三层架构实验
配置思路: channel->VLAN->Trunk->STP->SVI->Vrrp->DHCP 1、 配置sw1、sw2的channel Sw1: [sw1]interface Eth-Trunk 0 [sw1-Eth-Trunk0]trunkport GigabitEthernet 0/0/1 [sw1-Eth-Trunk0]trunkport GigabitEthernet 0/0/2 Sw2: [sw2]interface Eth-Trunk 0 [sw2-Eth-Trunk0]trunkport GigabitEthernet 0/0/1 [sw2-Eth-Trunk0]trunkport GigabitEthernet 0/0/2 2、 配置sw1、sw2、sw3、sw4的VLAN,并划入接口 Sw1: [sw1]vlan 2 [sw1]interface Eth-Trunk 0 [sw1-Eth-Trunk0]port link-type trunk [sw1-Eth-Trunk0]port trunk allow-pass vlan 2 [sw1]interface g0/0/3 [sw1-GigabitEthernet0/0/3]port hybrid tagged vlan 2 [sw1]interface GigabitEthernet 0/0/4 [sw1
