Single-arm routing

VLAN planning
Configuration on Switch 0:
switch>en
Switch (config) #vlan 2 #创建vlan2
Switch (config) #vlan 3 #创建vlan3
Switch (Config-vlan) #exit
Switch (config) #exit
Switch#show VLAN #查看vlan

Switch (config) #interface range F0/2-F0/4 #range可以批量选择端口
Switch (config-if-range) #switchport ACC VLAN 2 #将这3个端口添加到vlan2里面
Switch (Config-if-range) #exit
Switch (config) #exit
Switch#show VLAN #查看vlan, the following 2, 3, 4 interfaces have been added
。。。。。。。。。
。。。。。。。。。
2 VLAN0002 Active FA0/2, FA0/3, FA0/4
。。。。。。。
。。。。。。。

Configuration on Switch 1:
switch>en
Switch#configure Terminal
Switch (config) #interface range F0/2-F0/4 #添加range可以批量选择端口
Switch (config-if-range) #switchport ACC VLAN 2 #将f0/2-F0/4 added to VLAN 2

To remove a VLAN step:
switch>en
Switch#conf Terminal
Switch (config) #int range f0/2-4
Switch (config-if-range) #no switchport access VLAN 2 #先把vlan 2 interface removal
Switch (Config-if-range) #exit
Switch (config) #no int vlan 2 #然后再删除vlan 2

Switch (config) #vlan 3 #创建vlan 3
Switch (config) #int range f0/2-4 #选定一个范围
Switch (config-if-range) #switchport access VLAN 3 #把选定范围内的接口添加到vlan 3
Switch#show VLAN #查看vlan和接口, notice where

R1
Router>enable
Router#configure Terminal
Router (config) #interface gigabitethernet 0/0
Router (config-if) #ip add 192.168.0.11 255.255.255.0
Router (config-if) #no shutdown #开启GigabitEthernet 0/0 interface
Router (config-if) #exit
Router (config) #interface gigabitethernet 0/1
Router (config-if) #ip add 192.168.1.11 255.255.255.0
Router (config-if) #no shutdown
Router (config-if) #exit
Router (config) #exit
Router#show IP int Brief

The above is a step to assign IP and VLAN partitioning to each interface
#################################################################

The following open sub-interface, before opening the int g0/0 and G0/1 interface on the address removed. Remember!!!!
Router#sh int g0/0
Router#conf T
Router (config) #int g0/0
Router (config-if) #no IP Add (IP address) #删除几口上的ip地址
-----------------------------------------------------------------

R1 turn on the g0/0 sub-interface:
Router#conf Terminal
Router (config) #int g0/0.10
Router (config-subif) #encapsulation dot1q 3 #3表示是vlan 3
Router (config-subif) #ip addr 192.168.0.11 255.255.255.0
Router (config-subif) #exit

R1 turn on the G0/1 sub-interface:
Router (config) #int g0/1.10 #开启子接口
Router (config-subif) #encapsulation dot1q 2 #把vlan2封装成802.1Q Virtual LAN Protocol
Router (config-subif) #ip addr 192.168.1.11 255.255.255.0
Router (config-subif) #exit
Router (config) #exit

Router left switch
switch>en
Switch#configure Terminal
Switch (config) #interface F0/1
Switch (config-if) #switchport mode trunk

The switch on the right side of the router is the same as the switch on the left, and the router-connected line is changed to trunk.
Switch#configure Terminal
Switch (config) #int F0/1
Switch (config-if) #switchport mode trunk
Router#sh Running-config #查看各个接口的状态

###### #删除子接口 ##########
router# conf t
Router (config) #no int g0/1.20
Router (config) #exit
###### #删除子接口 ##########
