一、拓扑:
二、配置思路:
1、AR1、2 起 eth-trunk X(AR系列中,X范围0-7)
2、改变接口由二层到三层
3、配置 Porttrunk 范围
4、起三层地址
三、配置内容:
[AR1]:
interface Eth-Trunk0undo portswitchip address 10.1.12.1 255.255.255.0
#
interface GigabitEthernet0/0/0eth-trunk 0
#
interface GigabitEthernet0/0/1eth-trunk 0
#[AR2]
interface Eth-Trunk0trunkport G0/0/0 0/0/2undo portswitchip address 10.1.12.1 255.255.255.0
#
