实验要求
1.搭建拓扑
路由策略分析：
拓扑左边是rip协议，右边是ospf协议，想要实现全网可达可以采用多点双向重发布的方式。
对于rip协议使用偏移列表来干涉选路，对于ospf协议采用路由策略来干涉选路
2.配置ip

r4
[AR4]ospf 1 router-id 4.4.4.4
[AR4-ospf-1]area 0
[AR4-ospf-1-area-0.0.0.0]network 24.0.0.2 0.0.0.0
[AR4-ospf-1-area-0.0.0.0]network 34.0.0.2 0.0.0.0
[AR4-ospf-1-area-0.0.0.0]network 192.168.4.1 0.0.0.0
5.双向重发布
r2
[AR2]rip 1
[AR2-rip-1]import-route ospf 1
[AR2]ospf 1
[AR2-ospf-1]import-route rip
[AR2]ospf 1
[AR2-ospf-1]import-route rip 1 route-policy A
r3
[AR3]rip 1
[AR3-rip-1]import-route ospf 1
[AR3]ospf 1
[AR3-ospf-1]import-route rip
6.路由策略
r2
[AR2]route-policy A permit node 10
[AR2-route-policy]if-match ip-prefix A
[AR2-route-policy]apply cost-type type-1 #修改A表中node节点流量的属性
[AR2]route-policy A permit node 20
[AR2-route-policy]if-match ip-prefix A
[AR2-route-policy]apply cost-type type-1 #修改A表中node节点流量的属性
[AR2]route-policy A permit node 30 #定义空列表，允许其他流量访问
[AR2]ip ip-prefix A index 10 permit 192.168.2.0 24 # 定义要抓取的流量
[AR2]ip ip-prefix A index 20 permit 12.0.0.0 24
r3
[AR3]ip ip-prefix A permit 13.0.0.0 24 #定义要抓取的流量
[AR3]route-policy A permit node 10
[AR3-route-policy]if-match ip-prefix A
[AR3-route-policy]apply cost-type type-1 #对抓取的流量修改属性
[AR3]route-policy A permit node 50 #定义空列表，允许让其他流量通过
