Following are some examples that explain how to set up network filters in the
internet, as shown in Figure 13.
The following steps show how to filter Network 6-10 so that it is not visible to
Network 16-20 as shown in Figure 13.
1. Add an output network filter for Network 6-10 to Interface 2 on Router B.
AP2 config>add nfilter out
Interface # [0]? 2
