Route manipulates the kernels IP routing tables. Its primary use is to
set up static routes to specific hosts or networks via an interface after
it has been configured with the ifconfig program.
Add Route :
# route add -net < network > netmask <subnet/netmask> gw < gateway>
Ex - route add -net 10.20.3.0 netmask 255.255.255.0 gw 10.20.2.1
OR
# route add -net < network > netmask <subnet/netmask> gw < gateway> <device>
Ex - route add -net 10.20.3.0 netmask 255.255.255.0 gw 10.20.2.1 eth1
Delete Route :
# route del -net < network > netmask <subnet/netmask> gw < gateway>
Ex - route del -net 10.20.3.0 netmask 255.255.255.0 gw 10.20.2.1
OR
# route del -net < network > netmask <subnet/netmask> gw < gateway> <device>
Ex - route del -net 10.20.3.0 netmask 255.255.255.0 gw 10.20.2.1 eth1
