mengenai dasar redistribution. Secara default, router hanya meng-advertise dan berbagi route dengan router lain yang menjalankan protokol yang sama. Nah, misal jika kita memiliki banyak router yang mana tiap router mempunyai tipe routing yang berbeda misal Sakti-R1 menggunakan OSPF dan Sakti-R2 menggunakan EIGRP, dan kita ingin agar tiap routing tersebut dapat terhubung, mengetahui route satu sama lain dan juga dapat saling bertukar data, maka kita gunakan fitur redistribution ini. Dengan kita gunakan konfigurasi reditribuion ini berarti tiap tipe routing akan mengambil route dari tipe routing lain dan mendistribusikannya ke protocol lain pula.



Redistribution berfungsi untuk mengubungkan tipe-tipe routing yang telah dibahas di part sebelumnya. Tipe routing yang dapat diredistribute dapat berupa static routing maupun dynamic routing.

Sakti-R7 dengan Sakti-R8 untuk tipe Static routing. Konfigurasikan static default di Sakti-R7 dan di Sakti-R8 konfigurasikan static routing dan static defult route. Di Sakti-R7 dikonfigurasikan hanya static default route dikarenakan Sakti-R7 sudah directly connected network.

Selanjutnya kita setting konfigurasi redistributions di Sakti-R9. Pertama,konfigurasikan routing tipe RIPv2 yang mengarah ke Sakti-R2. Masih dalam mode routing RIPV2, langsung redistribute tipe routing RIPv2 tersebut dengan tipe routing lain yang ada.

Sakti­R9(config)#router rip
Sakti­R9(config­router)#version 2
Sakti­R9(config­router)#network 101.101.101.0

Sakti­R9(config­router)#redistribute eigrp 10 metric 1
Sakti­R9(config­router)#redistribute static 
Sakti­R9(config­router)#exit
Sakti­R9(config)#

Kedua, konfigurasikan routing tipe OSPF yang mengarah ke Sakti-R3. Masih dalam mode
routing OSPF 1, langsung reditribute tipe OSPF tersebut dengan tipe routing lain.

Sakti­R9(config)#router ospf 1
Sakti­R9(config­router)#net 102.102.102.0 0.0.0.255 area 0
Sakti­R9(config­router)#redistribute rip subnets 
Sakti­R9(config­router)#redistribute eigrp 10 subnets 
Sakti­R9(config­router)#redistribute static subnets 
Sakti­R9(config­router)#exit
Sakti­R9(config)#

Ketiga, konfigurasikan routing tipe EIGRP yang mengarah ke Sakti-R6. Masih dalam mode routing EIGRP, langsung reditribute tipe EIGRP tersebut dengan tipe routing lain.

Sakti­R9(config)#router eigrp 10
Sakti­R9(config­router)#network 103.103.103.0
Sakti­R9(config­router)#no auto­summary 
Sakti­R9(config­router)#redistribute rip metric 1 1 1 1 1
