Description 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 all items means not passing the filtering
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.
Specify network len as 0.0.0.0 0 less-equal 32 to match all the routes.
