"/etc/sysconfig/network-scripts/route-<interface-name>
Contains lines that specify additional routes that should be added
when the
associated interface is brought up.
The files are processed by the ifup-routes script and uses the
/sbin/ipcalc
utility for all network masks and numbers. Routes are specified using the
syntax:
ADDRESSn=<network>
NETMASKn=<network/prefix mask>
GATEWAYn=<next-hop router/gateway IP address>
The "n" can be any integer number, but is expected to be monotonically
increasing and counting starts from 0. For example:
ADDRESS0=192.168.2.0
NETMASK0=255.255.255.0
GATEWAY0=192.168.1.1
adds a network route to the 192.168.2.0 network via the gateway at
192.168.1.1. Since you must already have a route to the network of the
gateway, there is no need to specify a device.
Note: The ifup-routes script also supports an older syntax designed to be
used directly as an argument to "/sbin/ip route add". This syntax is
deprecated, but if no "ADDRESSn" lines are found the following will still
work:
192.168.2.0/24 dev ppp0
adds a network route to the 192.168.2.0 network through ppp0."
