Netopia Router PN Series - Manual (Page 250)

B-14 Reference Guide
The Netopia Router’s connection profiles for Routers B and C create
entries in its IP routing table. One entry points to the subnet
a.b.c.128, while a second entry points to the subnet a.b.c.248. The
IP routing table might look similar to the following:

UPDATE
Let’s see how a packet from the Internet gets routed to the host
with IP address a.b.c.249, which is served by Router C. The packet
first arrives at Router A, which delivers it to its local network
(a.b.c.0). The packet is then received by the Netopia Router, which
examines its destination IP address.
