konfigurasi ACLs pada router

sebelum mengkonfigurasikan ACLs pada router, saya akan mengingatkan bahwa dalam menghubungkan router pada ACLs ini  menggunakan router EIGRP.

selanjutnya konfigurasikan router seperti gambar di bawah ini dengan Soal ACLs :

• network 172.16.10.0 tidak bisa di akses oleh 172.16.40.0 dan yang lainnya bisa mengakses netwrk 10

• host 172.16.10.5 tidak bisa mengakses host 172.16.50.7

       1. Konfigurasi pada Router 1

Router>ena
Router#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#int fa0/0
Router(config-if)#ip add 172.16.10.1 255.255.255.0
Router(config-if)#no shut

Router(config-if)#
%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up

Router(config-if)#int fa1/0
Router(config-if)#ip add 172.16.20.1 255.255.255.0
Router(config-if)#no shut

%LINK-5-CHANGED: Interface FastEthernet1/0, changed state to up

Router(config-if)#int ser2/0
Router(config-if)#ip add 172.16.30.1 255.255.255.0
Router(config-if)#clock rate 64000
Router(config-if)#no shut

%LINK-5-CHANGED: Interface Serial2/0, changed state to down
Router(config-if)#exit
Router(config)#


       2. Konfigursi pada Router2

Router>ena
Router#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#int fa0/0
Router(config-if)#ip add 172.16.40.1 255.255.255.0
Router(config-if)#no shut

Router(config-if)#
%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up

Router(config-if)#int fa1/0
Router(config-if)#ip add 172.16.50.1 255.255.255.0
Router(config-if)#no shut

%LINK-5-CHANGED: Interface FastEthernet1/0, changed state to up

Router(config-if)#
Router(config-if)#int ser3/0
Router(config-if)#ip add 172.16.30.2 255.255.255.0
Router(config-if)#no shut

Router(config)#int ser2/0
Router(config-if)#ip add 172.16.60.1 255.255.255.0
Router(config-if)#no shut
Router(config-if)#clock rate 64000
Router(config-if)#

       3. Konfigurasi Pada Router 3

Router>ena
Router#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#int fa0/0
Router(config-if)#ip add 172.16.70.1 255.255.255.0
Router(config-if)#no shut

%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up

Router(config-if)#int fa1/0
Router(config-if)#ip add 172.16.80.1 255.255.255.0
Router(config-if)#no shut

%LINK-5-CHANGED: Interface FastEthernet1/0, changed state to up

Router(config-if)#int ser3/0
Router(config-if)#ip add 172.16.60.2 255.255.255.0
Router(config-if)#no shut

%LINK-5-CHANGED: Interface Serial3/0, changed state to down
Router(config-if)#

       4. Koneksikan Antar Router dengan EIGRP

• Pada Router1

          Router(config)#router eigrp 10
          Router(config-router)#net 172.16.10.0 0.0.0.255
          Router(config-router)#net 172.16.20.0 0.0.0.255
          Router(config-router)#net 172.16.30.0 0.0.0.255

• Pada Router2

          Router(config)#router eigrp 10
          Router(config-router)#net 172.16.40.0 0.0.0.255
          Router(config-router)#net 172.16.50.0 0.0.0.255
          Router(config-router)#net 172.16.60.0 0.0.0.255
          Router(config-router)#net 172.16.30.0 0.0.0.255

• Pada Router3

          Router(config)#router eigrp 10
          Router(config-router)#net 172.16.60.0 0.0.0.255
          Router(config-router)#net 172.16.70.0 0.0.0.255
          Router(config-router)#net 172.16.80.0 0.0.0.255

       5. Konfigurasi ACLs

• network 172.16.10.0 tidak bisa di akses oleh 172.16.40.0 dan yang lainnya bisa mengakses netwrk 10 (di setting Pada Router 1)

          Router(config)#access-list 3 deny 172.16.40.0 0.0.0.255
          Router(config)#access-list 3 permit any
          Router(config)#int fa0/0
          Router(config)#ip access-group 3 out

• host 172.16.10.5 tidak bisa mengakses host 172.16.50.7 (di setting Pada Router2)

           Router(config)#access-list 9 deny host 172.16.10.5
           Router(config)#access-list 9 permit any 
           Router(config)#ip access-group 3 out
