WAN standards typically describe both physical layer delivery methods and data link layer requirements, including physical addressing, flow control, and encapsulation. 廣域網(wǎng)路標準典型地描述實(shí)體層的傳送方法和資料鏈結層的需求，包括實(shí)體層定址，流量控制和封裝。
When this feature is disabled any packets received that are destined for a subnet that falls within the subnetwork addressing scheme of the router will be discarded. 如果此功能被停用，當路由器收到目的地為特定子網(wǎng)路的封包，而這些子網(wǎng)路正好在路由器的子網(wǎng)定址機制內，則這些封包將被丟棄。
