vlan间通信(单臂路由、多臂路由、三层交换)配置命令(思科+华为)

单臂路由

路由器单个接口配置多个子接口，打上vlan标签，模拟三层交换机的vlanif接口功能

描述	思科	华为
创建 VLAN	vlan 10 vlan 20	vlan batch 10 20
设置 Access 接口并指定 VLAN	int f0/1 no shutdown switchport mode access switchport access vlan 10 int f0/2 no shutdown switchport mode access switchport access vlan 20	int e0/1 port link-type access port default vlan 10 int e0/2 port link-type access port default vlan 20
设置 Trunk 接口并允许 VLAN 数据通过	int f0/3 no shutdown switchport mode trunk switchport trunk allow vlan all	int e0/3 port link-type trunk port trunk allow-pass vlan all
路由器设置子接口	int g0/0/0 no shutdown int g0/0/0.1 encapsulation dot1Q 10 ip add 192.168.10.254 255.255.255.0 encapsulation dot1Q 20 ip add 192.168.20.254 255.255.255.0 ip routing	int g0/0/0.10 dot1q termination vid 10 arp broadcast enable ip address 192.168.10.254 24 int g0/0/0.20 dot1q termination vid 20 arp broadcast enable ip address 192.168.20.254 24

多臂路由

路由器多个接口连接交换机，配置作为vlan网关地址，利用路由功能实现不同vlan间通信

描述	思科	华为
创建 VLAN	vlan 10 vlan 20	vlan batch 10 20
设置 Access 接口并指定 VLAN	int f0/1 no shutdown switchport mode access switchport access vlan 10 int f0/2 no shutdown switchport mode access switchport access vlan 20 int f0/3 no shutdown switchport mode access switchport access vlan 10 int f0/4 no shutdown switchport mode access switchport access vlan 20	int e0/1 port link-type access port default vlan 10 int e0/2 port link-type access port default vlan 20 int e0/3 port link-type access port default vlan 10 int e0/4 port link-type access port default vlan 20
设置路由器接口 IP	int g0/0/0 no shutdown ip add 192.168.10.254 255.255.255.0 int g0/0/1 no shutdown ip add 192.168.20.254 255.255.255.0	int g0/0/0 ip add 192.168.10.254 24 int g0/0/1 ip add 192.168.20.254 24

三层交换机

创建vlan接口，配置接口楼地址为vlan网关地址，实现不同vlan间通信

描述	思科	华为
创建 VLAN	vlan 10 vlan 20	vlan batch 10 20
设置 Access 接口并指定 VLAN	int f0/1 no shutdown switchport mode access switchport access vlan 10 int f0/2 no shutdown switchport mode access switchport access vlan 20 int f0/3 no shutdown switchport mode access switchport access vlan 10 int f0/4 no shutdown switchport mode access switchport access vlan 20	int e0/1 port link-type access port default vlan 10 int e0/2 port link-type access port default vlan 20 int e0/3 port link-type access port default vlan 10 int e0/4 port link-type access port default vlan 20
设置 Trunk 接口并允许 VLAN 数据通过	int f0/3 no shutdown switchport mode trunk switchport trunk allow vlan all	int e0/3 port link-type trunk port trunk allow-pass vlan all
设置三层交换机 VLAN 接口	vlan 10 vlan 20 int vlan 10 ip add 192.168.10.254 255.255.255.0 int vlan 20 ip add 192.168.20.254 255.255.255.0	vlan batch 10 20 int vlanif 10 ip add 192.168.10.254 24 int vlanif 20 ip add 192.168.20.254 24
启用 IP 路由	int f0/1 no shutdown ip routing	/
