OSPF || Dewi Aisyah Blog
Assalamualaikum wr wb Haii :)
Kali ini saya akan melanjutkan konfigurasi LAB di Cisco Packet Tracert Selanjutnya Yaitu Lab OSPF
Kali ini saya akan melanjutkan konfigurasi LAB di Cisco Packet Tracert Selanjutnya Yaitu Lab OSPF
Tujuan
Setting OSPF
Setting router-id OSPF
Setting passive-interface dan network type loopback OSPF
Konsep Dasar
OSPF singkatan dari Open Shortest Path First
OSPF merupakan routing protocol open standar yang diimplementasikan oleh berbagai
macam vendor, termasuk Cisco
Link-state protocol
OSPF bekerja dengan menggunakan algoritma Dijkstra
Hop count unlimited
Metric: cost (cost=10^8 / BW)
Administrative Distance: 110
Classless routing protocol
Mendukung VLSM dan CIDR
Hanya mendukung equal cost load balancing
Terdapat konsep area untuk memudahkan manajemen dan control traffic
Menyediakan design hierarki dengan multiple area
Harus memiliki satu area yang disebut sebagai area 0 atau backbone area
Semua area selain 0 (non-backbone area) harus terhubung ke area 0
Dari scalabilitas lebih baik dibandingkan dengan protocol distance vector
Mendukung autentikasi
Update melalui multicast address: 224.0.0.5
Konvergensi cepat
Mengirimkan hello packet setiap 10 second
Trigger/Incrementeal updates
o Router mengirimkan update hanya jika terjadi perubahan dan tidak mengirimkan
semua routing table pada periodic update
OSPF memaintain tiga tabel
1. Neighbor table
- Dikenal juga sebagai adjacency database
- Menampilkan informasi directly connected router (neighbors)
- Command: show ip ospf neighbor
2. Database table
- Disebut juga sebagai LSDB (link state database)
- Menampilkan semua kemungkinan informasi route menuju network dalam satu area
- Command: show ip ospf database
3. Routing table
- Menampilkan best route menuju network destination
- Command: show ip route
Dua step menggunakan routing protocol dinamis secara umum:
1. Pilih routing protocol
2. Advertise directly connected network (jaringan yang terhubung langsung dengan router)
Konfigurasi OSPF
Router(config)# router ospf <process-id>
Router(config-router)# network <network-id> <wildcard-mask> area <area-id>
Router(config-router)# network <network-id> <wildcard-mask> area <area-id>
network <Network-ID> : untuk advertise network yang terhubung langsung dengan router
(directly connected network).
wildcard-mask
wildcard-mask : inverse subnet-mask
Keuntungan OSPF
Open standard
Tidak ada batasan jumlah hop
Loop free
Konvergensi lebih cepat
Kerugian OSPF
Mengkonsumsi lebih banyak resource CPU
Kompleks dalam hal design dan implementasi
Hanya mendukung equal load balancing
Hanya mendukung protocol IP
Konfigurasi
Login console ke R1 atau R2 untuk mempraktikkan Lab 8-OSPF.

Agar proses routing berhasil, harus disetting OSPF disemua router terlebih dulu. Setelah itu baru
diverifikasi dengan tes Ping end-to-end device-nya.

Setelah selesai setting OSPF di R2 step Halaman 53, di R1 maupun R2 akan muncul output
adjacent router OSPF. Dari output debug OSPF diatas R1 memiliki neighbor 172.16.4.4.
172.16.4.4 adalah router ID dari R2. Berarti R1 dan R2 telah menjalin relationship neighbor
(adjacency) sehingga routing update akan saling dikirimkan.
Setting router-id OSPF di R1
R1(config)#router ospf 1
R1(config-router)#router-id 111.111.111.111
R1(config-router)#Reload or use "clear ip ospf process" command, for this to

R2(config-router)#router-id 222.222.222.222
R2(config-router)#Reload or use "clear ip ospf process" command, for this to
take effect
R2(config-router)#
Setelah menjalankan command router-id diatas, jalankan command clear ip ospf
process untuk mereset proses OSPF di R1 maupun R2, sehingga router-id OSPF akan berubah.
R1#clear ip ospf process
Reset ALL OSPF processes? [no]: yes

Dari output neighbor table di R1, bisa kita lihat di kolom neighbor ID terdapat 222.222.222.222,
dimana 222.222.222.222 adalah router-id R2. Dengan demikian, setting router-id OSPF di R2 telah
berhasil.
Note: ulangi langkah yang sama diatas untuk mereset process OSPF dan tampilkan
neighbor table OSPF di R2, pastikan neighbor ID R1 111.111.111.111

Passive-interface OSPF memiliki kemiripan dengan EIGRP. Dengan mengaktifkan passiveinterface
di interface OSPF, maka akan menghentikan pengiriman paket hello sehingga akan
mencegah router membentuk relationship neighbor antar router, akibatnya router akan berhenti
melakukan update routing outgoing dan incoming (tidak dapat mengirimkan update routing dan
tidak dapat dikirimi update routing).
OSPF dan EIGRP sama-sama menggunakan paket hello sebelum membentuk relationship antar
router. Perhatikan informasi interface OSPF Fa0/0 dan Fa1/0 R1 diatas. Fa0/0 sudah diaktifkan
command passive-interface sehingga tidak ada lagi paket hello. Beda dengan Fa1/0 yang
ada keterangan Hello due in..
FastEthernet0/0 is up, line protocol is up
No Hellos (Passive interface)
FastEthernet1/0 is up, line protocol is up
Hello due in 00:00:07
Karena Network A dan Network B merupakan jaringan LAN dimana tidak membutuhkan
relationship neighbor antar router OSPF sehingga tidak jadi masalah ketika interface Fa0/0
diaktifkan command passive-interface-nya. Lain halnya dengan interface Fa1/0 ketika
diaktifkan command passive-interface, maka akan menimbulkan masalah yaitu R1 tidak
dapat membentuk relationship dengan R2, sehingga OSPF tidak dapat berjalan normal.
OSPF secara default memiliki hello interval = 10 second, dan dead interval = 40 second.
Interface Loopback di OSPF
Perhatikan sekali lagi output routing table di R1 dan R2. Apakah ada masalah dengan interface
loopback?

Semua loopback, yaitu Loopback1, Loopback2, Loopback3, Loopback4 menjadi stub host dengan network
type LOOPBACK. Stub host memang tampil di routing table dengan prefix /32, akan tetapi tidak dapat
digunakan untuk forwarding.
Agar semua loopback dapat di advertise oleh OSPF sebagai network dengan prefix aslinya yaitu /24, caranya
dengan mengubah network type loopback menjadi point-to-point.
Ubah Network Type Interface Loopback OSPF di R1 dan R2

EIGRP || Dewi Aisyah Blog
Assalamualaikum wr wb kali ini saya akan share Lab selanjutnya yaitu Lab EIGRP dan Konfigurasinya di P.t
Tujuan
Setting EIGRP
Debug EIGRP
Setting passive-interface EIGRP
Konsep Dasar
EIGRP disebut juga sebagai routing protocol distance vector, terkadang disebut juga advanced
distance vector atau routing protocol hybrid.
Berikut ini beberapa fitur dari EIGRP :
Cisco open standar protocol (sebelumnya proprietary)
Termasuk classless routing protocol
Update perubahan topologi secara dinamis
Metric (32 bit) : Composite Metric (BW + Delay + Load + MTU + Reliability)
Administrative Distance: 90
Update menggunakan multicast: 224.0.0.10
Jumlah maksimum hop count: 255 (default 100)
Mendukung protocol IP, IPX, Apple Talk
Hello packet dikirim setiap 5 second (dead interval 15 second)
Konvergensi cepat
Menggunakan algoritma DUAL (Diffusing Update Algorithm)
Mendukung equal dan unequal cost load balancing
EIGRP memaintain tiga tabel
1. Neighbor table
- Menampilkan informasi directly connected router
- Command: show ip eigrp neighbor
2. Topology table
- Menampilkan semua best route yang dipelajari dari masing-masing neighbor
- Command: show ip eigrp topology
3. Routing table
- Menampilkan best route menuju network destination
- Command: show ip route
Notes EIGRP
EIGRP menggunakan autonomous system number (ASN) untuk mengidentifikasi routerrouter
yang sharing informasi route
Hanya router yang memiliki ASN sama yang bisa sharing informasi route
Dua step menggunakan routing protocol dinamis secara umum:
1. Pilih routing protocol
2. Advertise directly connected network (jaringan yang terhubung langsung dengan router)
Konfigurasi EIGRP
Router(config)# router eigrp 100
Router(config-router)# network <Network ID>
Router(config-router)# network <Network ID> <Wildcard Mask>
Router(config-router)# no auto-summary
network <Network-ID> : untuk advertise network yang terhubung langsung dengan router
(directly connected network).
Keuntungan EIGRP
Terdapat backup route jika best route down (successor=primary, feasible
successor=backup)
Mendukung VLSM

Dari output diatas, hanya menampilkan directly connected network pada masing-masing router
yang ditandai dengan kode C. Untuk menghubungkan router agar bisa berkomunikasi dengan
network remote (yang tidak terhubung langsung dengan router) maka perlu disetting routing
protocol, salah satu contohnya yaitu EIGRP.

Berdasarkan output routing information di R1, kita bisa lihat bahwa R1 menggunakan EIGRP
dengan ASN 100 untuk network 12.0.0.0, 172.16.0.0, dan 192.168.1.0. EIGRP memiliki
Administrative Distance 120. Secara default hop-count EIGRP 100.

R1#
Terdapat 4 interface yang disetting EIGRP yaitu Fa1/0, Fa0/0, Lo1, Lo2.
Debug EIGRP R2
Pada saat kita mensetting EIGRP di R2 step sebelumnya pada Halaman 43, di R2 akan tampil
output seperti dibawah ini :
R2(config)#router eigrp 100
R2(config-router)#network 12.12.12.0
R2(config-router)#
%DUAL-5-NBRCHANGE: IP-EIGRP 100: Neighbor 12.12.12.1 (FastEthernet1/0) is up:

R2(config-router)#network 172.16.3.0
R2(config-router)#network 172.16.4.0
R2(config-router)#network 192.168.2.0
R2(config-router)#no auto-summary

%DUAL-5-NBRCHANGE: IP-EIGRP 100: Neighbor 12.12.12.1 (FastEthernet1/0) resync:

R2(config-router)#end
R2#
Setelah selesai setting EIGRP di R1, kemudian kita mensetting EIGRP di R2, setelah input network
12.12.12.0 di R2, muncul pesan neighbor adjacency yang ditambahkan ke dalam routing process
EIGRP. Oleh karena itu, saat kita verifikasi show ip eigrp neighbors R2 akan memiliki
neighbor 12.12.12.1 seperti tampilan dibawah ini :
R2#show ip eigrp neighbors
IP-EIGRP neighbors for process 100
H Address Interface Hold Uptime SRTT RTO Q Seq
(sec) (ms) Cnt Num
0 12.12.12.1 Fa1/0 10 00:23:38 40 1000 0 16
R2#
Selain itu juga terjadi proses resync saat kita mengetikkan command no auto-summary.
Untuk mengaktifkan debug paket EIGRP, gunakan command dibawah ini :
R2#debug eigrp packets
EIGRP Packets debugging is on
(UPDATE, REQUEST, QUERY, REPLY, HELLO, ACK )
EIGRP: Received HELLO on FastEthernet1/0 nbr 12.12.12.1

EIGRP: Received HELLO on FastEthernet1/0 nbr 12.12.12.1
AS 100, Flags 0x0, Seq 17/0 idbQ 0/0
Untuk menghentikan debug EIGRP packets, gunakan command berikut : no debug eigrp
packets
Setting passive-interface di R1
R1(config)#router eigrp 100
R1(config-router)#passive-interface fa0/0
R1(config-router)#
Dari output debug packet EIGRP, kita bisa lihat bahwa EIGRP menggunakan paket hello untuk
membentuk relationship dengan router tetangga (adjacent router). Apabila kita mengaktifkan
command passive-interface di interface maka akan menghentikan pengiriman paket hello
sehingga akan mencegah update routing outgoing dan incoming.
Karena Network A dan Network B tidak memerlukan paket hello, maka kita perlu mengaktifkan
passive-interface untuk interface di R1 dan R2 yang menuju Network A dan Network B.
Note: ulangi langkah yang sama diatas untuk setting passive-interface EIGRP di R2
Semoga Bermanfaat :-)

Terdapat 4 interface yang disetting EIGRP yaitu Fa1/0, Fa0/0, Lo1, Lo2.
Debug EIGRP R2
Pada saat kita mensetting EIGRP di R2 step sebelumnya pada Halaman 43, di R2 akan tampil
output seperti dibawah ini :
R2(config)#router eigrp 100
R2(config-router)#network 12.12.12.0
R2(config-router)#
%DUAL-5-NBRCHANGE: IP-EIGRP 100: Neighbor 12.12.12.1 (FastEthernet1/0) is up:

%DUAL-5-NBRCHANGE: IP-EIGRP 100: Neighbor 12.12.12.1 (FastEthernet1/0) resync:

R2(config-router)#end
R2#
Setelah selesai setting EIGRP di R1, kemudian kita mensetting EIGRP di R2, setelah input network
12.12.12.0 di R2, muncul pesan neighbor adjacency yang ditambahkan ke dalam routing process
EIGRP. Oleh karena itu, saat kita verifikasi show ip eigrp neighbors R2 akan memiliki
neighbor 12.12.12.1 seperti tampilan dibawah ini :
R2#show ip eigrp neighbors
IP-EIGRP neighbors for process 100
H Address Interface Hold Uptime SRTT RTO Q Seq
(sec) (ms) Cnt Num
0 12.12.12.1 Fa1/0 10 00:23:38 40 1000 0 16
R2#
Selain itu juga terjadi proses resync saat kita mengetikkan command no auto-summary.
Untuk mengaktifkan debug paket EIGRP, gunakan command dibawah ini :
R2#debug eigrp packets
EIGRP Packets debugging is on
(UPDATE, REQUEST, QUERY, REPLY, HELLO, ACK )
EIGRP: Received HELLO on FastEthernet1/0 nbr 12.12.12.1

EIGRP: Received HELLO on FastEthernet1/0 nbr 12.12.12.1
AS 100, Flags 0x0, Seq 17/0 idbQ 0/0
Untuk menghentikan debug EIGRP packets, gunakan command berikut : no debug eigrp
packets
Setting passive-interface di R1
R1(config)#router eigrp 100
R1(config-router)#passive-interface fa0/0
R1(config-router)#
Dari output debug packet EIGRP, kita bisa lihat bahwa EIGRP menggunakan paket hello untuk
membentuk relationship dengan router tetangga (adjacent router). Apabila kita mengaktifkan
command passive-interface di interface maka akan menghentikan pengiriman paket hello
sehingga akan mencegah update routing outgoing dan incoming.
Karena Network A dan Network B tidak memerlukan paket hello, maka kita perlu mengaktifkan
passive-interface untuk interface di R1 dan R2 yang menuju Network A dan Network B.
Note: ulangi langkah yang sama diatas untuk setting passive-interface EIGRP di R2
Semoga Bermanfaat :-)
RIPv2 || Dewi Aisyah Blog
Assalamualaikum wr wb kali ini saya akan share lab selanjutnya yaitu RIPv2
Tujuan
Setting RIPv2
Debug RIPv2
Setting passive-interface RIPv2
Konsep Dasar
Keuntungan menggunakan dynamic routing dibandingkan static routing:
Tidak perlu tahu network destination
Perlu melakukan advertise network yang terhubung langsung
Update perubahan topologi secara dinamis
Pekerjaan network admin jadi berkurang
Digunakan di industri besar
Neighbor router melakukan pertukaran informasi routing dan membangun routing table
secara otomatis
Lebih mudah dibandingkan menggunakan static routing
RIPv2
Open standar protocol (Cisco atau non-Cisco)
Classless routing protocol (support default atau sub-networks)
Mendukung VLSM
Mendukung Autentikasi
Menggunakan multicast address 224.0.0.9
Administrative distance: 120
Metric: hop count (terbaik = yang paling kecil)
Hop ke-16 unreachable
Load balancing 4 equal path
Digunakan untuk organisasi kecil
Update secara periodic dan pertukaran keseleruhan informasi routing tabel setiap 30
second
Dua langkah mudah setting routing protocol dinamis secara umum:
1. Pilih routing protocol
2. Advertise directly connected network (jaringan yang terhubung langsung dengan router)
Router(config)# router rip
Router(config-router)# version 2
Router(config-router)# network <Network ID>
Router(config-router)# no auto-summary
network <Network-ID> : untuk advertise network yang terhubung langsung dengan router
(directly connected network).
Keuntungan RIPv2
Mudah dikonfigurasi
Tidak memerlukan design seperti OSPF
Tidak kompleks
Less overhead
Kerugian RIPv2
Utilisasi bandwidth sangat tinggi karena diperlukan untuk broadcast setiap 30 second
(RIPv1)
Terbatas pada jumlah hop (bukan bandwidth)
Tidak scalable, hop count hanya 15
Konvergensi rendah
Waktu konvergensi: waktu yang dibutuhkan oleh router untuk menggunakan route alternative
ketika best route down.
Konfigurasi
Login console ke R1 atau R2 untuk mempraktikkan Lab 6-RIPv2.

Dari output debug RIP, kita bisa lihat bahwa RIP sudah running di router R1. Untuk menghentikan
output debug, gunakan command undebug ip rip atau undebug all.
Note: ulangi langkah yang sama diatas untuk menampilkan output debug RIP di R2
Setting passive-interface di R1
Untuk menghentikan routing updates yang dikirimkan ke Network A, maka aktifkan command
passive-interface di interface fa0/0 R1 yang menuju Network A. Hal ini tidak mempengaruhi
advertise Network A. Jadi, Network A masih tetap dikenali oleh R2 dan masih tampil di routing table
R2. Di routing protocol RIPv2, mengaktifkan passive-interface mencegah multicast update
melalui interface spesifik dan masih bisa mendapatkan update dari RIP neighbor yang lain.

Tujuan
Setting RIPv2
Debug RIPv2
Setting passive-interface RIPv2
Konsep Dasar
Keuntungan menggunakan dynamic routing dibandingkan static routing:
Tidak perlu tahu network destination
Perlu melakukan advertise network yang terhubung langsung
Update perubahan topologi secara dinamis
Pekerjaan network admin jadi berkurang
Digunakan di industri besar
Neighbor router melakukan pertukaran informasi routing dan membangun routing table
secara otomatis
Lebih mudah dibandingkan menggunakan static routing
RIPv2
Open standar protocol (Cisco atau non-Cisco)
Classless routing protocol (support default atau sub-networks)
Mendukung VLSM
Mendukung Autentikasi
Menggunakan multicast address 224.0.0.9
Administrative distance: 120
Metric: hop count (terbaik = yang paling kecil)
Hop ke-16 unreachable
Load balancing 4 equal path
Digunakan untuk organisasi kecil
Update secara periodic dan pertukaran keseleruhan informasi routing tabel setiap 30
second
Dua langkah mudah setting routing protocol dinamis secara umum:
1. Pilih routing protocol
2. Advertise directly connected network (jaringan yang terhubung langsung dengan router)
Router(config)# router rip
Router(config-router)# version 2
Router(config-router)# network <Network ID>
Router(config-router)# no auto-summary
network <Network-ID> : untuk advertise network yang terhubung langsung dengan router
(directly connected network).
Keuntungan RIPv2
Mudah dikonfigurasi
Tidak memerlukan design seperti OSPF
Tidak kompleks
Less overhead
Kerugian RIPv2
Utilisasi bandwidth sangat tinggi karena diperlukan untuk broadcast setiap 30 second
(RIPv1)
Terbatas pada jumlah hop (bukan bandwidth)
Tidak scalable, hop count hanya 15
Konvergensi rendah
Waktu konvergensi: waktu yang dibutuhkan oleh router untuk menggunakan route alternative
ketika best route down.
Konfigurasi
Login console ke R1 atau R2 untuk mempraktikkan Lab 6-RIPv2.

Static Default Route || Dewi Aisyah Blog
Assalamualaikum wr wb
Kali ini saya akan share Lab selanjutnya yaitu Lab Static Default Route
Kali ini saya akan share Lab selanjutnya yaitu Lab Static Default Route
Tujuan
Setting static default route
Konsep Dasar
Static default route adalah static route dengan network address destination 0.0.0.0 dan subnet
mask 0.0.0.0. Dikenal juga sebagai “quad zero” route. Static default route melakukan identifikasi
gateway yang akan digunakan oleh router untuk mengirimkan semua paket IP untuk network
destination yang tidak diketahui di routing table, sehingga akan diforward ke route 0.0.0.0/0.
Untuk konfigurasi static default route dapat menggunakan next-hop ip address atau exit-interface.
Router(config)# ip route 0.0.0.0 0.0.0.0 {ip-address or exit-intf}
Static default route:
Default route dapat digunakan ketika network destination tidak diketahui (Internet)
Default route dapat digunakan ketika hanya ada satu jalur keluar untuk semua network
destination
Dapat mengurangi ukuran routing table
Jika router tidak menemukan entry network destination di routing table, maka router akan
memforward paket ke default route
Menjadi route pilihan terakhir di routing table
Konfigurasi
Login console ke R1 atau R2 untuk mempraktikkan Lab-5 Static Default Route.
Setelah mengerjakan Lab 4, gunakan kembali topologi Lab 4 beserta solutionnya untuk
mempraktikkan Lab 5.
Untuk mensimulasikan default route di R1, hapus terlebih dahulu static route di R1 sedangkan R2
masih seperti semula. Setelah disetting static default route di R1 kemudian tes Ping dari Laptop1
ke Laptop2. Sebaliknya, untuk mencoba default route di R2, hapus static route di R2 dan setting
ulang static route di R1 seperti di Lab 4. Kemudian tes Ping dari Laptop2 ke Laptop1.
Hapus static route di R1
R1(config)#
R1(config)#no ip route 192.168.2.0 255.255.255.0 12.12.12.2
R1(config)#no ip route 172.16.3.0 255.255.255.0 12.12.12.2
R1(config)#no ip route 172.16.4.0 255.255.255.0 12.12.12.2
R1(config)#
Setting static default route di R1
Command untuk mensetting static default route menggunakan next-hop ip address.
R1(config)#
R1(config)# ip route 0.0.0.0 0.0.0.0 12.12.12.2
R1(config)#
Command untuk mensetting static default route menggunakan exit-interface
R1(config)#
R1(config)# ip route 0.0.0.0 0.0.0.0 fa1/0
Pilih salah satu command diatas apakah ingin menggunakan next-hop ip address atau exitinterface.

di R1 static default route dengan kode S*. Perhatikan perbedaannya ada * di R1.
Sekarang kita akan mencoba static default route di R2, berarti di R1 harus disetting static route
terlebih dahulu dan hapus konfigurasi static default route yang ada. Cek kembali solution Lab 4.
Hapus static default route di R1
Command untuk menghapus settingan static default route menggunakan next-hop ip address.
R1(config)#
R1(config)#no ip route 0.0.0.0 0.0.0.0 12.12.12.2
R1(config)#
Command untuk menghapus settingan static default route menggunakan exit-interface
R1(config)#
R1(config)#no ip route 0.0.0.0 0.0.0.0 fa1/0
R1(config)#
Setting static route di R1
R1(config)#
R1(config)#ip route 192.168.2.0 255.255.255.0 12.12.12.2
R1(config)#ip route 172.16.3.0 255.255.255.0 12.12.12.2
R1(config)#ip route 172.16.4.0 255.255.255.0 12.12.12.2
R1(config)#
Sebelum melanjutkan langkah berikutnya, hapus terlebih dahulu static route di R2. Dan tampilkan
hasilnya menggunakan show ip route, pastikan hanya C saja yang masih ada di routing table R2.
Setting static default route di R2
Command untuk mensetting static default route menggunakan next-hop ip address.
R2(config)#
R2(config)# ip route 0.0.0.0 0.0.0.0 12.12.12.1
Command untuk mensetting static default route menggunakan exit-interface
R2(config)#
R2(config)# ip route 0.0.0.0 0.0.0.0 fa1/0
R2(config)#
Pilih salah satu command diatas apakah ingin menggunakan next-hop ip address atau exitinterface.

Tanda S* menandakan static default route. Setiap network destination yang tidak diketahui
dirouting table akan diforward ke 12.12.12.1. Lihat juga pada bagian Gateway of last resort yang
menyatakan bahwa untuk menuju network 0.0.0.0 gunakan gatewaynya 12.12.12.1.
