1.Change hostname, and secret
Router(config)# hostname xxxx
Router(config)# enable secret xxxx

2.Create a vlan
Switch(config)# vlan _____
Switch(config-vlan)# name _______

3.Assign vlan to a port
Switch(config)#interface______(to device)
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan_________
Switch(config)#interface______(to router)
Switch(config-if)#switchport mode trunk
Switch(config)# show vlan brief

4.Encapsulation router
RTR_STPI(config)#int fa0/0.30(vlan numb)
RTR_STPI(config-subif)#encapsulation dot1Q 30(vlan numb)
RTR_STPI(config-subif)#ip add(default gateway) 255.255.255.0
RTR_STPI(config-subif)#exit

5.Give router ip
Router(config)#int se0/3/0 (router serial)
Router(config-if)#ip add 10.1.1.1 (ip router) 255.255.255.0

6.Route device from router
Router(config)#ip route 192.168.100.0(ip device below router from 0) 255.255.255.0 se0/3/0 (router serial)

7.Give switch ip
Switch(config)#int vlan 10(vlan numb)
Switch(config-if)#ip add 192.168.100.50(ip switch) 255.255.255.0
Switch(config-if)#ex
Switch(config)#ip default-gateway 192.168.100.1
