User Guidelines Prefix lists allow matching of route prefixes with those specified in the prefix list. Each prefix list includes of a sequence of prefix list entries ordered by their sequence numbers. A router sequentially examines each prefix list entry to determine if the route's prefix matches that of the entry. An empty or nonexistent prefix list permits all prefixes. An implicit deny is assumed if a given prefix does not match any entries of a prefix list. Once a match or deny occurs the router does not go through the rest of the list. A prefix list may be used within a route map to match a route's prefix using the match ip address command. The command no ip prefix-list list-name deletes the entire prefix list. To remove an individual statement from a prefix list, you must specify the statement exactly, with all its options. Up to 128 prefix lists may be configured. The maximum number of statements allowed in prefix list is 64. Command History Introduced in version 6.2.0.1 firmware. Example The following example configures a prefix list that allows routes with one of two specific destination prefixes, 172.20.0.0 /16 and 192.168.1.0 /24: console(config)# ip prefix-list apple seq 10 permit 172.20.0.0/16 console(config)# ip prefix-list apple seq 20 permit 192.168.10 0.0.0.255 The following example disallows only the default route. console(config)# ip prefix-list orange deny 0.0.0.0/0 console(config)# ip prefix-list orange permit 0.0.0.0/0 ge 1 ip prefix-list description To apply a text description to a prefix list, use the ip prefix-list description command in global configuration mode. To remove the text description, use the no form of this command. Layer 3 Routing Commands 1420
