Judul dari tulisan ini adalah redistribute routing, berarti pertukaran 2 routing protokol atau lebih yang memiliki perbedaan baik dari sisi metric, administrative distance, classful, classless dan karakter pengiriman paket data. Berikut ini kutipan yang saya ambil dari cisco tentang redistribution routing protocol.
The use of a routing protocol to advertise routes that are learned by some other means, such as by another routing protocol, static routes, or directly connected routes, is called redistribution. While running a single routing protocol throughout your entire IP internetwork is desirable, multi-protocol routing is common for a number of reasons, such as company mergers, multiple departments managed by multiple network administrators, and multi-vendor environments. Running different routing protocols is often part of a network design. In any case, having a multiple protocol environment makes redistribution a necessity.
Differences in routing protocol characteristics, such as metrics, administrative distance, classful and classless capabilities can effect redistribution. Consideration must be given to these differences for redistribution to succeed.
Redistribution RIP-OSPF

Basic Knowledge
Pada router mana harus dipertukarkan 2 routing yang berbeda.
– Jawab : Pertemuan 2 routing protokol terjadi pada Router r3, maka konfigurasi pertukaran akan diletakkan di Router r3.
Konfigurasi policy yang harus dituliskan agar masing-masing routing protocol dapat menerima network yang diakomodir oleh routing protokol lawan.
*Pada cisco tidak mengunakan policy sehingga tabel routing otomatis dishare, karena aturan “Default Export& Import Policy” yang diterapkan oleh junos menyebabkan suatu tbel routing protokol tertentu tidak dapat secara default dishare*.
Default export policy RIP adalah “Reject everything. To export RIP routes, you must configure an export policy for RIP”. Jadi kita harus mengkonfigurasi export policy untuk menerima tabel routing baik dari RIP maupun OSPF. Untuk melihat Default Export & Import Policy, klik link disamping ini : Default Export & Import Policy.

Barly Wicaksono 
Bos Barly,
saya Bambang EP Alumni UII Juga 2004
saya mau tanya neh karena saya belum begitu paham juniper, Mohon pencerahan nya
Jadi Firewal Juniper saya IP nya 192.168.60.1 /24 ( segment kita 192.168.1.0/24)
Dibawah Firewall ada Cisco 3560X Masih LAN Base,
Sekarang ini kami ada router WAN dimana IP Lan nya 192.168.60.240
dimana connect ke Japan, dan terconnect ke switch 3560
Pertanyaan nya
dari Japan sudah bisa connect ke jaringan kami 192.168.60.0/24
Tapi dari local kami tidak bisa ping ke mereka. hanya bisa dari swith ping ke mereka, IP Japan 192.168.1.1 192.168.1.5 dsb( 192.168.1.0)
Kalo IP PC saya saya rubah gateway ke 192.168.60.240 saya baru bisa connect ke Japan,
Saya sudah coba add static rute di Juniper
route : 192.168.1.0 /24 Next Hop 192.168.60.240
Kok masih tidak bisa yah.
Mohon advice nya
salam Alumni

sorry salah ketik.. Network segment kami 192.168.60.0 /24
Yang di Japan 192.168.1.0

1. Di firewall itu harus dikonfigurasi zone-nya.
2. Di switch 3560 itu harus dikonfigurasi statik route kearah router Firewall.

lah itu masalahnya mas…3560 ga bisa routing,,, karena masih LAN BASE.. 😦

LAN Base bukannya bisa statik route ya basicnya?
