X.25 and Frame Relay provide an optional broadcast capability that can be configured in the map to allow OSPF to run as a broadcast network. See the x25 map and frame-relay map command pages in the Cisco IOS Wide-Area Networking Command Reference publication for more detail. OSPF...
A network segment can belong to only one area. In other words, you need to specify an area for each interface running OSPF. OSPF runs on an interface only when both of the following conditions are met: The mask length of the interface's IP address is greater than or equal to ...

Figure 7-1 DR in Multi-Access Network Areas You can limit the CPU and memory requirements that OSPFv3 puts on the routers by dividing an OSPFv3 network into area s. An area is a logical division of routers and links within an OSPFv3 domain that creates separate...
OSPF协议是大中型网络上使用最为广泛的IGP(Interior Gateway Protocol)协议。节点在创建邻接,接受链路状态通告(Link-state Advertisement,LSA)时,可以通过MD5或者明文进行安全验证。 OSPF提出了“区域(Area)”的概念,一个网络可以由单一区域或者多个区域组成。其中,一个特别的区域被称为骨干区域(Backbone Area),该区域是...
B. All routers exchange routing tables with each other in a multipoint network. C. Packets are routed based upon the shortest path to the destination. D. Paths are chosen depending on the cost efficiency factor. E. Every router in an OSPF area is capable of representing the entire network...
