IP Routing Policy Configuration Commands

229

permit

Enter to specify the match mode of the defined address prefix list items as

permit mode.

deny

Enter to specify the match mode of the defined address prefix list items as

deny mode.

network

Enter the IP address prefix range (IP address). If it is 0.0.0.0 0, all the IP

addresses are matched.

len

Enter the IP address prefix range (mask length). If it is 0.0.0.0 0, all the IP

addresses are matched.

greater_equal

,

less_equal

The address prefix range [greater-equal, less-equal]

to be matched after the address prefix network len has been matched. The

meaning of

greater

-

equal

is "larger than or equal to" , and the meaning of

less-equal

is "less than or equal to". The range is len <= greater-equal <=

less-equal <= 32. When only

greater-equal

is used, it denotes the prefix range

[greater-equal, 32]. When only

less-equal

is used, it denotes the prefix range

[len, less-equal].

Description

Use the

ip ip-prefix

command to configure an address prefix list or one of its

items.

Use the

undo ip ip-prefix

command to delete an address prefix list or one of its

items.

By default, there’s no address prefix list.

The address prefix list is used for IP address filtering. An address prefix list may

contain several items, and each item specifies one address prefix range. The

inter-item filtering relation is "OR", i.e. passing an item means passing the filtering

of this address prefix list. Not passing the filtering of any item means not passing

the filtration of this prefix address list.

The address prefix range may contain two parts, which are determined by

len

and

[

greater-equal, less-equal

] respectively. If the prefix ranges of these two parts

are both specified, the IP to be filtered must match the prefix ranges of these two

parts.

If you specify

network len

as 0.0.0.0 0, it only matches the default route.

Example

The prefix address list of this address indicates to match the bits 1 to 8 and the bits

17 to 18 for filtering the IP address with the bits 1 to 8 and the bits 17 to 18 of the

specified IP network segment 10.0.192.0.
