CN2510 User’s Manual Setting Up Routing
13-6
For this example, the Notebook PC dials in to the CN2510 to request a connection to Internet host
210.48.96.9 (for example), which is not on local network 203.67.6. This causes CN2510 to act as a
router and send the datagram to the default next-hop router, 203.67.6.254. In this case we should
add the default gateway IP address (203.67.6.254) to the routing table, as shown in the following
figure, to handle hops to any destination beyond the local network (203.67.6).

For this example, in addition to sending requests to the Internet, dial-in users can make requests to
Intranet hosts 202.65.66.4 or 202.65.66.5, which are on network 202.65.66 (located outside
network 203.67.6). In this case, add a route entry for the next-hop router, 203.67.6.252, that
delivers requests to network 202.65.66. The metric hop in this case is 2 route hops.
