您好,请知:
默认是会互通的。
VLAN之间不能互访,可以使用高级ACL来实现,以下是配置案例及链接,请参考:
https://zhiliao.h3c.com/Theme/details/102369
组网说明:
本案例采用H3C HCL模拟器来模拟高级ACL典型组网配置。服务器在网络拓扑图中已有明确的标识。要求VLAN 10仅能访问server1,VLAN 20仅能访问server2。R1与SW1运行OSPF路由协议。
1、按照网络拓扑图正确配置IP地址
2、SW1与R1运行OSPF路由协议
3、在SW1配置高级ACL,VLAN 10仅能访问server1,VLAN 20仅能访问server2。
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:
