# Searchable Keywords: route router netmask 

The route cmd can be used to view the current routing tables
as well as add a new route to a network or delete a route.

View current routes:
# route -e

Add a default router:
# route add default gw 192.168.100.1

Add route to a differnent subnet:
# route add -net 192.168.200.0 netmask 255.255.255.0 dev eth0
NOTE: 
- no dash in front of the netmask or add -
- you can use this to add routes to different physical interfaces
	ie  eth1, eth2...etc it does NOT work well with virtual 
		dual home intefaces(eth0:1) it defaults to the
			eth0 interface default route.

Delete a route(this is a long string):
# route del -net 192.168.200.0 netmask 255.255.255.0 gw 192.168.200.1 dev eth0

Rejecting route(I think this means refuse connections from this network):
# route add -net 10.10.0.0 netmask 255.255.0.0 reject

Alternatively in Redhat(and probably other linux distros) Linux, you can add 
the following two lines to the file "/etc/sysconfig/static-routes":

eth0 net 192.168.200.0 netmask 255.255.255.0 gw 192.168.200.1
eth1 net 192.168.100.0 netmask 255.255.255.0 gw 192.168.100.2

The commands to delete the above routes with route are:

route del -net 192.168.200.0 netmask 255.255.255.0 gw 192.168.200.1 dev eth0
route del -net 192.168.100.0 netmask 255.255.255.0 gw 192.168.100.2 dev eth1
