Konfigurasi OSPF Single Area on Juniper

waktu itu pernah di bahas mengenai OSPF area kan ya, nah sekarng kita belajar konfigurasi single area dulu, setelah itu kita konfigurasi multi area dan external router lainnya.

Parameter :

• R1 bisa ping Loopback R2
• R2 bisa ping Loopback R1

OSPF Single Area - Konfigurasi Interface
 R1
set logical-systems R1 interfaces em0 unit 0 vlan-id 12
set logical-systems R1 interfaces em0 unit 0 family inet address 12.12.12.1/30
set logical-systems R1 interfaces lo0 unit 1 family inet address 1.1.1.1/32

R2
set logical-systems R2 interfaces em1 unit 0 vlan-id 12
set logical-systems R2 interfaces em1 unit 0 family inet address 12.12.12.2/30
set logical-systems R2 interfaces lo0 unit 2 family inet address 2.2.2.2/32







OSPF Single Area - Konfigurasi Routing Protocol
set logical-systems R1 protocols ospf area 0.0.0.0 interface em0.0
set logical-systems R1 protocols ospf area 0.0.0.0 interface lo0.1 passive

set logical-systems R2 protocols ospf area 0.0.0.0 interface em1.0
set logical-systems R2 protocols ospf area 0.0.0.0 interface lo0.2 passive
command "passive" berfungsi untuk mengadvertise address loopback namun tidak menjalankan protocol ospf pada interface tersebut.

untuk memastikan bahwa protocol dynamic routing berjalan dengan baik, maka kita perlu melakukan verifikasi dengan menggunakan command "show route, ospf neighbor, ospf interface, ospf database.

Verifikasi Routing Protocol
R1
root# run show route logical-system R1

inet.0: 5 destinations, 5 routes (5 active, 0 holddown, 0 hidden)
+ = Active Route, - = Last Active, * = Both

                    > via lo0.1
