实验题目

拓扑图

分析：
缺省路由+NAT
MGRE环境配置
OSPF协议
重发步——在ASBR上面配置
域间路由汇总、域外路由汇总——分别在ABR和ASBR上配置
空接口防环路由——在黑洞路由上配置
特殊区域——area1可以设置为完全末梢区域,area2和area3可以设置为完全NSSA区域
更改hello时间
OSPF认证
测试全网可达

配置内容：

[r1-GigabitEthernet0/0/0]ospf timer hello 5
//加快收敛只需要去接口配置减少OSPF的hello时间即可,修改时,所有邻居关系的hello time都要一致,否则将不会建立邻居关系

[r1-GigabitEthernet0/0/0]ospf authentication-mode md5 1 cipher 123
//保证更新安全性只需要去对应接口配置接口认证,与hello time一致,若修改,与之建邻的接口都需配置认证,且认证的密钥都需一致
