1. Lab name: layer 3 switch turns on DHCP

2. Experimental purpose: turn on DHCP to obtain IP address automatically

3. Implement the topology:

4. Experimental steps:

Switch (config-vlan) # vlan 30

Switch (config-vlan) # vlan 40

Switch (config-vlan) # int range f0max 6 Magi f0max 3 Magi f0max 5

(4) SW1:

Switch (config) # vlan 10

Switch (config-vlan) # vlan 20

Switch (config-vlan) # vlan 30

Switch (config-vlan) # vlan 40

Switch (config-vlan) # int range f0max 6 Magi f0max 5 Magi f0max 3

Switch (config-if-range) # sw mo tr

(5) Multilayer switch configuration

1) create VLAN10 20 30 40 and enable route forwarding to configure trunk links for lower-layer ports

Switch > en

Switch#conf

Switch (config) # vlan 10

Switch (config-vlan) # vlan 20

Switch (config-vlan) # vlan 30

Switch (config-vlan) # vlan 40

Switch (config-vlan) # exit

Switch (config) # ip routing

Switch (config) # int range f0and6 int range f0and7

Switch (config-if-range) # sw tr e d

Switch (config-if-range) # sw mo tr

2) configure the DHCP address pool corresponding to VLAN10-40 (IP, default gateway, DNS)

Switch (config) # ip dhcp pool vlan10

Switch (dhcp-config) # network 192.168.10.0 255.255.255.0

Switch (dhcp-config) # default-router 192.168.10.254

Switch (dhcp-config) # dns-server 8.8.8.8

Switch (dhcp-config) # e

Switch (config) # ip dhcp pool vlan20

Switch (dhcp-config) # network 192.168.20.0 255.255.255.0

Switch (dhcp-config) # default-router 192.168.20.254

Switch (dhcp-config) # dns-server 8.8.8.8

Switch (dhcp-config) # e

Switch (config) # ip dhcp pool vlan30

Switch (dhcp-config) # network 192.168.30.0 255.255.255.0

Switch (dhcp-config) # default-router 192.168.30.254

Switch (dhcp-config) # dns-server 8.8.8.8

Switch (dhcp-config) # e

Switch (config) # ip dhcp pool vlan40

Switch (dhcp-config) # network 192.168.40.0 255.255.255.0

Switch (dhcp-config) # default-router 192.168.40.254

Switch (dhcp-config) # dns-server 8.8.8.8

Switch (dhcp-config) # e

Switch (config) # service DHCP

3) Virtual interface VLAN configuration corresponds to gateway address

Switch (config) # int vlan 10

Switch (config-if) # ip add 192.168.10.254 255.255.255.0

Switch (config-if) # no shu

Switch (config-if) # int vlan 20

Switch (config-if) # ip add 192.168.20.254 255.255.255.0

Switch (config-if) # no shu

Switch (config-if) # int vlan 30

Switch (config-if) # ip add 192.168.30.254 255.255.255.0

Switch (config-if) # no shu

Switch (config-if) # int vlan 40

Switch (config-if) # ip add 192.168.40.254 255.255.255.0

Switch (config-if) # no shu

Switch (config-if) # end

5. Verification and testing:

6. Summary: configuration ideas:

(1) four PCs set up DHCP to obtain IP addresses automatically

(2) the layer 2 switch creates VLAN 10 20 30 40, and adds the corresponding port access to the corresponding VLAN, and the remaining ports trunk

(3) the layer 2 switch creates VLAN 10pm 20 30 40 trunk and allows all VLAN to pass through

(4) the layer 3 switch enables the routing function. The corresponding two ports trunk and configure the gateway address corresponding to the virtual VLAN 10-40.

(5) layer 3 switch configures VLAN10-40 address pool, gateway, DNS, and enables DHCP in global mode.
