Use the ip prefix-list seq command to specify a prefix to be matched or a range of mask lengths.
Syntax Description
<listname> Specifies a particular prefix list.
<sequence#> Specifies the entry's unique sequence number which determines the processing
order. Lower-numbered entries are processed first. Range: 1 to 4,294,967,294.
permit Permits access to matching entries.
deny Denies access to matching entries.
<network/len> Specifies the network number and network mask length.
le <le-value> Specifies the upper end of the range. Range: 0 to 32.
ge <ge-value> Specifies the lower end of the range. Range: 0 to 32.
Default Values

Functional Notes
This command specifies a prefix to be matched. Optionally, it may specify a range of mask lengths. The
following rule must be followed: len < ge-value
<
le-value. A prefix list with no entries allows all routes. A
route that does not match any entries in a prefix list is dropped. As soon as a route is permitted or denied,
there is no further processing of the rule in the prefix list. A route that is denied at the beginning entry of a
prefix list will not be allowed, even if it matches a permitting entry further down the list.
