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
If no ge or le parameters are specified, an exact match is assumed. If only ge is specified, the range is
assumed to be from ge-value to 32. If only le is specified, the range is assumed to be from len to le-value.
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.
Usage Examples
The following example creates a prefix list entry in the prefix list
test
matching only the 10.0.0.0/8 network:
ProCurve(config)#
ip prefix-list test seq 5 deny 10.0.0.0/8
The following example creates a prefix list entry in the prefix list
test
matching any network of length 24 or
less:
ProCurve(config)#
ip prefix-list test seq 10 permit 0.0.0.0/0 le 24
