(IP address prefix list - the prefix list) can accurately match the network number + prefix length, but cannot be used for packet filtering, contrary to the ACL, declined to that does not match,

Match rule:
Greater - equal or greater
Less - equal or less
At the same time, with greater - equal + less - equal (greater than or equal to the decimal, large Numbers less than or equal to)
Not only allows a subnet mask of the network number by

All routing:
Permit 0.0.0.0 0 less - equal 32
The host routing:
Permit 1.1.1.1 32
The default route:
Permit 0.0.0.0 0

Eg:
In the simplest way matching
192.168.4.0/24;
192.168.5.0/24;
192.168.6.0/24;
192.168.7.0/24

Permit greater 192.168.4.0 22-24 less equal - equal 24


The ACL can't exactly match
