Contoh Kasus Konfigurasi Router (Dengan Packet Tracer)

Konfigurasi komputer
•    Komputer 1:
      IP address    192.168.1.1
      Netmask    255.255.255.0
      Gateway    192.168.1.100
      PC Name    jupiter
•    Komputer 2
      IP address    10.10.10.1
      Netmask    255.0.0.0
      Gateway    10.10.10.100
      PC Name    jupiter

Konfigurasi Router beserta Switch:
•    Router yang digunakan adalah jenis 2620 XM dengan penambahan satu serial port
•    Switch yang digunakan adalah 2950-24

Setelah computer terhubung pada router dan switch, silahkan lakukan koneksi dengan menggunakan test ping, apakah computer dengan switch dan router sudah saling terkoneksi ..?

Konfigurasi Pada Router Jupiter:

Router>enable
Router#configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#hostname Rjupiter
Rjupiter(config)#interface fa0/0
Rjupiter(config-if)#ip address 192.168.1.100 255.255.255.0
Rjupiter(config-if)#no shutdown

%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up
Rjupiter(config-if)#exit
Rjupiter(config)#interface serial0/0
Rjupiter(config-if)#ip address 172.16.1.100 255.255.0.0
Rjupiter(config-if)#no shutdown

%LINK-5-CHANGED: Interface Serial0/0, changed state to down
Rjupiter(config-if)#clock rate 128000
Rjupiter(config-if)#

Konfigurasi Pada Router Leo:

Router>enable
Router#configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#hostname Rleo
Rleo(config)#interface FastEthernet0/0
Rleo(config-if)#ip address 10.10.10.100 255.0.0.0
Rleo(config-if)#no shutdown

%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up
Rleo(config-if)#exit
Rleo(config)#interface serial0/0
Rleo(config-if)#ip address 172.16.1.200 255.255.0.0
Rleo(config-if)#no shutdown

%LINK-5-CHANGED: Interface Serial0/0, changed state to up
Rleo(config-if)#
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/0, changed state to up
Rleo(config-if)#clock rate 128000
Rleo(config-if)#

Lakukan koneksi ping dari router ke computer

Proses routing para router1

Router 1 jika ingin menjangkau network 10.0.0.0 harus melalui IP address 172.16.1.200 sehingga IP ini dapat menjadi  gateway bagi router, konfigurasi nya adalah sebagai berikut :

Rjupiter#config t

Enter configuration commands, one per line.  End with CNTL/Z.

Rjupiter(config)#ip route 10.0.0.0 255.0.0.0 172.16.1.200

Rjupiter(config)#exit

%SYS-5-CONFIG_I: Configured from console by console

Rjupiter#show ip route

Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP

       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2

       E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP

       i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area

       * - candidate default, U - per-user static route, o - ODR

       P - periodic downloaded static route

Gateway of last resort is not set

S    10.0.0.0/8 [1/0] via 172.16.1.200

C    172.16.0.0/16 is directly connected, Serial0/0

C    192.168.1.0/24 is directly connected, FastEthernet0/0
