hcip06 ospf特殊区域综合实验

2022-07-30 09:06:00 【土尔奇酱】

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
