    • In one embodiment, a method includes receiving on a first communication link at a local router all routing information at a certain level of detail for each router of multiple routers communicating in a first flooding domain. A measure of distance is determined from a particular router in the first flooding domain to the local router. It is determined whether the measure of distance exceeds a threshold. If the measure of distance exceeds the threshold, then summary routing information with less than the certain level of detail is determined for the particular router. Also, certain routing information is sent over a different second communication link at the local router. The certain routing information includes the summary information for the particular router, and all routing information at the certain level of detail for a subset of routers communicating in the first flooding domain, which subset excludes the particular router.
    • 在一个实施例中,一种方法包括在本地路由器的第一通信链路上以在第一泛洪域中通信的多个路由器的每个路由器的一定详细级别接收所有路由信息。 从第一个洪泛域中的特定路由器到本地路由器确定距离的度量。 确定距离测量是否超过阈值。 如果距离测量值超过阈值,则确定特定路由器具有小于特定级别细节的汇总路由信息。 而且,通过本地路由器上的不同的第二通信链路发送某些路由信息。 某些路由信息包括特定路由器的摘要信息,以及在第一洪泛域中通信的路由子集的特定级别的所有路由信息,该子集排除特定路由器。
