CiscoIOSSoftware,7200Software(C7200-ADVSECURITYK9-M), Version 12.4(11)T, RELEASE SOFTWARE (fc2)
PC机一台
三．实验原理
1.地址划分：
R1------R2：12.1.1.0/24 R1---------R3:13.1.1.0/24
R2---------R4:100.1.1.1/24 R3---------R4:100.1.1.0/24
R4---------R5:45.1.1.0/24 R4---------R6:46.1.1.0/24
R6---------R7:67.1.1.0/24 R6---------R8:68.1.1.0/24
2.环回地址创建：
R1：Loopback1 1.1.1.1/24 Loopback10 202.1.1.1/24
Loopback20 202.1.2.1/24 Loopback30 202.1.3.1/24
R2:Loopback2 2.2.2.2/24
R3:Loopback3 3.3.3.3/24
R4:Loopback4 4.4.4.4/24
R5:Loopback5 5.5.5.5/24 Loopback10 200.1.1.1/24
Loopback20 200.1.2.1/24 Loopback30 200.1.3.1/24
R6:Loopback6 6.6.6.6/24
R7:Loopback7 7.7.7.7/24 Loopback10 199.1.1.1/24
Loopback20 199.1.2.1/24 Loopback30 199.1.3.1/24
R8:Loopback8 8.8.8.8/24
3.区域划分：
Area 1 ：R1,R2,R3（stub 末节区域）
Area 0 :R2,R3,R4(骨干区域)
Area 2:R4,R6（stub 末节区域）
Area 3:R6,R8
4.路由运行协议：
OSPF 100:R1，R2，R3，R4，R6，R8
EIGRP 90：R4，R5
RIP VER2：R6，R7
Frame relay:R9
5.在area1，area2设置stub区域，过滤4类，5类LSA。
6.在R3上修改OSPF cost值，使之传递到R4的路由条目的cost 值大于R4接收到的路由，在R4的路由表中只出现从R2传递过来的路由条目。
7.在各个ASBR路由器上重分发外部路由，并且进行路由汇总，优化路由条目。
8.在R4-------R6上建立tunnel隧道，完成非骨干区域与骨干区域的连接。地址为192.168.1.0/24.
9.全网汇总，优化路由条目。
10.使用distribute-list 过滤200.1.1.1/24,并且在R5上发布一条缺省路由。使之全网可达。

五．实验结果及问题分析
R1路由表
R2路由表
R3路由表
R4路由表
R5路由表
R6路由表
R7路由表
R8路由表
全网可达
结论：
在stub区域，virtual-link虚拟链路不能启用，需要通过tunnel隧道实现OSPF区域的规则区域连接骨干区域。
在配置OSPF的单播邻居时，接口需要为point-to-multi网络类型或者为NBMA网络类型。
