How do I create persistent static routes in Red Hat Enterprise Linux 4?
Resolution:

To add a persistent static route, create the following file for each ethX device.

/etc/sysconfig/network-scripts/route-ethX

Every entry or a route has three lines as follows:

GATEWAY<N>=xxx.xxx.xxx.xxx
NETMASK<N>=yyy.yyy.yyy.yyy
ADDRESS<N>=zzz.zzz.zzz.zzz

As the names implies, they are the gateway IP, Netmask and the IP/Network Address.

Note the <N> next to each of the three entities. This number defines the route entry number and should be the same on all the entities.

Example:


GATEWAY0=192.168.1.1
NETMASK0=255.255.255.0
ADDRESS0=10.10.10.0

GATEWAY1=192.168.1.1
NETMASK1=255.255.255.0
ADDRESS1=20.20.20.2

Restart the network.

To dynamically add a route execute the following command: 

# ip route add <Net/IP>/Netmask> via <Gateway IP> dev <InterfaceX>

Example: 

# ip route add 10.10.10.0/24 via 192.168.1.1 dev eth0

Confirm with following command:

# ip route show
