IP PREFIX LIST

ip prefix-list

Overview Use this command to create an entry for an IPv4 prefix list.
Use the no variant of this command to delete the IPv4 prefix-list entry.
Syntax ip prefix-list <list-name> [seq <1-429496725>] {deny|permit}
{any|<ip-prefix>} [ge <0-32>] [le <0-32>]
ip prefix-list <list-name> description <text>
ip prefix-list sequence-number
no ip prefix-list <list-name> [seq <1-429496725>]
no ip prefix-list <list-name> [description <text>]
no ip prefix-list sequence-number
Mode Global Configuration
Usage When the device processes a prefix list, it starts to match prefixes from the top of
the prefix list, and stops whenever a permit or deny occurs. To promote efficiency,
use the seq parameter and place common permits or denials towards the top of
the list. If you do not use the seq parameter, the sequence values are generated in
a sequence of 5.
The parameters ge and le specify the range of the prefix lengths to be matched.
When setting these parameters, set the le value to be less than 32, and the ge value
to be less than or equal to the le value and greater than the ip-prefix mask length.
Prefix lists implicitly exclude prefixes that are not explicitly permitted in the prefix
list. This means if a prefix that is being checked against the prefix list reaches the
end of the prefix list without matching a permit or deny, this prefix will be denied.
