ENSP DHCP+VLAN间路由通信

大家好，我是讯享网，很高兴认识大家。

要想DHCP获取ip的同时又要两端互相ping通那就得在子接口(g0/0/0.1 g0/0/0.2)上配置dhcp和vlan间路由

第一步：先搭好拓扑图（交换机用二层的，用二层不用配置）

第二步：在AR2进行配置

[AR2]dhcp enable 开启DHCP功能 [AR2]ip pool beijin 配置第一个地址池 Info: It's successful to create an IP address pool. [AR2-ip-pool-beijin]net 192.168.10.0 mask 24 [AR2-ip-pool-beijin]dns-list 192.168.10.254 [AR2-ip-pool-beijin]gateway-list 192.168.10.1 [AR2-ip-pool-beijin]q [AR2]ip pool shanghai 配置第二个地址池 Info: It's successful to create an IP address pool. [AR2-ip-pool-shanghai]net 192.168.20.0 mask 24 [AR2-ip-pool-shanghai]dns-list 192.168.20.254 [AR2-ip-pool-shanghai]gateway-list 192.168.20.1 [AR2-ip-pool-shanghai]q [AR2-GigabitEthernet0/0/0.1]dot1q termination vid 10 VLAN间路由两个端口都要配 [AR2-GigabitEthernet0/0/0.1]ip address 192.168.10.1 255.255.255.0 [AR2-GigabitEthernet0/0/0.1]arp broadcast enable [AR2-GigabitEthernet0/0/1.1]dot1q termination vid 20 [AR2-GigabitEthernet0/0/1.1ip address 192.168.20.1 255.255.255.0 [AR2-GigabitEthernet0/0/1.1]arp broadcast enable [AR2]int g0/0/0.1 [AR2-GigabitEthernet0/0/0.1]dhcp select global 直接全局应用他好像自动识别1,2的就是你先创pool的循序来应用的 [AR2-GigabitEthernet0/0/0.1]int g0/0/1.1 [AR2-GigabitEthernet0/0/1.1]dhcp select global

[AR2-ip-pool-beijin]excluded-ip-address 192.168.10.254 他可以禁止已用过的ip进行二次分配

交换机上的配置LW3 、LW4

讯享网[LW3]vlan batch 10 20 [LW3]interface Ethernet0/0/1 [LW3-Ethernet0/0/1]port link-type access [LW3-Ethernet0/0/1]port default vlan 10 [LW3]interface Ethernet0/0/2 [LW3-Ethernet0/0/2]port link-type access [LW3-Ethernet0/0/2]port default vlan 10 [LW3]interface Ethernet0/0/3 [LW3-Ethernet0/0/3]port link-type trunk [LW3-Ethernet0/0/3]port trunk allow-pass vlan 10 20 连路由的交换机的线路都要配置trunk [LW4]vlan batch 10 20 [LW4]interface Ethernet0/0/2 [LW4-Ethernet0/0/2]port link-type access [LW4-Ethernet0/0/2]port default vlan 20 [LW4]interface Ethernet0/0/3 [LW4-Ethernet0/0/3]port link-type access [LW4-Ethernet0/0/3]port default vlan 20 [LW4]interface Ethernet0/0/1 [LW4-Ethernet0/0/1port link-type trunk [LW4-Ethernet0/0/1]port trunk allow-pass vlan 10 20 连路由的交换机的线路都要配置trunk

在pc端调成DHCP模式将其应用

查看配置结果（刚刚吧254 排除掉了所以他从253开始分配）
