Jika kita ingin membuat IP DHCP di Segment LAN, maka kita perlu menambahkan command berikut :

Ket : dns-server : bisa juga di isikan DNS Public

BOGOR (config)#ip dhcp pool LAN1

BOGOR (dhcp-config)#network 192.168.30.0 255.255.255.240

BOGOR (dhcp-config)#dns-server 192.168.30.1

BOGOR (dhcp-config)#default-router 192.168.30.1

BOGOR (dhcp-config)#exit

BOGOR (config)#ip dhcp pool LAN2

BOGOR (dhcp-config)#network 192.168.40.0 255.255.255.240

BOGOR (dhcp-config)#dns-server 192.168.40.1

BOGOR (dhcp-config)#default-router 192.168.40.1

BOGOR (dhcp-config)#exit

ROUTING OSPF BOGOR

BOGOR (config)#router ospf 100

BOGOR (config-router)#network 172.16.2.0 0.0.0.3 area 0

BOGOR (config-router)#network 192.168.30.0 0.0.0.15 area 0

BOGOR (config-router)#network 192.168.40.0 0.0.0.15 area 0

Lalu kita setting switchnya, langkah-langkahnya sebagai berikut :

Definisikan Vlan :

Switch#vlan database

Switch(vlan)#vlan 10 name LAN 1

Switch(vlan)#vlan 20 name LAN 2

Delegasikan port untuk mengakses tiap-tiap Vlan yang sudah didefinisikan :

Switch>enable

Switch#configure terminal

Switch(config)#interface fa0/1 -> Menuju router

Switch(config-if)#switchport mode trunk

Switch(config-if)#exit

Switch(config)#interface fa0/2 -> Menuju LAN 1

Switch(config-if)#switchport access vlan 10

Switch(config-if)#exit

Switch(config)#interface fa0/3 -> Menuju LAN 2

Switch(config-if)#switchport access vlan 20

Switch(config-if)#exit
