Network Mask – Type in the letters F, 8, C, E, and 0 as many times as desired to
indicate which network pattern part 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 fs and 0s 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, the network mask
can be set to ffff0000. This indicates that only the first four network
pattern numbers 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. The parameter is used to
fine-tune other filter entries.
For example, set a filter entry 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.
The default is forward, but the default can be set by creating a general
filter entry with the network mask 00000000, and setting it to permit or
deny.
