H3C 单臂路由实验

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，配置单臂路由实现 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）

配置单臂路由实现 Vlan10 和 Vlan20 三层互通

用单臂路由实现 Vlan 间三层互通，需要把 SW2 连接 R1 的接口配置为 Trunk，并允许 Vlan10 和 Vlan20 通过，R1 连接 SW2 的接口上要开启子接口，分别作为 Vlan10 和 Vlan20 的网关。

SW1 配置

创建VLAN10和VLAN20

#
vlan 10
#
vlan 20

G1/0/1和G1/0/2分别加入VLAN10和VLAN20

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

G1/0/3 Trunk 放行VLAN10和VLAN20

#
interface GigabitEthernet1/0/3
 port link-mode bridge
 port link-type trunk
 undo port trunk permit vlan 1
 port trunk permit vlan 10 20

R1 配置

创建G0/0.1子接口，配置网关IP地址，开启 dot1q 识别，绑定VLAN10

#
interface GigabitEthernet0/0.1
 ip address 192.168.1.254 255.255.255.0
 vlan-type dot1q vid 10

‍

创建G0/0.2子接口，配置网关IP地址，开启 dot1q 识别，绑定VLAN20

#
interface GigabitEthernet0/0.2
 ip address 192.168.2.254 255.255.255.0
 vlan-type dot1q vid 20

实验验证

在 R1 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子接口，证明路由器已经可以对 Vlan10 和 Vlan20 间的数据进行三层转发
