使用 preference 加 route-policy 精确修改优先级，修改完优先级后过滤
r2

[R2]ip ip-prefix p index 10 permit 10.5.5.5 32 //使用前缀列表匹配10.5.5.5/32的流量
[R2]route-policy p permit node 1		//路由策略P允许通过
[R2-route-policy]if-match ip-prefix p	//如果匹配使用前缀列表P
[R2-route-policy]apply preference 160
[R2]route-policy p permit node 20		//允许其他路由通过
[R2-route-policy]rip 1 					//在rip下配置路由策略
[R2-rip-1]preference route-policy p

r3

[R3]ip ip-prefix p index 10 permit 10.5.5.5 32
[R3]route-policy p permit node 1
[R3-route-policy]if-match ip-prefix p
[R3-route-policy]apply preference 160
[R3]route-policy p permit node 20
[R3-route-policy]rip 1
[R3-rip-1]preference route-policy p

使用filter-policy 在RIP侧过滤10.5.5.5的路由
r2

[R2]ip ip-prefix p deny 10.5.5.5 32
[R2]rip 1
[R2-rip-1]filter-policy ip-prefix p import 	//过滤前缀列表P流量进入

r3

[R3]rip 1
[R3-rip-1]filter-policy ip-prefix p import 
[R3]ip ip-prefix p deny 10.5.5.5 32
