1. Obtaining ip address from a
different network Dhcp Server

3. Configuring Cisco router 2611xm with two
different vlan’s
 R1#config t
 Enter configuration commands, one per line. End with CNTL/Z.
 R1(config)#int fa0/0
 R1(config-if)#no ip address
 R1(config-if)#shutdown
 R1(config-if)#exit
 R1(config)#int fa0/0.1
 R1(config-subif)#encapsulation dot1Q 2
 R1(config-subif)#ip address 192.168.1.1 255.255.255.0
 R1(config-subif)#no shutdown
 R1(config-subif)#exit
 R1(config)#int fa0/0.2
 R1(config-subif)#encapsulation dot1Q 3
 R1(config-subif)#ip address 192.168.2.1 255.255.255.0
 R1(config-subif)#no shutdown
 R1(config-subif)#exit

4. Configuring Cisco switch 2950 with two different
vlan’s
 Switch#config t
 Enter configuration commands, one per line. End with CNTL/Z.
 Switch(config)#vlan 2
 Switch(config-vlan)#exit
 Switch(config)#vlan 3
 Switch(config-vlan)#exit
 Switch(config)#int fa0/21
 Switch(config-if)#switchport mode access
 Switch(config-if)#switchport access vlan 2
 Switch(config-if)#exit
 Switch(config)#int fa0/9
 Switch(config-if)#switchport mode access
 Switch(config-if)#switchport access vlan 2
 Switch(config-if)#exit
 Switch(config)#int fa0/18
 Switch(config-if)#switchport mode trunk
 Switch(config-if)#switchport trunk allowed vlan all

5. Creating int fa0/0.2 of router with ip helper
address
 R1#config t
 Enter configuration commands, one per line. End with CNTL/Z.
 R1(config)#int fa0/0.1
 R1(config-subif)#ip helper-address 192.168.1.2
