EXAMPLE
Figure 16-8 illustrates an OSPF network that is similar to the network used previously
in the RIP example. In this example, access to the Internet is accomplished by using the
ASBR function on the switch labeled Internet. As a result, all routes to the Internet will
be done through external routes. Suppose the network administrator wishes to only
allow access to certain internet addresses falling within the range 192.1.1.0/24 to the
internal backbone.
