Basic static IP routing example
Figure 32
shows an Internetwork consisting of three routers, an IPLink device in the middle, and the four
autonomous networks, with network addresses 10.1.5.0/16, 172.16.40.0/24, 172.17.100.0/24, and 10.2.5.0/
16. The IPLink shall be configured for the following IP routing scenario:
All packets for the Workstation with IP address 10.1.5.10 shall be forwarded to the next-hop router Calvin. All
packets for network 10.2.5.0/16 shall be forwarded to the next-hop router Hobbes.

The necessary routing-table entries for the scenario described are listed below.
