# CCNP Linkstate
Link-State
鏈結狀態路由協定包含 OSPF、IS-IS 等協定。
* 連結速度 (實際頻寬)
鏈結狀態路由協定是以連結速度為基礎的計算方式,用來定義從一段網路到另一段網路的距離。而更新資訊也只有 Topology 有異狀時,才會使用鏈結狀態的廣播(通告) LSA, Link-State Advertisement 。
* 路徑處理
1. 發現路徑, Discovery
2. 選擇路徑, Selection
3. 維護路徑, Maintanance

* 定期更新
倘若無異常狀態促使觸發更新,則路由表會預設時間從半小時至兩小時自動更新。
* 預設距離值
