Konfigurasi Routing OSPF Single Area Dan Multi Area // BLC Telkom - Bestpath-Network
PENDAHULUAN
Pengertian
OSPF (Open Shortest Path First) Adalah Salah satu dari beberapa cara melakukan Routing secara Dinamis (Otomatis), OSPF ini mampu untuk menjaga, megatur dan mendistribusikan informasi antar network mengikuti setiap perubahan pada jaringan secara dinamis (otomatis).
Latar Belakang Masalah
Karena belum paham dan mengerti seperti apa konfigurasi OSPF itu
MAKSUD DAN TUJUAN
Maksud
Agar bisa melakukan konfigurasi OSPF
Tujuan
Bisa paham, mengerti konsep OSPF dengan melakukan simulasi/konfigurasi di Packet tracer
BATASAN DAN RUANG LINGKUP PEKERJAAN
Melakukan konfigurasi OSPF Single Area & Multi Area
TARGET DAN HASIL YANG DIHARAPKAN
Bisa paham, mengerti dan bisa mengimplementasikan OSPF
METODE PELAKSANAAN
- Penjelasan
- Peaktek konfigurasi
ALAT DAN BAHAN
- Laptop
- Koneksi Internet
- PKA OSPF
TARGET WAKTU
4 Jam
TAHAPAN PELAKSANAAN
- Di jelaskan mengenai topologi OSPF tersebut
- Melakukan konfigurasi pada topologi
sekarang kita mulai melakukan konfigurasi OSPF Single Area

NT : Apabila masih tidak bisa Routing nya biasanya Packet tracer nya nge-bug
[Solved] Caranya dengan melakukan Reload pada perangkat tersebut
Contoh :
Router#sh ip route
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
* - candidate default, U - per-user static route, o - ODR
P - periodic downloaded static route
Gateway of last resort is not set
20.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C 20.20.20.0/24 is directly connected, GigabitEthernet0/0/0
L 20.20.20.2/32 is directly connected, GigabitEthernet0/0/0

Router#reload

Dan berhasil :)
TEMUAN PERMASALAHAN DAN CARA PENYELESAIAN MASALAHNYA
Permaslahan : Perangkat tidak ada routing OSPF nya padahal sudah di beri
Solusi : Perangkat nya di Reload
KESIMPULAN YANG DIDAPAT
Untuk melakukan Routing OSPF harus teliti ketika men-input IP, Subnet dan Area nya
