2. Configurasi
semua router agar bisa saling terhubung menggunakan OSPF
Router 0
Router # sh ip route
172.16.0.0/24 is subnetted, 8 subnets
C 172.16.10.0 is directly
connected, FastEthernet0/0

Coba di cek dengan mengirim pesan dari salah satu
pc ke pc lain dengan router yang berbeda …………….pasti berhasil…………….jika tidak
……………berarti anda belum beruntung ,,,,,,,,,,salalulah berusaha jangan menyerah
pasti berhasil….

3.
Setting IP Address
LAN 10.1
Ip Address 172.16.10.5
Subnet mask 255.255.255.0
Defaul gateway 172.16.10.1
|
LAN 50.1
Ip Address 172.16.50.7
Subnet mask 255.255.255.0
Defaul gateway 172.16.50.1
|
LAN 20.1
Ip Address 172.16.20.163
Subnet mask 255.255.255.0
Defaul gateway 172.16.20.1
|
LAN 70.1
Ip Address 172.16.70.5
Subnet mask 255.255.255.0
Defaul gateway 172.16.70.1
|
LAN 40.1
Ip Address 172.16.40.89
Subnet mask 255.255.255.0
Defaul gateway 172.16.40.1
|

4. Terapkan ACL
ACL Standart di R1,karena ip 172.16.10.0 tidak di ijinkan untuk terhubung dengan
net 172.16.40.0
Router#conf t
Router (config)#access-list
10 deny 172.16.10.0 0.0.0.255
Router (config)#access-list
10 permit any
Router (config)#int
fa0/0
Router (config-if)#ip
access-group 10 out
Router (config-if)#
ACL Extended di R0, karena host 172.16.10.5 menolak untuk conecsi dengan
host 172.16.50.7
Router#conf t
Router (config)#access-list
115 deny ip host 172.16.10.5 host 172.16.50.7
Router (config)#access-list
115 permit ip any any
Router (config)#int
fa0/0
Router (config-if)#ip
access-group 115 in
Router (config-if)#
ACL Standart di R2
Router#conf t
Router (config)#access-list
20 permit host 172.16.10.5
Router (config)#line
vty 0 4
Router (config-line)#access-class
20 in
Router (config-line)#
Uji koneksi dengan ping
Ada masalah saat
melakukan pengujian ping :
- Pada PC yang IP address nya 172.16.40.89, tidak bisa terkoneksi dengan ip 172.16.10.0. tetapi dengan PC lain bisa terkoneksi.
- Pada PC yang ip address nya 172.16.10.5, bisa terkoneksi dengan PC yang lain tetapi jika melakukan pengujian dengan ip 172.16.50.7 yang terjadi adalah (RTO) dan dengan ip 172.16.40.89 malah (Destination host unreachable).
