IP prefix lists

Use prefix lists to permit or deny an address or range of addresses. Filtering by a prefix list involves matching the prefixes of routes with the prefixes listed in the prefix list. An implicit deny is assumed if a prefix does not match any entries in a prefix list. Prefix lists can be configured for both IPv4 and IPv6 addresses.

Users can configure multiple entries in a prefix list and permit or deny the prefixes that match the entry. Each entry has an associated sequence number.
