Konfigurasi Internet Gateway, DHCP, VLAN, Telnet dan SSH menggunakan Cisco Packet Tracer

Desember 04, 2019

Konfigurasi Internet Gateway, DHCP, Vlan, Telnet dan SSH menggunakan Cisco Packet Tracer.

Langkah pertama buatlah topologinya seperti contoh berikut :

Selanjutnya kita konfigurasi router menggunakan console,

Klik PC nya kemudian dekstop setelah itu klik terminal lalu ok

Setelah masuk ke terminal yang pertama kita konfigurasi dhcp terlebih dahulu,

1. Konfigurasi DHCP

Router>en

Router#conf t

Router(config)#ip dhcp pool vlan10

Router(dhcp-config)#default-router 10.10.10.1

Router(dhcp-config)#network 10.10.10.0 255.255.255.0

Router(dhcp-config)#ip dhcp pool vlan20

Router(dhcp-config)#default-router 20.20.20.1

Router(dhcp-config)#network 20.20.20.0 255.255.255.0

Router(config)#ip dhcp pool vlan30

Router(dhcp-config)#default-router 30.30.30.1

Router(dhcp-config)#network 30.30.30.0 255.255.255.0

Router(dhcp-config)#ex

Selanjutnya kita no shutdown kabel yang menyambung ke switch,

Router(config)#int fa0/0
Router(config-if)#no sh

2. Konfigurasi encapsulation

Router(config-if)#int fa0/0.10
Router(config-subif)#encapsulation dot1q 10
Router(config-subif)#ip add 10.10.10.1 255.255.255.0
Router(config-subif)#ex
Router(config)#int fa0/0.20
Router(config-subif)#encapsulation dot1q 20
Router(config-subif)#ip add 20.20.20.1 255.255.255.0
Router(config-subif)#ex
Router(config)#int fa0/0.30
Router(config-subif)#encapsulation dot1q 30
Router(config-subif)#ip add 30.30.30.1 255.255.255.0
Router(config-subif)#ex

3. Konfigurasi Telnet dan SSH

Router(config)#hostname helmi
helmi(config)#ip domain-name helmi.net
helmi(config)#crypto key generate rsa
The name for the keys will be: helmi.helmi.net
Choose the size of the key modulus in the range of 360 to 2048 for your
General Purpose Keys. Choosing a key modulus greater than 512 may take
a few minutes.

How many bits in the modulus [512]: 512 (diisi sesuai yang diminta)
% Generating 512 bit RSA keys, keys will be non-exportable...[OK]

helmi(config)#line vty 0 4
*Mar 1 0:51:30.323: RSA key size needs to be at least 768 bits for ssh version 2
*Mar 1 0:51:30.324: %SSH-5-ENABLED: SSH 1.5 has been enabled
helmi(config-line)#login local
helmi(config-line)#transport input all
helmi(config-line)#exit
helmi(config)#username helmi password 123
helmi(config)#enable secret helmi

4. Konfigurasi NAT/PATH

helmi(config)#access-list 1 permit 0.0.0.0 255.255.255.240
helmi(config)#ip nat inside source list 1 interface fa0/1 overload
helmi(config)#int fa0/1
helmi(config-if)#no sh
helmi(config-if)#ip add 8.8.8.1 255.255.255.240
helmi(config-if)#ex

Selanjutnya kita konfigurasi di switch

5. Konfigurasi Vlan di switch

Switch>en
Switch#conf t
Switch(config)#vlan 10
Switch(config-vlan)#name vlan10
Switch(config-vlan)#vlan 20
Switch(config-vlan)#name vlan20
Switch(config-vlan)#vlan 30
Switch(config-vlan)#name vlan30
Switch(config-vlan)#ex
Switch(config)#int ra fa0/2-8
Switch(config-if-range)#sw mod acc
Switch(config-if-range)#sw acc vlan 10
Switch(config-if-range)#int ra fa0/9-16
Switch(config-if-range)#sw mod acc
Switch(config-if-range)#sw acc vlan 20
Switch(config-if-range)#int ra fa0/17-24
Switch(config-if-range)#sw mod acc
Switch(config-if-range)#sw acc vlan 30
Switch(config-if-range)#ex

6. Konfigurasi trunk
