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

2.3例子

port link-type access

port default vlan 20

int e0/0/3

port link-type access

port default vlan 30

int e0/0/4

port link-type trunk

int g0/0/2

port link-type access

port default vlan 100

q

ip route-static 192.168.5.0 24 192.168.4.2

AR1

ip add 192.168.4.2 24

int g0/0/1

ip add 192.168.5.254

q

ip route-static 192.168.1.0 24 192.168.4.1

ip route-static 192.168.2.0 24 192.168.4.1
