route -n -v
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
10.0.40.0       0.0.0.0         255.255.255.0   U     0      0        0 eth0
0.0.0.0         10.0.40.1       0.0.0.0         UG    0      0        0 eth0

route add -v a.b.c.d  gw 10.0.40.17

route -n -v
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
198.35.28.125   10.0.40.17      255.255.255.255 UGH   0      0        0 eth0
10.0.40.0       0.0.0.0         255.255.255.0   U     0      0        0 eth0
0.0.0.0         10.0.40.1       0.0.0.0         UG    0      0        0 eth0

if we need to delete the static route, here is the command:

delete static route to destination ip a.b.c.d
route del a.b.c.d

the ‘route add‘ command is obsolete, the new command is ‘ip route add‘

ip route add a.b.c.d via 10.0.40.17 dev eth0  # add a static route
ip route del   a.b.c.d            # delete a static route

the ‘ip route add‘ command and ‘route add‘ command are temporary, meaning the entries will be gone after reboot. to make it permanent.   Edit the file /etc/sysconfig/entwork-scripts/route-eth0

cat /etc/sysconfig/network-scripts/route-eth0
a.b.c.d via 10.0.40.17 dev eth0

• to manually reload the route-eth0 file, simply restart the network service
  service network restart
