What does that say?
When you have more than one router on a network, you must “introduce”
them to each other. For example, you may have 3 routers on your network,
one for sales, support and accounting, and you want to keep the departments
separate but you want all of them to have access to Internet. You will do this
by “introducing” the routers to each other using static routing. In each router
you will enter the IP address and subnet mask, of the other two routers,
creating a chain of routers, allowing all of them to have access to the Internet.

Routing
Routing, also know as Static Routing, is used to establish IP packet routing without requiring the devices to
communicate with each other. This is considered a “No Fault” network, because there is no way for the network
to recover in the event failure.
