acl一：使用基本ACL进行数据过滤
实验目的：
部署基本ACL实现数据过滤
实现PC1无法访问PC
拓扑如图所示：（1）在AR1上配置如下：
sys[Huawei]sysname AR1[AR1]int g0/0/0[AR1-GigabitEthernet0/0/0]ip add 192.168.1.254 24 //配置端口IP[AR1-GigabitEthernet0/0/0]int g0/0/1[AR1-GigabitEthernet0/0/1]ip add 192.168.3.1 24[AR1]rip //使用动态路由协议RIP[AR1-rip-1]version 2 //RIP版本为RIPv2[AR1-rip-1]network 192.168.1.0 //宣告192.168.1.0网段[AR1-rip-1]network 192.168.3.0 //宣告192.168.3.0网段（2）在AR2上配置如下：sys[Huawei]un in en[Huawei]sysname AR2[AR2]int g0/0/1[AR2-GigabitEthernet0/0/1]ip add 192.168.3.2 24[AR2-GigabitEthernet0/0/1]int g0/0/2[AR2-GigabitEthernet0/0/2]ip add 192.168.4.2 24[AR2-GigabitEthernet0/0/1]int g0/0/0 [AR2-GigabitEthernet0/0/0]ip add 192.168.2.254 24[AR2]rip[AR2-rip-1]version 2[AR2-rip-1]net 192.168.2.0[AR2-rip-1]net 192.168.3.0[AR2-rip-1]net 192.168.4.0（3）在AR3上配置如下：[Huawei]int g0/0/0[Huawei-GigabitEthernet0/0/0]ip add 192.168.4.3 24[Huawei-GigabitEthernet0/0/0]int g0/0/1[Huawei-GigabitEthernet0/0/1]ip add 192.168.5.254 24[Huawei]rip [Huawei-rip-1]version 2[Huaw
如图即可
