greater-equal,
less-equal: The
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].

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.
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.
[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.

permit: Specifies the match mode of the defined Route-policy node as permit

filtration, the Apply sub-statement of this node will be executed on the route.
Otherwise, the route will be tested by the next node.
