About the Filtering Table
The filtering table should be viewed as
pipelined sets of parame-
ters
that determine whether any given packet is forwarded from
one segment to the other. Each parameter set contains three
ranges and an ON/OFF switch.
The following flowchart shows packet flow in the pipeline.
