Routing in Linux


Basic Linux routing
Add a route to a network
#route add -net network/mask gw default-gateway
Example
#route add -net 10.10.10.0/24 gw 192.168.0.1
Adding default gateway
#route add default gw default-gateway
Example #route add default gw 192.168.0.1
Adding a route to specific host
#route add -host host-name gw default-gateway
Example:
 #rotue add -host 2.34.5.6 gw 192.168.0.1
Deleting route to a network
#route del -network network/subnet default-gateway
Example
#route del -net 10.10.10.0/24 gw 192.168.0.1
Deleting default gateway
#route del default gw default-gatway
Example :
#route del default gw 192.168.0.1
Deleting specific host from routing table
#route del -host ip-add gw default-gateway
Example
#route del -host 10.10.10.45 gw 192.168.0.1
Seeing routing table
#netstat -rn
#route
Note : The old gate way will still remain and may need to be taken out for the system to function properly. Routes are made permanent in Linux by adding routes to /etc/sysconfig/static-routes.
