相比于Stub区域,NSSA区域能够将自治系统外部路由引入并传播到整个OSPF自治系统中,同时又不会学习来自OSPF网络其它区域的路由。 在NSSA区域中,为保证到自治系统外的路由可达,NSSA区域的ABR将生成一条缺省路由,并发布给NSSA区域中的其他路由器。 在NSSA区域中,可能同时存在多个ABR,为了防止路由环路产生,边界路由器之间不计...

For Type 3 LSAs, you can configure a sender to determine whether to set the DN bit to 1 or configure a receiver to determine whether to check the DN bit in the Type 3 LSAs based on the router ID of the device that generates the LSAs. In an inter-AS VPN Option A scenario as ...
