Upgrading Routers from Version 5 to Version 10.0
A-4
Figure A-1 shows the result of a drop-all filter (filter at Precedence Level 8)
working in combination with more specific, higher-precedence filters (filters at
Precedence Levels 1 through 7) on an interface.
• The fields shown in this example are IP address ranges (although you can
choose any appropriate field).
• The Filtered Result shown at the top of the diagram indicates IP address
intervals over which the interface will drop or accept packets it receives.
• Note that the highest precedence filter in a given address range determines the
final result of combined filtering within that range.
• Note that each precedence level supports only one Version 10.0 filter. (Version
5 software allowed you to configure multiple filters at the same precedence
level.)
