1. Experimental Requirements

PC1belong toVlan10,PC2belong toVlan20,PC3belong toVlan30,PC4belong toVlan10.

Use DHCP automatically get IP address.

The use of single-arm routing technology to achieve full network interoperability.

2. Experimental Steps

      

R1 :

R1#conf T

Enterconfiguration commands, one per line. End with cntl/z.

R1 (config) #intfa0/0

R1 (config-if) #noshutdown turn the interface fa0/0 on

R1 (config-if) #intfa0/0.10 Input sub-interface

R1 (config-subif) #encapsulationdot1Q Change the package type of the interface, do vlan10 Gateway

R1 (config-subif) #ipadd 192.168.10.1 255.255.255.0 Configure IP address

R1 (config-subif) #noshut

R1 (config-subif) #intfa0/0.20

R1 (config-subif) #encapsulationdot1Q 20

R1 (config-subif) #ipadd 192.168.20.1 255.255.255.0

R1 (config-subif) #noshut

R1 (CONFIG-SUBIF) #intfa0/0.30

R1 (config-subif) #encapsulationdot1Q 30

R1 (config-subif) #ipadd 192.168.30.1 255.255.255.0

R1 (config-subif) #noshut

R1 (config-subif) #exit

R1 (config) to establish a DHCP address pool #ipdhcp Pool V10

R1 (Dhcp-config) #network192.168.10.0/24

R1 (dhcp-config) #default-router192.168.10.1

R1 (dhcp-config) #dns-server1.1.1.1

R1 (Dhcp-config) #exit

R1 (config) to establish a DHCP address pool #ipdhcp Pool V20

R1 (Dhcp-config) #network192.168.20.0/24

R1 (dhcp-config) #default-router192.168.20.1

R1 (dhcp-config) #dns-server2.2.2.2

R1 (Dhcp-config) #exit

R1 (config) to establish a DHCP address pool #ipdhcp pool V30

R1 (Dhcp-config) #network192.168.30.0/24

R1 (dhcp-config) #default-router192.168.30.1

R1 (dhcp-config) #dns-server3.3.3.3

R1 (Dhcp-config) #exit

SW1:

Sw1#conft

SW1 (config) #no IP routing off routing feature

SW1 (config) #vlan 10,20,30 to establish vlan10,20,30,

SW1 (Config-vlan) #int fa1/0

SW1 (config-if) #switchport access VLAN joins the interface into the VLAN

SW1 (config-if) #int FA1/1

SW1 (config-if) #switchport Access VLAN 20

SW1 (config-if) #int FA1/15

SW1 (config-if) #switchport mode trunk to turn the interface into a relay port

SW1 (config-if) #int FA1/4

SW1 (config-if) #switchport mode trunk to turn the interface into a relay port

SW2:

Sw2#conft

SW2 (config) #no IP routing off routing feature

SW2 (Config-vlan) #vlan 10,20,30 established vlan10,20,30

SW2 (Config-vlan) #int FA1/2

SW2 (config-if) #switchport access VLAN add interface to VLAN

SW2 (config-if) #int FA1/3

SW2 (config-if) #switchport Access VLAN 10

SW2 (config-if) #int FA1/15

SW2 (config-if) #switchport mode trunk to turn the interface into a relay port
