Network Address – The network pattern to affect the filter entry. The network
pattern works in conjunction with the network mask to define the filter entry.
Network Mask – Type in the letters F, 8, C, E, and 0 as many times as desired to
indicate which part of the network pattern is important. The mask must be
continuous from left to right. 00000000 means all addresses, ffffffff means one
address (no address range). A combination of f 0 indicates a specific range. This
combination must have f on the left side, 0 on the right side, and a single F, 8, C,
or E, or 0 between them.
For example, if the network pattern is set to 12345678, set the network
mask to ffff0000 to indicate that only the first four numbers of the network
pattern are checked, and the remaining numbers are irrelevant. In this
example, only RIP messages with the numbers 1234 as their first four
digits are affected.
Action – Defines whether the indicated packets are forwarded (permit) or blocked
(denied) when the current filter entry conditions are met. This parameter can be
used to fine-tune other filter entries. For example, a filter entry can be set to block
all RIP messages with a network pattern starting with 123, and set another filter
entry to permit all RIP messages with a network pattern starting with 1234. As a
result, all RIP messages with a network pattern starting with 123 that do not have 4
as the fourth digit are blocked.
