Default Configuration No prefix lists are configured by default. Command Mode Global Configuration User Guidelines The ipv6 prefix-list command is used to create IPv6 prefix lists. These are similar to ip prefix lists except that the lists are IPv6 specific. An IPv6 prefix list can contain only IPv6 addresses. Prefix lists allow matching of route prefixes against those specified in the prefix list. Each prefix list includes of a sequence of prefix list entries ordered by sequence numbers. A router examines each prefix list entry in sequential order to determine if the route's prefix matches that of the entry. For IPv6 routes, only IPv6 prefix lists are matched. An empty or non-existent 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 occurs the router does not perform matching on the rest of the list. An IPv6 prefix list may be used within a route map to match a route's prefix using the match ipv6 address command. A route map may contain both IPv4 and IPv4 prefix lists. If the route being matched is an IPv6 route, only the IPv6 prefix lists are matched. When neither the ge nor the le option is configured, the destination prefix must match the ipv6-prefix/prefix-length exactly. If the ge option is configured without the le option, any prefix with a ipv6-prefix greater than or equal to the ge value is considered a match. Similarly, if the le option is configured without the ge option, a prefix with a network mask less than or equal to the le value is considered a match. No description is configured by default for an IPv6 prefix list. The command no ipv6 prefix-list list-name deletes the entire prefix list. To remove an individual statement from a prefix list, 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. These numbers indicate only IPv6 prefix lists. IPv4 prefix lists may be configured in appropriate numbers independently.
