Configure DHCP between different vlan to realize communication
1, experiment name: configure DHCP between different vlan to realize communication
Experimental purpose: to realize communication with pc0/pc1/pc2/pc3
Lab Topology:
2. Experimental steps:
(1) PC0,PC1,PC2,PC3 IP address is set to DHCP
(2) configure the switch:
Configure switch 1: create VLAN10, and all three interfaces join the VLAN10
Switch (config) # vlan 10
Switch (config-vlan) # exit
Switch (config) # interface fas0/1
Switch (config-if) # switchport mode access
Switch (config-if) # switchport access vlan 10
Switch (config-if) # no shutdown
Switch (config-if) # interface fas0/2
Switch (config-if) # switchport mode access
Switch (config-if) # switchport access vlan 10
Switch (config-if) # no shutdown
Switch (config-if) # interface fas0/3
Switch (config-if) # switchport mode access
Switch (config-if) # switchport access vlan 10
Switch (config-if) # no shutdown
Configure switch 2: create a VLAN20 (the steps are the same as the switch)
(3) configure layer 3 switch:
Switch (config) # vlan 10
Switch (config-vlan) # exit
Switch (config) # interface fas0/1
Switch (config-if) # switchport mode access
Switch (config-if) # switchport access vlan 10
Switch (config) # interface vlan 10
Switch (config-if) # ip address 192.168.10.254 255.255.255.0
Switch (config-if) # no shutdown
Switch (config) # interface fas0/1
Switch (config-if) # ip dhcp pool vlan-10
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
3. Verification and testing
4. Summary of the experiment:
Configuration ideas:
1.PC: IP address is set to DHCP
two。 Switch configuration creates VLAN and adds interfaces to VLAN
3. Configure layer 3 switches:
Create VLAN 10, VLAN 20 and configure static gateways
4. Layer 3 switches configure network segments, gateways, DNS
5. Verification and testing (automatically assigning IP addresses, ping commands)
6 Experimental conclusion: setting DHCP between different VLAN can automatically assign IP address to realize interworking.
