H3C 三层交换实验

实验拓扑

​​

实验需求

1. 按照图示为 PC1 和 PC2 配置 IP 地址和网关
2. PC1 属于 Vlan10，PC2 属于 Vlan20，在三层交换机上配置 Vlanif 三层接口实现 Vlan10 和 Vlan20 三层互通
3. PC1 和 PC2 可以互通

实验步骤

PC配置IP地址（略）

SW1配置

创建VLAN10和VLAN20

#
vlan 10
#
vlan 20

将VLAN加入到对应接口

#
interface GigabitEthernet1/0/1
 port link-mode bridge
 port access vlan 10
#
interface GigabitEthernet1/0/2
 port link-mode bridge
 port access vlan 20

配置Vlanif接口

#
interface Vlan-interface10
 ip address 192.168.1.254 255.255.255.0
#
interface Vlan-interface20
 ip address 192.168.2.254 255.255.255.0

实验验证

在 SW1 上查看路由表，会发现已经产生了到达192.168.1.0/24网段和192.168.2.0/24网段的直连路由，出接口分别指向各自 Vlanif 接口，证明 SW1 已经可以对 Vlan10 和 Vlan20 间的数据进行三层转发
