Lab Environment:
Routers make Tp-link set up NAT forwarding, Tp-link router gateway is set to 192.168.30.254
( core layer) Cisco 35,503 layer switch (model C3550-I5Q3L2-M) configuration three Vlan,vlan 10, VLAN 20, and VLAN 30
IP address for VLAN 10:192.168.10.1/24
IP address for VLAN 20:192.168.20.1/24
FA0/24 ports are configured as trunk port-level converged layer Cisco 2960 switch FA0/24 ports through VLAN 10 and VLAN 20
IP address for VLAN 30:192.168.30.1/24 is mainly used for connecting with Tp_link routers, setting up static route forwarding use, using FA0/23 port
( aggregation layer) Cisco 29,602-Layer Switching (model WS-C2960S-24TS-L) machine configuration two Vlan,vlan 10 and VLAN 20
callout:ga 1/0/1-5 Meaning: 1 for the first slot, 0 for the 0 slot on the card, and 1-5 for the port on the slot.
VLAN 10 divides the GI 1/0/1-5 port
VLAN 20 divides the GI 1/0/6-10 port
Gi 1/0/24 port configured as Trunk Port Cascade core layer Cisco 3550 Switch FA0/24 port through transmission VLAN 10 and VLAN 20
Gi 1/0/1 port Access DHCP server
( access layer) Tp-link SG 1024T Switch
Implementation features:
1, VLAN 10 and VLAN 20 can access each other.
2, the computer can automatically get the DHCP server to assign different VLAN IP address.
3, the computer can sisu net
##### #Cisco 3550 three-layer switch operation step ######
1. Create VLAN 10 and VLAN 20
#特权模式下进入VLAN子模式
switch#VLAN Database

#VLAN 10 assigning IP addresses and gateways, 192.168.10.1 is the gateway for VLAN 10
Switch (config-if) #IP address 192.168.10.1 255.255.255.0
#退出
Switch (config-if) #Exit
#全局模式下进入VLAN 20
Switch (config) #interface VLAN
#VLAN 20 assigning IP addresses and gateways, 192.168.10.1 is the gateway for VLAN 20
Switch (config-if) #IP address 192.168.20.1 255.255.255.0
#退出
Switch (config-if) #Exit
#特权模式下查看当前配置信息
switch#Show Running-config
3. Turn on the three layer switch routing function
#全局模式下开启路由后VLAN can access each other.
Switch (config) #IP Routing
#特权模式下查看路由表
switch#show ip route
#特权模式下保存配置
switch#Write
4. VLAN Configuration DHCP Relay Agent
#全局模式下进入VLAN 10
Switch (config) #interface VLAN
#配置VLAN 10 Relay Agent, 192.168.10.200 is the DHCP server address
Switch (config-if) #IP helper-address 192.168.10.200
#退出VLAN 10
Switch (config-if) #Exit
#全局模式下进入VLAN 20
Switch (config) #interface VLAN
#配置VLAN 20 Relay Agent, 192.168.10.200 is the DHCP server address
Switch (config-if) #IP helper-address 192.168.10.200
#退出VLAN 20
Switch (config-if) #Exit
5. Set FA0/24 port to trunk port
switch#Show Interfaces fastethernet 0/24 Switchport
Name:fa0/24
Switchport:enabled
Administrative mode: dynamic desirable #三层交换机端口默认dynamic desirable do not have to set the trunk port, this mode will automatically adapt to the peer port operation mode
Operational Mode: trunk
6. Set up the static route forwarding router to realize the Internet
#特权模式下进入VLAN子模式
switch#VLAN Database
#VLAN 30 named Route30
Switch (VLAN) #VLAN-name Route30
#退出
Switch (VLAN) #Exit
#全局模式下进入VLAN 30
Switch (config) #interface VLAN
#VLAN 30 Configuring the IP address and gateway, 192.168.30.1 is the gateway for VLAN 30
Switch (config-if) #IP address 192.168.30.1 255.255.255.0
#退出
Switch (config-if) #Exit
#全局模式下进入fa0/23 Ports
Switch (config) #interface fastethernet 0/23
#fa0/23 Ports assigned to VLAN 30
Switch (config-if) #switchport access VLAN
#激活端口
Switch (config-if) #no shutdown
#全局模式下设置静态路由转发, 192.168.30.254 is the Tp-link router gateway
Switch (config) #IP route 0.0.0.0 0.0.0.0 192.168.30.254
