ip prefix-list
ip prefix-list
Creates a prefix list or adds a prefix-list entry. The no form of this command deletes a prefix-list
entry.
Syntax ip prefix-list name [seq seq-value] [description string] {deny | permit}
network-addr/mask-bits [ge ge-value] [le le-value]
no ip prefix-list name [seq seq-value] [description string] {deny | permit}
network-addr/mask-bits [ge ge-value] [le le-value]
Command
Default
Parameters name Specifies the prefix list name.
seq seq-value (Optional) The sequence number of the prefix-list entry. If you do not specify a
sequence number, a default seq-value is applied beginning with prefix-list
entry 5. Subsequent unnumbered entries are incremented by 5. The
prefix-list entries are interpreted in numerical order, beginning with the lowest
sequence number.
description string (Optional) Text string describing the prefix list.
deny The software denies access if the neighbor route is in this prefix list.
permit The software permits access if the neighbor route is in this prefix list.
network-addr/mask-bits
Specifies the network address and the number of bits in the network mask.
ge ge-value (Optional)
If you specify only ge ge-value, then the mask-length range is from ge-value to
32.
If you specify both ge ge-value and le le-value, the ge ge-value must meet the
condition: length < ge-value <= le-value <= 32.
If you do not specify ge ge-value or le le-value, the prefix list matches only on
the exact network prefix you specify with the network-addr>/<mask-bits
parameter.
le le-value (Optional)
If you specify only le le-value, then the mask-length range is from length to
le-value.
If you specify both ge ge-value and le le-value, the ge ge-value must meet the
condition: length < ge-value <= le-value <= 32.
If you do not specify ge ge-value or le le-value, the prefix list matches only on
the exact network prefix you specify with the network-addr>/<mask-bits
parameter.
Command
Modes
Global configuration mode.
Usage
Guidelines
An IP prefix list specifies a list of networks. When you apply an IP prefix list to an area, the device
sends or receives only a route whose destination is in the IP prefix list. The software interprets the
prefix lists in order, beginning with the lowest sequence number.
