This excludes Manufacturing zone information from entering Router A, thereby
filtering the zone from the rest of the internet.
Example 2
The following example shows how to filter the Manufacturing zone from Network
11-15, but still allow the Manufacturing zone to be visible on Network 1-5. To do
this, you would set up an output filter on Interface 3 of Router A to exclude
Manufacturing zone information from being forwarded out of Interface 3. The
interface will continue to advertise Manufacturing zone information over interfaces 1
and 2 on Router A, making it visible on Network 1-5.
1. Add an output zone filter to Interface 3.
AP2 config>add zfilter out
Interface # [0]? 3
Zone name []? Manufacturing
2. Enable the output zone filter and make the filter exclusive.
AP2 config>enable zfilter out exc
Interface # [0]? 3
This filter excludes Manufacturing zone information from the output of
Interface 3.
Example 3
The next example shows how to set up a filter so that the Admin zone is visible on
all networks, but the Finance zone is not visible to the rest of the internet.
1. Add an input zone filter to Interface 2 on Router A.
AP2 config>add zfilter in
Interface # [0]? 2
Zone name []? Admin
2. Enable the input zone filter and make it inclusive.
AP2 config>enable zfilter in inc
Interface # [0]? 2
By setting up this input filter as inclusive, only Admin zone information is
forwarded through Interface 2 to the rest of the internet.
Setting Up Network Filters
Network filters are similar to zone filters, except they let you filter an entire network.
To set up a network filter:
1. Add a network filter. Use the add nfilter in command to add an input network
filter to an interface. Use the add nfilter out command to add an output
network filter to an interface. For example:
AP2 config>add nfilter out
Interface # [0]? 2
First Network range number (decimal) [0]? 11
Last Network range number (decimal) [0]? 15
The network range you enter here must match the range that you assigned to
that network.
2. Enable the network filter that you added and make it either inclusive or
exclusive. Inclusive filters forward only network information in that filter.
Exclusive filters block only network information in a filter, and they allow all other
network information to be forwarded.
AP2 config>enable nfilter in exc
Interface # [0]? 2
