Tujuan Lab
Menhubungkan semua Router menggunakan OSPF, BGP dan RIP. Dalam OSPF terdapat area Stub dan NSSA yang tidak akan menerima informasi dari Routing Protocol lainnya (RIP, BGP), untuk komunikasi antar Routing protocol maka kita harus melakukan redistribute.
Area Backbone
Area backbone ini merupakan area pusat dan transit seluruh informasi yang didapatkan oleh OSPF, dalam area ini terdapat 4 Router yaitu R1, R2, R10, dan R11IP Address
Kita konfigurasi IP Address seluruh interface RouterR1
/ip address add address=12.12.12.1/24 interface=ether1 network=12.12.12.0 add address=17.17.17.1/24 interface=ether2 network=17.17.17.0 add address=110.110.110.1/24 interface=ether3 network=110.110.110.0

Setiap Router pada area ini tidak akan menerima informasi yang berasal dari Routing protocol lainnya yaitu BGP dan RIP karena area ini merupakan area Stub pada OSPF.IP Address

Area 4 NSSA
Pada area ini sama seperti area stub yaitu area yang tidak akan menerima informasi dari Routing Protocol lain selain OSPF, akan tetapi pada area NSSA masih memiliki informasi dari Routing protocol lain dia sendiri dan mendistribusikannya pada setiap area OSPF lainnya, itu sebabnya pada area ini saya juga menggunakan BGP sebagai contohnya.IP Addresss

R7
Pada Router ini juga menggunakan OSPF maka kita konfigurasi redistribute pada Router ini, karena pada Router ini memiliki default route (hasil area nssa) maka kita set default-originate=always/routing bgp instance
set default disabled=yes
add as=7 name=lab-bgp redistribute-connected=yes redistribute-ospf=yes \

/routing rip set redistribute-ospf=yes /routing rip network add network=13.14.13.0/24
R15
/routing rip set redistribute-ospf=yes /routing rip network add network=14.15.14.0/24
RIP pada R14
Router ini berada diantara dua area OSPF yang menjalankan Routing Protocol RIPR14
/ip address add address=13.14.13.14/24 interface=ether1 network=13.14.13.0 add address=14.15.14.14/24 interface=ether2 network=14.15.14.0 /routing rip network add network=13.14.13.0/24 add network=14.15.14.0/24

Setelah semua konfigurasi selesai dilakukan sekarang kita cek apakah konfigurasi sudah benar.Routing Table Backbone Area

Terlihat jika pada Stub area informasi yang didapatkan lebih sedikit dan digantikan dengan default route.
