Configuring Prefix Lists

This topic identifies the Cisco IOS command that is required to configure prefix-list filters.

Configuring Prefix-Lists


ip prefix-list list-name [seq seq] {permit|deny} network/len [ge value] [le value]

• Prefix-lists have names and sequence numbers (like route-maps).

• An entry with no le or ge parameter matches exactly the specified prefix.

• An entry with an le or ge parameter matches any route within the address space of address/prefix with prefix longer or equal to ge value and shorter than or equal to le value.
