When I want to create route when gateway is from another subnet I have to execute two commands:

   route add -host 10.10.100.17 eth0

for adding gateway, and:

   route add -net 10.210.0.0/16 gw 10.10.100.17

to add a route to network using previously defined gateway

The problem is when I wan to persist this route. I am trying to do it in /etc/sysconfig/network-scripts/route-eth0

Content of file:

10.210.0.0/16 via 10.10.100.17

But I end up with error: Bringing up interface eth0: RTNETLINK answers: No such process

How can I add a host gateway ?

UPDATE:

I tried also with syntax

ADDRESS0=10.210.0.0
NETMASK0=255.255.0.0
GATEWAY0=10.10.100.17

But there is still error. Problem is with 10.7.233.17 gateway. As I mentioned before after command route add -host 10.10.100.17 eth0 it works fine, but I don't know how to add host 10.10.100.17 in /etc/sysconfig/network-scripts/route-eth0

UPDATE2: Checked with

ADDRESS0=10.10.100.17
NETMASK0=255.255.255.255
GATEWAY0=<MY_IP>

ADDRESS1=10.210.0.0
NETMASK1=255.255.0.0
GATEWAY1=10.10.100.17

But still error.

route -n after network restart produce:

Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
10.10.100.17     <MY_IP>     255.255.255.255 UGH   0      0        0 eth0

route -n after command route add -host 10.10.100.17 eth0 produce:

Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
10.10.100.17     0.0.0.0         255.255.255.255 UH    0      0        0 eth0

So i tried with 

ADDRESS0=10.10.100.17
NETMASK0=255.255.255.255
GATEWAY0=0.0.0.0

But error still exist, btw route -n after network restart produce this same output as after route add -host 10.10.100.17 eth0 command. I am totally confused...

Try the following:

ADDRESS0=10.10.10.17
NETMASK0=255.255.255.255
GATEWAY0=<your eth0 ip here>

ADDRESS1=10.210.0.0
NETMASK1=255.255.0.0
GATEWAY1=10.10.100.17
