vlan间路由后三层通了，但是VLAN广播隔离；有没有4层通，但是三层隔离的？

第一阶段调试（基础网络配置）：

第一阶段测试：

所有PC都填写IP地址，且都能互通：

第二阶段调试（高级ACL关键配置点）：

SW1：

[SW1]acl advanced 3000

[SW1-acl-ipv4-adv-3000]rule 0 permit ip source 172.16.10.0 0.0.0.255 destination 192.168.1.0 0.0.0.255

[SW1-acl-ipv4-adv-3000]rule 1 permit ip source 172.16.20.0 0.0.0.255 destination 192.168.2.0 0.0.0.255

[SW1-acl-ipv4-adv-3000]rule 3 deny ip source 172.16.10.0 0.0.0.255 destination 192.168.2.0 0.0.0.255

[SW1-acl-ipv4-adv-3000]rule 4 deny ip source 172.16.20.0 0.0.0.255 destination 192.168.1.0 0.0.0.255

[SW1-acl-ipv4-adv-3000]quit

[SW1]int gi 1/0/1

[SW1-GigabitEthernet1/0/1]packet-filter 3000 outbound

[SW1-GigabitEthernet1/0/1]quit

第二阶段测试：

VLAN 10的终端能PING通server1，无法Ping通server2：

Vlan 20的终端能PING通server2，PING不通server1：

Server1能PING通VLAN 10的终端，PING不通VLAN 20的终端：

Server2能PING通VLAN 20的终端，PING不通VLAN 10的终端：

查看ACL的匹配情况：

至此，高级ACL典型组网配置案例已完成！
