HCIP 重发布实验

IP如图

一、配置静态
[r4]ip route-static 10.5.5.5 32 10.1.16.2
[r5]ip route-static 0.0.0.0 0 10.1.16.1
二、配置RIP
[r1]rip
[r1-rip-1]v 2
[r1-rip-1]undo su
[r1-rip-1]undo summary
[r1-rip-1]net 10.0.0.0
R2 R3 同理
三、配置OSPF
[r2]ospf 1 r
[r2]ospf 1 router-id 2.2.2.2
[r2-ospf-1]a 0
[r2-ospf-1-area-0.0.0.0]net 10.1.14.0 0.0.0.255
其他同理

四、重发布
[r2-ospf-1]import-route rip
[r2]rip
[r2-rip-1]import-route ospf
[r3-ospf-1]import-route rip
[r3]rip
[r3-rip-1]import-route ospf
[r4]ospf 1
[r4-ospf-1]import-route static

5指向1 出问题
一、 使用filter-policy 在RIP侧过滤10.5.5.5的路由
[r2]acl 2000
[r2-acl-basic-2000]rule deny source 10.5.5.5 0
[r2-acl-basic-2000]rule permit
[r2]ip ip-prefix 1 deny 10.5.5.5 32
[r2]ip ip
[r2]ip ip-prefix 1 permit 0.0.0.0 0 less-equal
[r2]rip
[r2-rip-1]filter-policy ip-prefix 1 import
R3同理

二、使用 preference 加 route-policy 精确修改优先级
[r3]ip ip-prefix p index 10 permit 10.5.5.5 32
[r3]route-policy p permit node 10
[r3-route-policy]if-match ip-prefix p
[r3-route-policy]apply preference 160
[r3]rip 1
[r3-rip-1]preference route-policy p
R2同理
