一、实验拓扑
二、实验简述
R1通过R2来主访问R4的10.0.1.0/32和10.0.3.0/32网段,而R1通过R3来主访问R4的10.0.2.0/32和10.0.4.0/32网段
简易图:
三、实验配置

查看 R1、R4 路由是否已通
去往10.0.1-4.0/32的下一跳
配置控制选路
R1:
acl 3000
rule 5 permit ip source 10.0.11.1 0 destination 10.0.0.0 0.0.254.255
acl 3001
rule permit ip source 10.0.11.1 0 de 10.0.1.0 0.0.254.255
policy-based-route G permit node 1
if-match acl 3000
apply ip-address next-hop 192.168.12.2
policy-based-route G permit node 2
if-match acl 3001
apply ip-address next-hop 192.168.13.3
int g0/0/02
ip policy-based-route G
四、实验验证
没改变之前的选路
