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 =, and the gateway in the configuration file / etc / sysconfig / network-scripts / ifcfg-eth11 as GATEWAY = 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:

/ etc / sysconfig / network

/ etc / sysconfig / network-scripts / ifcfg-eth11

Thanks in advance....

Do two different configurations of gateways necessarily result in the loss of default gateways? When the information of two configuration files is inconsistent, the / etc / sysconfig / network-scripts / ifcfg-eth11 configuration information should prevail,no loss of default gateway. But my default gateway is missing.

Is the gateway really lost? Check with
netstat -nr | grep -w UG

I checked, No default gateway,

Strange, I would expect that one of the two GATEWAY would supersede. You should have a RedHat contract, then contact RedHat support to clarify if this is a bug; almost certainly they will tell you to update your OS!

To resolve the conflict, with a text editor (lvim or nano or gedit or ...) you must either delete the GATEWAY line in the /etc/sysconfig/network (common to all ifcfg-X interface files) or the GATEWAY in the ifcfg-eth11!
Alternative: delete with sed, for example:
sed -i '/^GATEWAY/d' /etc/sysconfig/network

Maybe you better use the system-config-network-tui (A correction: if not present you install it with yum install system-config-network-tui).
