拓扑图
。
实验要求
1,R4为ISP,其上只能配置IP地址;R4与其他所有直连设备间均使用公有IP
2,R3-R5/6/7为MGRE环境,R3为中心站点;
3,整个OSPF环境IP基于172.16.0.0/16划分;
4,所有设备均可访问R4的环回;
5,减少LSA的更新量,加快收敛,保障更新安全;
6,全网可
实验思路
- 先划分172.16.0.0/16IP地址
- 再配置IP地址
- 公网通(缺省路由)
- 配置OSPF,RIP,路由引入RIP
- 配置MGRE,R3为中心站点,ospf宣告隧道
- 修改接口类型,取消选举
- 多进程重发布area4
- 配置easyIP
- 路由聚合(优化骨干),R3,5,6,7传入区域聚合,R9(进程1),12(ospf协议视图)ASBR聚合
- 设置特殊区域(优化非骨干区域),area1完全末梢,area3,area2完全非纯末梢,会自动下发缺省(能够访问R4环回)
- 加快收敛,修改Hello时间ospf timer hello 5
- 保证更新安全,区域认证
