The route being hidden from the rest of the network is defined by the
Accounting department network with IP network address 151.1.0.0. Router
C's connection to the departments outside Accounting is through the FDDI
backbone. The destination from which network 151.1.0.0 is hidden is most
easily defined as the FDDI interface to the backbone. Figure 5 shows the
internetwork topology.
Note that Router C has the route to network 151.1.0.0 in its routing table. If
Router C receives a packet from the FDDI backbone that is destined for
network 151.1.0.0, it forwards the packet.
