nat
[R1]acl 2000
[R1-acl-basic-2000]rule 5 permit source 192.168.1.0 0.0.0.255
[R1-acl-basic-2000]rule 10 permit source 192.168.2.0 0.0.0.255
R1]interface g0/0/2
[R1-GigabitEthernet0/0/2]nat outbound 2000
[R1-GigabitEthernet0/0/2]int g4/0/0
[R1-GigabitEthernet4/0/0]nat outbound 2000
测试网络是否可达
在接口上抓包发现走的是g0/0/2口
配置路由策略
[R1]acl 2010
[R1-acl-basic-2010]rule 5 permit source 192.168.1.0 0.0.0.255
[R1-acl-basic-2010]q
[R1]acl 2020

流分类
[R1]traffic classifier jiaoxue
[R1-classifier-jiaoxue]if-match acl 2010
[R1-classifier-jiaoxue]q
[R1]traffic classifier bangong
[R1-classifier-bangong]if-match acl 2020
流行为
[R1]traffic behavior dianxin
[R1-behavior-dianxin]redirect ip-nexthop 12.1.1.2
[R1]traffic behavior liantong
[R1-behavior-liantong]redirect ip-nexthop 13.1.1.2
流策略
[R1]traffic policy p
[R1-trafficpolicy-p]classifier jiaoxue behavior dianxin
[R1-trafficpolicy-p]q
[R1]traffic policy q

应用接口
[R1]interface g0/0/0
[R1-GigabitEthernet0/0/0]traffic-policy p inbound
[R1-GigabitEthernet0/0/0]int g0/0/1
[R1-GigabitEthernet0/0/1]traffic-policy q inbound
测试流量路径
在pc1上面看看流量路径是怎么走的
关闭g0/0/2口，流量都走下面接口
R1]int g0/0/2
[R1-GigabitEthernet0/0/2]shutdown
