1. Display the RIP Global Filter Table.
2. Select an entry in the table.
3. Click . The entry is deleted.
4. Click . When the Status field displays "Finished!", the fields are confirmed as modified.
To display the RIP Circuit Filter Table:
1. Display the IPX RIP/SAP Filter window.
2. Press the RIP Circuit Filter button. The RIP Circuit Filter Table opens:
Figure 6- 157. RIP Circuit Filter Table window
The RIP Circuit Filter Table displays the following parameters:
♦ Type – Defines whether the current filter entry works on traffic coming into or out of the
device.
♦ 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.
