Where are the routing tables stored?

A. The routing table is not a file, but the routing information is stored in the kernel. You can use the command “route -n” to display the table. The route table is empty on boot. # route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 128.128.92.0 0.0.0.0 255.255.252.0 U 0 0 0 eth0 127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo 0.0.0.0 128.128.92.1 0.0.0.0 UG 0 0 0 eth0 You will need to configure the default route into the operating system, which writes it to the kernel forwarding table when networking is started. When making changes or modifying the route table, the /etc/sysconfig/network gets modified. Once the file has been modified, rather than rebooting, you can make your changes take effect by running: # /etc/init.d/network restart NOTE: Please do not use routed. CIS recommends that you turn off any and all un- necessary processes for security reasons. Routed is not used within the context of the WHOI domain.
