or

ip as-path access-list number permit regular-expression

or

ip prefix-list name permit prefix/length

or

ip community-list number permit community-number

route-map name permit sequence-number
 match ip address access-list-number

or

match as-path access-list-number

or

match ip address prefix-list list-name

or

match community community-list-number
