一、单臂路由1.1概念
单臂路由实现不同vlan之间通信
1.2链路类型
access链路:交换机连接主机的端口
trunk链路:交换机连接路由器的端口
hybrid链路:华为
1.3子接口
路由的物理接口可以被划分为多个逻辑接口
每个子接口对应一个vlan网段的网关
1.4单臂路由的配置
(1)配置链路类型
(2)配置vlan标签的封装结构
(3)配置子接口地址

实验代码:
SW1:
vlan batch 10 20
port-group 1
group-member g0/0/1 to g0/0/2
port link-type access
port default vlan 10
q
port-group 2
group-member g0/0/3 to g0/0/4
port link-type access
port default vlan 20
q
port-group 3
group-member g0/0/5 to g0/0/6
port link-type trunk
port trunk allow-pass vlan all
SW2:
vlan batch 10 20
int g0/0/1
port link-type trunk
port trunk allow-pass vlan all
int g0/0/2
port link-type access
port default vlan 10
int g0/0/3
port link-type access
port default vlan 20
AR1:
int g0/0/0.10
dotlq termination vid 10
ip add 192.168.10.1 24
arp broadcast enable
int g0/0/0.20
dotlq termination vid 120
ip add 192.168.20.1 24
arp broadcast enable
二、三层交换(选型失败使用)2.1三层交换技术
使用三层交换技术实现vlan间通讯
三层交换=二层交换+三层转发
2.2三层交换机实现vlan间通信
