ospf多区域中nssa默认路由的设置
实验报告
实验目的：
通过本实验实现完全nssa区域，和实现默认路由的方法。
第一步：
配置路由器ip地址
Router1上的设置
R1（config）#interfaces0/0
R1（config-if）#ipadd192.168.1.1255.255.255.0
R1（config）#interfaceloopback0
R1（config-if）#ipadd1.1.1.1255.255.255.0
Router2-router4同理
第二步：
启用路由协议
Router1（asbr路由器，将loopback口重分布进OSPF协议）-router2启用OSPF协议，router4启用rip协议，router3启用OSPF和rip协议（asbr路由器）
Router1上的设置
R1（config）#routerospf1
R1（config-router）#network192.168.1.00.0.0.255area1
R1（config）#routerospf1
R1（config-router）#redistributeconnectedsubnets
R1（config-router）#area1nssa
Router2上的设置
R2（config）#routerospf1
R2（config-router）#network192.168.1.00.0.0.255area1
R2（config-router）#network192.168.2.00.0.0.255area0
R2（config-router）#network2.2.2.00.0.0.255area0
R2（config-router）#area1nssa
Router3上的设置
R3（config）#routerospf1
R3（config-router）#network192.168.2.00.0.0.255area0
R3（config-router）#network3.3.3.00.0.0.255area0
R3（config）#routerrip
R3（config-router）#version2
R3（config-router）#network192.168.3.0
R3（config-router）#noauto-summary
Router4上的设置
R4（config）#routerrip
R4（config-router）#version2
R4（config-router）#network192.168.3.0
R4（config-router）#network4.4.4.0
R4（config-router）#noauto-summary
第三步：
设置路由重分布（在router3上设置）
R3（config）#routerrip
R3（config-router）#redistributeospf1metric2
R3（config）#routerospf1
R3（config-router）#redistributeripsubnetsmetric1000
第四步：
查看路由表
