Static Routes Example
Goal and situation
A connection of subnet 2 and subnet 3 to the internetworks 17.0.0.0, 75.0.0.0 and
126.0.0.0 is desired. Only router X is connected to these internetworks. However,
no connection to the internetworks 17.0.0.0, 75.0.0.0 and 126.0.0.0 via router X
is possible at this point as router X does not run RIP.
Solution
To establish a connection to the internetworks 17.0.0.0, 75.0.0.0 and 126.0.0.0
for subnets 2 and 3, a static route to the nets 17.0.0.0, 75.0.0.0, 126.0.0.0 via
Router X must be created for both routers 1 and 2. Routers 1 and 2 then announce
these static routes via RIP, meaning that the route to the internetworks 17.0.0.0,
75.0.0.0 and 126.0.0.0 is known by Routers 3 and 4 which make the internet-
works reachable from subnets 2 and 3.
