Summarization Route via CLI dan Config

Pengenalan Summarization adalah penyederhanaan ip route static  agar pencarian mudah dan effisien,


Alamat IP yang di summarization
Subnet Mask
Nilai 14 bit yang sama
Nilai Bit yang berbeda
 dianggap 0
172.16.0.0/16
10101100.00010000.00000000.00000000
172.17.0.0/16
10101100.00010001.00000000.00000000
172.18.0.0/16
10101100.00010011.00000000.00000000
Subnet mask yang berbeda (warna Hijau) anggap sebagai 0 jadi hasil yang didapat dari summarization jadi 10101100.000010000.00000000.00000000 atau 255.252.0.0

lebih jelas nya kita lihat topologi dibawah ini 
pertama kita akan mengconfig melalui CLI 
R1
Router>enable
Router#configure terminal

Router(config)#interface fastEthernet 0/0
Router(config-if)#no sh
Router(config-if)#ip address 172.18.0.1 255.255.0.0

Router(config-if)#ex

Router(config)#interface fastEthernet 1/0
Router(config-if)#no sh
Router(config-if)#ip address 172.19.0.1 255.255.0.0

Router(config-if)# ex

Router(config)#interface Serial2/0
Router(config-if)#no shutdown
Router(config-if)#clock rate 64000
Router(config-if)#ip address 172.17.0.1 255.255.0.0
R2
Router>enable
Router#configure terminal

Router(config)#interface FastEthernet0/0
Router(config-if)#ip address 172.16.0.1 255.255.0.0
Router(config-if)# no sh

Router(config-if)# ex

Router(config)#interface Serial2/0
Router(config-if)#no shutdown
Router(config-if)#clock rate 64000
Router(config-if)#ip address 172.17.0.2 255.255.0.0

Router(config-if)# ex

Router(config)#interface Serial3/0
Router(config-if)#no shutdown
Router(config-if)#clock rate 64000
Router(config-if)#ip address 172.15.0.1 255.255.0.0

R3

Router>enable
Router#configure terminal

Router(config)#interface FastEthernet0/0
Router(config-if)#ip address 10.0.0.1 255.255.0.0
Router(config-if)# no sh


Router(config-if)# ex

Router(config)#interface Serial3/0
Router(config-if)#no shutdown
Router(config-if)#clock rate 64000
Router(config-if)#ip address 172.15.0.2 255.255.0.0



Selanjutnya kita lakukan IP route pada masing masing Router

R1

Router>enable
Router#configure terminal
Router(config)#ip route 172.16.0.0 255.252.0.0 172.17.0.2 (Summarization)
Router(config)#no ip route 10.0.0.0 255.255.0.0 172.17.0.2

R2

Router>enable
Router#configure terminal
Router(config)#ip route 172.16.0.0 255.252.0.0 172.17.0.1 (Summarization)
Router(config)#ip route 10.0.0.0 255.255.0.0 172.15.0.2
R3

Router>enable
Router#configure terminal
Router(config)#ip route 172.16.0.0 255.252.0.0 172.15.0.1 (Summarization)
