts / ifcfg-eth11
TYPE=Ethernet
DEVICE=eth11
BOOTPROTO=static
IPADDR=192.168.1.10
NETMASK=255.255.255.0
GATEWAY=192.168.1.254
METRIC=104
ONBOOT=yes
NAME=eth11

Thanks in advance....
Regards,
Tanpeng

       used to map the SSID name to an iface stanza.

CONFIGURATION

       A sample /etc/network/interfaces may look like this:

	  mapping hotplug
	    script /etc/network/essidscan
	    map SSIDONE  wlan-work
