Route.
Route keeps the data about the routing table. Main use of the Route is to have the static routes to network using an interface which has been configured by ifconfig command.
For adding the route to the network follow below steps
A. Check the current routing information.
- # route -n
- Kernel IP routing table
- Destination Gateway Genmask Flags Metric Ref Use Iface
- 10.41.42.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
- 10.41.41.0 10.41.42.8 255.255.255.0 UG 0 0 0 eth0
- 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0
- 0.0.0.0 10.41.42.1 0.0.0.0 UG 0 0
B.To add a route refer to the command below.
"route add -net 10.41.41.0 netmask 255.255.255.0 gw 10.41.42.8"
C. To delete a route refer to the command below.
"route del -net 10.41.41.0 netmask 255.255.255.0 gw 10.41.42.8"
D.To make the rounting information persistent after reboot.
The routing information above is not persistent across reboots. After a reboot, the routing information will be lost and you need to add them in again. To make the routing information persistent, add the “route add” line as seen above into the /etc/rc.local file.
- #!/bin/sh
- #
- # This script will be executed *after* all the other init scripts.
- # You can put your own initialization stuff in here if you don’t
- # want to do the full Sys V style init stuff.
- touch /var/lock/subsys/local
- route add -net 10.41.41.0 netmask 255.255.255.0 gw 10.41.42.8
