eNSP中實現vlan間路由通信（路由器）
拓撲圖
PC配置
pc1：192.168.10.1255.255.255.0192.168.10.254pc2：192.168.20.1255.255.255.0192.168.20.254pc3：
192.168.10.2255.255.255.0192.168.10.254pc4:192.168.20.2255.255.255.0192.168.20.254
交換機配置
LSW1：
[Huawei]vlan batch vlan 10 20[Huawei]int Eth0/0/1[Huawei-Ethernet0/0/1]port link-type access[Huawei-Ethernet0/0/1]port default vlan 10[Huawei]int Eth0/0/2[Huawei-Ethernet0/0/2]port link-type access[Huawei-Ethernet0/0/2]port default vlan 20[Huawei]int Eth0/0/3[Huawei-Ethernet0/0/3]port link-type trunk[Huawei-Ethernet0/0/3]port default vlan 10 20<Huawei>save
LSW2：
[Huawei]vlan batch vlan 10 20[Huawei]int Eth0/0/1[Huawei-Ethernet0/0/1]port link-type access[Huawei-Ethernet0/0/1]port default vlan 10[Huawei]int Eth0/0/2[Huawei-Ethernet0/0/2]port link-type access[Huawei-Ethernet0/0/2]port default vlan 20[Huawei]int Eth0/0/3[Huawei-Ethernet0/0/3]port link-type trunk[Huawei-Ethernet0/0/3]port default vlan 10 20<Huawei>save
LSW3配置三個trunk口就行了：
[Huawei]vlan batch vlan 10 20[Huawei]int Eth0/0/1[Huawei-Ethernet0/0/1]port link-type trunk[Huawei-Ethernet0/0/1]port trunk allow-pass vlan 10 20[Huawei]int Eth 0/0/2[Huawei-Ethernet0/0/2]port link-type trunk[Huawei-Ethernet0/0/2]port trunk allow-pass vlan 10 20[Huawei]int Eth0/0/3 [Huawei-Ethernet0/0/3]port link-type trunk[Huawei-Ethernet0/0/3]port trunk allow-pass vlan 10 20<Huawei>save
路由器配置：
這里要注意了，在ensp里面，路由器默認是開啟二層接口，但是二層接口是配置不了子接口的，因此需要開啟三層接口
[Huawei]undo portswitch //開啟三層接口[Huawei]int Eth0/0/0.10[Huawei-Ethernet0/0/0.10]ip address 192.168.10.254 255.255.255.0 //配置網關[Huawei-Ethernet0/0/0.10]dot1q termination vid 10 //封裝子接口[Huawei-Ethernet0/0/0.10]arp broadcast enable //開啟子接口的ARP廣播（必須）[Huawei]int Eth0/0/0.20[Huawei-Ethernet0/0/0.20]ip address 192.168.20.254 255.255.255.0[Huawei-Ethernet0/0/0.20]dot1q termination vid 20[Huawei-Ethernet0/0/0.20]arp broadcast enable [Huawei]int Eth0/0/0[Huawei-Ethernet0/0/0]undo shutdown //開啟主接口<Huawei>save
測試
pc1和pc2：
pc1和pc3：
pc1和pc4：
四臺主機全部成功互相通信。
總結
還是一樣的，可以去cisco抓包觀察原理，不同廠商的命令行配置不同是正常的，知道原理后一切都迎刃而解了。
