Configure static routes in RedHatEnterpriseLinux

In RedHatEnterpriseLinux, configure Static Routing-Linux Enterprise Application-Linux server application information. For details, see the following. Red Hat Enterprise Linux version 3:

If this is the first configuration in Red Hat Enterprise Linux, you need to create a new file to add a static route. The file name is/etc/sysconfig/network-scripts/route-ethX. X indicates the interface number of the NIC to which you want to add a static route. This file requires three domains: GATEWAY, NETMASK, and ADDRESS. Each domain must be followed by a number indicating that this domain is related to that route. The following example shows that two static routes are configured for the network interface eth0.

/Etc/sysconfig/network-scripts/route-eth0
GATEWAY0 = 10.10.0.1
NETMASK0 = 255.0.0.0
ADDRESS0 = 10.0.0.0

GATEWAY1 = 10.2.0.1
NETMASK1 = 255.255.0.0
ADDRESS1 = 192.168.0.0

After completing the above work, you need to restart the system or restart the network:

Service network restart

Red Hat Enterprise Linux version 4:
Create the configuration file/etc/sysconfig/network-scripts/route-ethX for each network interface ethX.
The content is similar:
10.0.1.0/24 via 192.168.2.4 dev eth0
10.0.4.0/24 via 192.168.2.2 dev eth0

After that, restart the network:
Service network restart
