Instalasi Step by Step Routing Daemon Quagga pada Centos 5.2
Router adalah peralatan atau device yang melakukan fungsi routing, Routing adalah proses meneruskan paket data dari satu network menuju network lain, sehingga data mempunyai path dalam mencapai suatu destination atau tujuan, routing bisa terjadi karena adanya routing tabel, routing tabel bisa terbentuk dengan dua cara yaitu secara Static dan Dyamic. Quagga adalah Routing Daemon yang mendukung routing protokol static maupun routing protocol dynamic seperti RIP, OSPF maupun routing antar Autonomus System yaitu BGP. Dengan Quagga kita bisa menjadikan suatu PC menjadi router yang murah dan cukup handal. Pada tulisan kali ini akan dijelaskan proses step by step instalasi routing daemon Quagga pada Centos 5.2
PERSYARATAN SEBELUM INSTALASI QUAGGA PADA CENTOS 5.2
- Download iso CentOS 5.2 DVD atau CD atau versi yang terbaru pada mirror yang terdekat atau pada ftp://ftp.unsri.ac.id/linux/Centos/. Lakukan burning ke DVD atau CD
- Mempunyai koneksi internet
- IP address yang dipergunakan pada tutorial ini yaitu IP address 192.168.1.4/24 untuk eth0 dan IP address 192.168.2.1/24 untuk eth1
INSTALASI CENTOS
Masukkan DVD atau CD1 dari Centos, dan atur BIOS supaya melakukan booting dari DVD/CD
Lakukan Skip untuk menghemat waktu
Klik Next
Untuk pemilihan language pilih English, kecuali anda mengerti bahasa yang lain
Pilih keyboard dengan layout U.S. English
Klik Yes
Pilih Review and modify partitioning layout
Tidak pilihan lain (no where to run :-p ) klik yes
Pilih Reset dan klik yes
Klik New, Mount Point pilih /boot ketik size 100 dan klik Ok
Klik bagian partisi yang masih free, klik New, pada File System Type pilih Swap, dan masukkan nilai sebaiknya sebesar dua kali ukuran RAM pada komputer kita, misal ukuran RAM kita 512 maka masukkan nilai 1024, atau anda boleh memasukkan nilai lebih besar dari ukuran tersebut.
Klik Free partisi lagi, klik New, Mount Point / (root), pilih Fill to maximum allowable size, sehingga sisa seluruh partisi kan dijadikan partisi root, klik Ok
Klik Next
Klik Next
Untuk Network Device, klik Active on Boot, dan untuk pemberian IP address biarkan dahulu secara automatically via DHCP, sebab nanti kita akan melakukan setting IP address secara manual
Pilih Asia/Jakarta
Masukkan password root, sesuai dengan password yang anda kehendaki
Pilih server, Customize now, klik Next
Untuk pemilihan paket
- Pada Desktop Environment jangan melakukan pemilihan packet
- Applications pilihlah Editors, Text Based Internet
- Pada Developments, pilihlah Development Libraries, Development Tools
- Pada Servers pilihlah, DNS Name Servers, Network Server, Server Configuration Tools, klik Network Server dan pilihlah DHCP dan Quagga
- Untuk Base system, pilihlah Administration Tools, Base, System Tools
- Dan kosongkan untuk pilihan paket yang lain
Klik Next
Hardisk sedang di format
Proses Instalasi tengah berlangsung
Klik Reboot, proses instalasi selesai
DISABLE DAN FIREWALL AND SELINUX
Pilih Firewall configuration dan klik Run Tool
Pada Security Level dan SELinux pilih Disabled, klik OK
Pilih Exit dan Enter
Setelah masuk ke console masukkan username dan password anda, langkah berikutnya kita akan melakukan import GPG keys untuk paket software yang sudah kita instalasi
[root@localhost ~]# rpm –import /etc/pki/rpm-gpg/RPM-GPG-KEY*
Agar kita dapat menginstal maupun mengupdate paket yang tidak terdapat pada repository Centos 5.2 lakukan import GPG keys dari wieers.com
[root@localhost ~]# rpm –import http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt
SETTING IP ADDRESS PADA INTERFACE ROUTER
[root@localhost network-scripts]# vi ifcfg-eth0
NAME=”"
GATEWAY=192.168.1.1
BOOTPROTO=static
HWADDR=00:0C:29:89:CF:E6
DEVICE=eth0
MTU=”1500″
NETMASK=”255.255.255.0″
BROADCAST=”192.168.1.255″
IPADDR=”192.168.1.4″
NETWORK=”192.168.1.0″
ONBOOT=yes
[root@localhost network-scripts]# vi ifcfg-eth1
NAME=”"
BOOTPROTO=static
HWADDR=00:0C:29:89:CF:F0
DEVICE=eth1
MTU=”1500″
NETMASK=”255.255.255.0″
BROADCAST=”192.168.2.255″
IPADDR=”192.168.2.1″
NETWORK=”192.168.2.0″
ONBOOT=yes
[root@localhost network-scripts]# service network restart
INSTALL DAN UPDATE MENGGUNAKAN YUM
Perintah Yum (Yellow dog Updater Modified) dapat kita gunakan untuk menginstal maupun mengupdate paket secara online dan otomatis akan mencari paket yang kita inginkan tersebut menuju site yang mempunyai repository Centos
INSTALASI QUAGGA
Perintah ini akan menginstalasi quagga jika kita lupa memilih paket Quagga pada saat proses instalasi, dan akan mendownload versi terbaru dari Quagga termasuk file-file dependencies-nya.
[root@localhost ~]# yum install quagga
Masuk ke direktori /etc/quagga/
[root@quagga ~]# cd /etc/quagga/
Melihat daftar file pada direktori tersebut
[root@quagga quagga]# ls
bgpd.conf.sample ospfd.conf.sample vtysh.conf zebra.conf.sample
bgpd.conf.sample2 ripd.conf.sample vtysh.conf.sample
ospf6d.conf.sample ripngd.conf.sample zebra.conf
Terlihat disitu terdapat file zebra.conf.sample yang merupakan file sample konfigurasi awal dari Quagga, dikarenakan file zebra.conf masih belum ada konfigurasinya ada baiknya kita me-rename atau meng-copy file tersebut dengan nama lain, disini kita akan mengubah nama zebra.conf menjadi zebra.conf.backup, gunakanlah perintah mv
[root@quagga quagga]# mv zebra.conf zebra.conf.backup
Copy zebra.conf.sample menjadi zebra.conf
[root@quagga quagga]# cp zebra.conf.sample zebra.conf
Pada contoh instalasi ini kita akan menggunakan routing protocol OSPF, karena itu ubah nama ospfd.conf.sample menjadi ospfd.conf, jika anda ingin menggunakan protocol yang lain seperti RIP dan BGP maka anda bisa melakukan hal yang sama.
[root@quagga quagga]# cp ospfd.conf.sample ospfd.conf
Lakukan perintah start pada Quagga dan OSPF, agar keduanya diaktifkan dan dijalankan
[root@quagga quagga]# service zebra start
[root@quagga quagga]# service ospfd start
Atur kedua aplikasi juga diaktifkan pada saat boot
[root@quagga quagga]# chkconfig zebra on
[root@quagga quagga]# chkconfig ospfd on
Quagga maupun routing protocol yang digunakan mempunyai file konfigurasi yang berbeda, jika kita terbiasa menggunakan router Cisco maupun Vyatta, kita tidak perlu melakukan konfigurasi secara terpisah, jadi antara Quagga dan routing protocol-nya pun mempunyai service tersendiri, memang agak sedikit ruwet tetapi bagi kita yang menyukai proses ketimbang semata-mata hasil, tentu hal ini merupakan suatu keasyikan tersendiri. Untuk melihat daftar port yang digunakan masing-masing service tersebut, kita bisa melihatnya dengan perintah vi /etc/services
[root@quagga quagga]# vi /etc/services
————————————————cut——————————————————–
# Ports numbered 2600 through 2606 are used by the zebra package without
# being registred. The primary names are the registered names, and the
# unregistered names used by zebra are listed as aliases.
hpstgmgr 2600/tcp zebrasrv # HPSTGMGR
hpstgmgr 2600/udp # HPSTGMGR
discp-client 2601/tcp zebra # discp client
discp-client 2601/udp # discp client
discp-server 2602/tcp ripd # discp server
discp-server 2602/udp # discp server
servicemeter 2603/tcp ripngd # Service Meter
servicemeter 2603/udp # Service Meter
nsc-ccs 2604/tcp ospfd # NSC CCS
————————————————cut——————————————————–
Terlihat disitu bahwa Quagga menggunakan port 2601 dan OSPF menggunakan port 2604, lakukan telnet untuk mengakses service tersebut dengan menggunakan IP loopback 127.o.o.1 dan port yang dipergunakan oleh masing-masing service, sehingga kita bisa melakukan konfigurasi. Bagi yang terbiasa melakukan konfigurasi pada router Cisco, tentu melakukan konfigurasi pada Quagga bukanlah kesulitan yang berarti sebab perintah yang dipergunakan mempunyai banyak kemiripan walau saya sendiri tidak bisa mengatakan berapa persen tingkat kesamaan perintah antara Quagga dan Cisco, silahkan anda cari di Google.
Disini kita akan coba memberikan IP address pada masing-masing interface, sebagai contoh untuk eth0 kita akan menggunakan IP address 192.168.1.4/24 dan untuk eth1 IP address 192.168.2.1/24, dan password yang pertama kali digunakan untuk login adalah zebra

Pada Privilige Mode ada baiknya kita memeriksa terlebih dahulu interface apa saja yang terdapat pada router kita, hal ini sangat membantu kita pada saat akan melakukan konfigurasi pada interface seperti pemberian IP Address maupun konfigurasi yang lain, lakukan dengan perintah show interface
Router# show interface
Setelah mengetahui interface yang terdapat router kita, masuk ke Global Configuration Mode, ketikkan perintah configure terminal atau anda bisa menyingkat dengan perintah config t
Router# configure terminal
Masuk ke Interface Mode, untuk memberikan IP address pada interface eth0 kita bisa masuk dengan perintah interface eth0
Router(config)# interface eth0
Memberikan IP address
Router(config-if)# ip address 192.168.1.4/24
Router(config-if)# no shutdown
Router(config-if)# exit
Masuk ke interface eth1 dan lakukan hal yang sama seperti pada eth0
Router(config)# interface eth1
Router(config-if)# ip address 192.168.2.1/24
Router(config-if)# no shutdown
Router(config-if)# exit
Dikarenakan kita akan menggunakan OSPF sebaiknya kita juga memberikan IP Address pada interface loopback yang berfungsi sebagai router-ID. Untuk mengerti interface loopback dan router-ID baca tulisan terlebih dahulu mengenai setting router dengan OSPF dan Vyatta pada jaringan inherent
Router(config)# interface lo
Router(config-if)# ip address 10.0.0.1/32
Router(config-if)# exit
Ubah nama hostname
Router(config)# hostname quagga-unsri
Ubah enable password, dimana password ini akan dipergunakan sebagai password untuk masuk ke privilege mode
quagga-unsri(config)# enable password kayarayaselamanya
Ubah password untuk telnet, yang berfungsi sebagai password pada saat kita mengakses Quagga melalui telnet
quagga-unsri(config)# password matimasuksurga
quagga-unsri(config)# exit
Melihat dan mem-verifikasi konfigurasi yang sudah dibuat, apakah sudah sesuai dengan konfigurasi yang kita inginkan lakukan dengan perintah show running-config
quagga-unsri# show running-config
Current configuration:
!
hostname quagga-unsri
password matimasuksurga
enable password kayarayaselamanya
!
interface eth0
ip address 192.168.1.4/24
ipv6 nd suppress-ra

Untuk menyimpan hasil konfigurasi lakukan dengan perintah copy running-config startup-config
quagga-unsri# copy running-config startup-config
Maka konfigurasi akan disimpan pada file zebra.conf
Configuration saved to /etc/quagga/zebra.conf
Keluar dari Quagga

Sampai disini tutorial step by step mulai dari instalasi Centos 5.2 dan konfigurasi sederhana pada Quagga telah kita lakukan, router kita telah siap untuk menerima tugas selanjutnya, pada tulisan berikutnya kita akan coba untuk melakukan routing dengan beberapa router dengan OS yang berbeda dan dengan skenario yang lebih komplek , kita akan melihat bagaimana mereka melakukan tugasnya sebagai router dalam meneruskan paket dari suatu network menuju network lain.
Sebaik-baiknya manusia adalah manusia yang berguna bagi orang lain, mari saling berbagi dan menulislah, sebab ilmu laksana binatang liar, jinakkan mereka dengan cara menulis.

Routing protocol OSPF dengan Vyatta untuk sub local node INHERENT ke local node UNSRI
Routing, adalah sebuah proses untuk mem-forward paket data dari satu network menuju network lain. Dengan Routing kita dapat membuat dua atau lebih network yang berbeda saling berkomunikasi. Untuk melakukan hal ini, diperlukan suatu peralatan yang disebut router. Pada saat router menerima suatu packet data maka router akan membaca alamat yang menjadi tujuan berdasarkan header yang terdapat pada packet, setelah router mengetahui kemana alamat yang akan dituju maka router akan melihat routing table Dengan routing table inilah maka router akan tahu kemana ia akan meneruskan packet data tersebut.
Routing table menyimpan informasi mengenai network yang terhubung dengannya (Connected Networks) maupun netwok yang tidak terhubung dengannya (Remote networks). Connected networks adalah network yang terhubung dengan salah satu interface pada router. Remote networks adalah network yang tidak terhubung langsung dengan salah interface pada router. Routing Table bisa dibentuk dengan berbagai macam cara yaitu dengan Static Routing maupun Dynamic Routing.
Static Routing adalah Routing Table yang dibentuk dengan cara di-entry secara manual oleh network administrator, sedangkan Dynamic Routing adalah Routing Table yang dibentuk secara otomatis dengan menggunakan dynamic routing protocols.
Dynamic Routing Protocol dibagi kedalam dua kategori yaitu IGP (Interior Gateway Protocols) Â dan EGP (Exterior Gateway Protocol)
Interior Gateway Protocols (IGPs) adalah protocol yang melakukan routing didalam satu autonomous systems sedangkan Exterior Gateway Protocol (EGPs) adalah protocol yang melakukan routing antar autonomous systems
IGPs dibagi ke dalam dua kategori lagi yaitu
- distance-vector
- link-state protocols
Distance-vector protocol antara lain:
- Routing Information Protocol (RIP)
- Interior Gateway Routing Protocol (IGRP)
- Enhanced IGRP (EIGRP)
Link-state protocols antara lain
- Open Shortest Path First (OSPF)
- Intermediate System-to-Intermediate System (IS-IS).
EGPs
Border Gateway Protocol (BGP).
Inherent (Indonesia Higher Education Network) memilih menggunakan protocol OSPF dikarenakan selain OSPF merupakan protocol open system yang bisa digunakan pada router buatan suatu vendor tertentu maupun router yang dibangun dengan software open source, selain itu dikarenakan OSPF menggunakan Link State Algortitma yaitu jika suatu router yang dikonfigurasi dengan link-state routing protocol maka router tersebut akan membuat suatu “complete view” dari sebuah topologi dengan cara mengumpulkan informasi dari seluruh router. Sehingga mempunyai “the best path” atau jalan terbaik keseluruh network tujuan dalam suatu topologi.
Dalam membuat suatu complete view suatu router harus mencapai kondisi convergence yaitu kondisi dimana seluruh routing table berada dalam kondisi “state of consistency”. Suatu network disebut sudah convergence jika seluruh router sudah mempunyai routing table yang lengkap dan akurat terhadap network. Sedangkan untuk mencapai kondisi convergence, suatu router membutuhkan convergence time yaitu waktu yang dibutuhkan router untuk berbagi infomasi, melakukan kalkulasi “the best paths“, dan melakukan update terhadap routing tables. Secara Umum, RIP and IGRP mempunyai time converge yang lambat, sedangkan EIGRP and OSPF mempunyai time converge yang lebih cepat.
OSPF dikonfigurasi dengan menggunakan perintah router ospf process-id. Process-id adalah nilai antara 1 and 65535 yang dipilih oleh network administrator. Nilai Process-id bersifat local maksudnya tidak mempengaruhi OSPF routers untuk membangun hubungan dengan router yang bersebelahan. Di dalam topologi inherent, pengelola menggunakan area-id untuk dijadikan process-id
R1(config)#router ospf <process-id>
Router(config-router)#network network-address wildcard-mask area area-id
OSPF network menggunakan gabungan network-address, wildcard-mask dan area-id
Contoh:
R1’s FastEthernet 0/0 interface mempunyai alamat nerwork 167.205.182.124/30. Subnet mask untuk interface ini /30 atau 255.255.255.252. Untuk mendapatkan subnet masknya kurangkan nilai 255.255.255.255 dengan 255.255.255.252, hasil dari pengurangan tersebut menghasilkan wildcard mask
255.255.255.255
- 255.255.255.252 Subtract the subnet mask
——————-
0. 0. 0. 15 Wildcard mask
Area-id merujuk ke OSPF area. OSPF area kumpulan dari routers yang saling berbagi informasi link-state. Seluruh routers pada area yang sama harus mempunyai informasi link-state yang sama pada link-state databases-nya.
OSPF router ID digunakan sebagai identitas unik tiap router pada OSPF. Router ID secara simpel ada sebuah IP address. Routers menentukan ID didasarkan 3 kriteria yaitu:
- Menggunakan IP address yang dikonfigurasi dengan perintah OSPF router-id
- Jika router-id tidak dikonfigurasi, maka router akan memilih IP address tertinggi pada interface loopback.
- Jika interfaces loopback tidak ada yang dikonfigurasi maka router akan memilih IP address tertinggi dari interface fisik.
Adapun Interface Loopback adalah Interface yang bersifat logic atau virtual, interface ini tidak ada dalam bentuk fisik, dan sama halnya dengan interface fisik, interface ini mendapat perlakuan yang sama dengan interface fisik, antara lain mendapat alamat IP dan Subnet Mask seperti halnya kita memberikan IP pada Interface fisik, dan karena bersifat logic tentu interface ini tidak akan mengalami kondisi down seperti Interface fisik, sehingga ia merupakan suatu interface yang aktif setiap saat, dan kalau interface ini di-set dengan diberikan IP maka routing protokol OSPF akan menjadikan alamat IP pada interface loopback ini sebagai Router-ID untuk router tersebut. Dan ia bukan interface yang menghubungkan suatu network ke router, interface ini hanya membutuhkan satu alamat IP sehingga di konfigurasi dengan subnet mask bernilai 255.255.255.255 atau semua bit bernilai 1 atau dalam bentuk prefix yaitu /32
Router dengan Software Open Source Vyatta
(Konfigurasi oleh PT yang terhubung)
Download iso versi terbaru dari Vyatta pada http://vyatta.org (Thanks to Vyatta). Burning ke CD, kemudian booting PC yang akan dijadikan router dari CD ROM (vyatta sangat hemat resource, pengalaman menunjukkan dengan Pentium 4 RAM 256 dan Hardisk 40 GB, Vyatta menunjukkan performance yang cukup baik).

CONFIGURATION REGISTER
Cisco mempunyai software register 16 bit yang ditulis pada nonvolatile memory. Configuration register diatur secara default untuk me-load Cisco IOS dari flash dan me-load startup-config dari NVRAM
Kita bisa mengubah configuration register untuk keperluan:
- Memaksa system untuk masuk bootstrap monitor
- Memilih sebuah boot source dan default boot filename
- Enable atau men-disable fungsi break
- Mengontrol alamat broadcast
- Mengatur baud rate terminal console
- Me-load software operating dari ROM
- Booting dari TFTP server
Konfigurasi default pada Cisco router adalah 0×2102
Nomor bit pada configuration register
|
16 bit |
||||||||||||||||
| Configuration register | 2 | 1 | 0 | 2 | ||||||||||||
| Bit Number | 15 | 14 | 13 | 12 | 11 | 10 | 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
| Binary | 0 | 0 | 1 | 0 | 0 | 0 | 0 | 1 | 0 | 0 | 0 | 0 | 0 | 0 | 1 | 0 |
Prefix 0x pada alamat configuration register (0×2102) untuk menunjukkan bilangan yang digunakan adalah hexadecimal
Maksud dari Nomor Bit
| Bit No. | Hexadecimal | Deskripsi |
| 0-3 | 0×0000-0×000F | Boot field lihat tabel bootfield |
| 6 | 0×0040 | Abaikan isi NVRAM |
| 7 | 0×0080 | OEM bit enabled |
| 8 | 0×0100 | Break disabled |
| 10 | 0×0400 | IP Broadcast with all zero |
| 11-12 | 0×0800-0×1000 | Kecepatan line console |
| 13 | 0×2000 | Boot default ROM software if network boot fails |
| 14 | 0×4000 | IP broadcast do not have net number |
| 15 | 0×8000 | Enable diagnostic messages and ignore NVRAM contents |
Bit ke 6 digunakan untuk mengabaikan isi dari NVRAM
Boot field
| Boot field | Meaning |
| 00 | ROM Monitor Mode |
| 01 | Boot image from ROM |
| 02-F | Specifies a default netboot filename |
Untuk boot ke mode ROM Monitor atur configuration register ke 0×2100, kemudian reboot router. Pada router akan muncul rommon>
Untuk booting ke mini-IOS images pada ROM (dikenal sebagai RXBOOT), atur configuration register ke 0×2101. Maka akan tampil router(boot)> Jika ini jenis router lama, atau akan muncul rommon 1> jika router berbasiskan RISC terbaru dengan sebuah “smart ROM” pengganti dari mini IOS.
Nilai dari 0×2102 sampai 0×210F untuk memberi tahu pada router untuk menggunakan perintah boot yang spesifik di NVRAM. Semua nilai dalam bentuk hexadecimal, skemanya adalah 0-9 dan A-F. (A=10, B=11, C=12, D=13, E=14, dan F=15). Sehingga kita mengatur configuration register sampai 210(15), atau 1111 dalam bentuk binary.
MENGUBAH CONFIGURATION REGISTER
Sebelum mengubah configuration register, maka perlu mengetahui nilai configuration register yang sudah ada. Pada router ketikkan perintah:
Router>enable

PASSWORD RECOVERY
Bit ke 6 pada configuration register merupakan bit yang digunakan untuk memberi tahu router apakah harus menggunakan isi dari NVRAM, atau malah sebaliknya untuk mengabaikan isi dari NVRAM.
Nilai default dari configuration register adalah 0×2102, dimana bit ke tersebut dinyatakan off, jika nilai ini off maka router akan mencari dan me-loading konfigurasi yang disimpan pada NVRAM (startup-config). Untuk melakukan recovery password, kita perlu memberi nilai pada bit ke 6 tersebut, sehingga router akan mengabaikan startup-config yang terdapat pada NVRAM, sedangkan konfigurasi mengenai password tersendiri disimpan pada startup-config tersebut, jika startup-config diabaikan maka router tidak akan membaca password yang sudah ada.
Untuk melakukan recovery password pada router, hubungkan router pada program hyperterminal. Setelah itu matikanlah router, kemudian pada keyboard computer tekan Control+break, dan nyalakan lagi router. Router akan masuk ke ROM monitor, pada ROM monitor ketik perintah confreg 0×2142
rommon 1 > confreg 0×2142
rommon 2 > reset
Setelah direset maka router akan masuk ke configuration dialog, ketik no
