Konfigurasi Juniper Routing Dynamic (OSPF Backbone area)

Assalamu'alaikum Wr Wb.

Pada kali ini kita akan melanjutkan lab sebelumnya, pembahasan kali ini adalah masih di dalam tema routing lebih tepatnya dynamic routing, pada blog kali ini kita akan membahas tentang OSPF (Open Shortest Path Firs) untuk area karna pembahasan awal kita memakai area backbone atau area 0.

Oke untuk topologi seperti dibawah.

Konfigurasi IP Addressing

Konfigurasi Client/PC

    PC1>ip 192.168.1.2/24 192.168.1.1

PC2

    PC2>ip 192.168.2.2/24 192.168.2.1

PC3

    PC3>ip 192.168.3.2/24 192.168.3.1

Untuk konfigurasi OSPF hanya seperti itu saja dengan mengadvertise interface dan setting area

Oke kita lanjut ke verifikasi labnya cekidot....

R1

R2

R3

Terlihat untuk tabel routing sudah lengkap

Verifikasi Ping antar Loopback

Cek OSPF Neighbor

Cek OSPF Database

Oke sekarang kita cek Ping antar PC

PC1

Sampai sini pembahasan kita tentang routing OSPF dari setting IP, setting area dan advertise interface. Semoga bermanfaat :)
