Linux - Persistent routes not working
Hello,
I'm having problems with persistent routes.
I have the route added to route-eth1.
But when I run the 'route' command to display the routes, it does not show the newly added route.
I did restart the network service. That did not help.
I also rebooted the server, but still did not help.
I'm able to add route via command line, but they are not persistent. They go away once the network service is restarted or the server is rebooted.
Any help is appreciated.
Thanks.

What is the proper way to add routes in the routing table so after a node reboot the routes will not be lost.
I understand the /etc/defaultrouter for the default router
and the <route add> command but using this command routes will be removed once the node reboots.

NAME
routes - Specifies Internet routing information to the routing tables
SYNOPSIS
/etc/routes
DESCRIPTION
Static routes can be defined in the /etc/routes file. The /etc/routes file identifies static routes that are automatically added to the
network routing tables with the /usr/sbin/route add command. The /sbin/init.d/route script contains the /usr/sbin/route add command that
is executed for each entry in the /etc/routes file when the network is restarted on the system or the system is rebooted.
The general format of an entry in the /etc/routes file is: Dest Name1 Name2
The following is a brief description of each element in an /etc/routes file entry: A keyword that indicates whether the route is to a net-
work or to a host. The two possible keywords are -net and -host. The name or address of the destination network or host. Name1 can be
either a symbolic name (as used in the /etc/hosts or /etc/networks file) or an Internet address specified in dotted-decimal format. The
name or address of the gateway host to which messages should be forwarded. Name2 can be either a symbolic name (as used in the /etc/hosts
file) or an Internet address specified in dotted-decimal format.
The routes file is a Context-Dependent Symbolic Link (CDSL) and must be maintained as such. See the System Administration manual for more
information.
EXAMPLES
To specify a route to a network through a gateway host with an entry in the /etc/routes file, enter:
-net net2 host4
This example specifies a route to a network, net2, through the gateway host4. To specify a route to a host through a gateway host
with an entry in the /etc/routes file, enter:
-host host2 host4
This example specifies a route to a host, host2, through the gateway host4. To specify a route to a default gateway host with an
entry in the /etc/routes file, enter:
default 130.9.0.5
This example specifies a route to a default gateway with an Internet address of 130.9.0.5.
FILES
Contains the /usr/sbin/routed add command.
