プレフィックスリストの作成
Router(config)#ip prefix-list {list-name [seq number] {deny | permit} network/length [ge ge-length] [le le-length] | description 説明 | sequence-number}

ルートマップを作成します。
Router(config)#route-map map-tag [ permit | deny ] [sequence-number]

作成したプレフィックスリストやアクセスリストを使用して、どのルートをリークするかを定義します。
Router(config-route-map)#match ip address { access-list-number [ access-list-number . .. | access-list-name . .. ] | access-list-name [ access-list-number . .. | access-list-name ] | prefix-list prefix-list-name [ prefix-list-name . .. ] }
