我们以３个地方的区域划分为例，进行OSPF路由协议的实施配置。<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />OSPF路由协议的配置过程6-11 OSPF路由协议的监测命令 具体配置：由于拓扑结构中的路由器过多，我们只选取图中比较有代表性的Router1、Router2、Rourter3、Rourter4路由器进行配置演示。Router1:interface serial s 0/1ip address 10.0.0.1 255.255.255.0 encapsulation pppinterface serial s 0/2ip address 10.0.1.1 255.255.255.0 encapsulation pppinterface serial s 0/3ip address 10.0.2.1 255.255.255.0encapsulation pppinterface loopback 0ip address 1.1.1.1 255.255.255.0router ospf 100network 10.0.0.0 0.0.0.255 area 0network 10.0.1.0 0.0.0.255 area 0network 10.0.2.0 0.0.0.255 area 0Router 2interface serial 0/1ip address 10.0.0.2 255.255.255.0encapsulation pppinterface serial 0/2 ip address 10.1.0.2 255.255.255.0encapsulation pppinterface serial 1/0ip address 10.10.1.1 255.255.255.0encapsulation pppinterface serial 1/1ip address 10.10.2.1 255.255.255.0encapsulation pppinterface serial 1/2ip address 10.10.3.1 255.255.255.0encapsulation pppinterface loopback 0ip address 2.2.2.2 255.255.255.0router ospf 200network 10.0.0.0 0.0.0.255 area 0network 10.0.0.0 0.0.0.255 area 0network 10.10.1.0 0.0.0.255 area 3network 10.10.2.0 0.0.0.255 area 3network 10.10.3.0 0.0.0.255 area 3area3 virtual-link 3.3.3.3//配置虚链路时区域标识是3，表示虚链路是在区域3中建立的；路由器标识指定的是路由器B的标识，表示路由器C与路由器B建立虚链路Router3 interface serial 0ip address 10.10.1.1 255.255.255.0 encapsulation pppinterface serial 1ip address 10.20.0.1 255.255.255.0encapsulation pppinterface loopback 0ip address 3.3.3.3 255.255.255.0router ospf 300network 10.10.1.0 255.255.255.0 area 3network 10.20.0.0 255.255.255.0 area 4 area 3 virtual-link 2.2.2.2Router4 interface serial 0ip address 10.20.0.2 255.255.255.0 encapsulation ppprouter ospf 400network 10.20.0.0 0.0.0.255 area 4
