prefix list, the route is denied without further check. If otherwise, the IP address is
checked against the next address prefix entry.
network: The IP address prefix range (IP address). If it is 0.0.0.0 0, all the IP addresses
are matched.
len: 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.
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.
If you specify network len as 0.0.0.0 0 less-equal 32, it matches all routes.
Example
# Define an address prefix list named “p1”, permitting the routes of the network
segment 10.0.192.0 8 with a mask length of 17 or 18 to pass.
[Quidway] ip ip-prefix p1 permit 10.0.192.0 8 greater-equal 17 less-equal 18
