Objective
Mempelajari berbagai macam tipe LSA yang ada pada OSPF

Metode Lab
Konfigurasikan OSPF sesuai topologi diatas
Pada router RM-R1 dibuat beberapa ip loopback yang kemudian diadvertise ke EIGRP dan selanjutnya diredistribute ke OSPF

Verifikasi
Jalankan show ip ospf database untuk pengecekan masing-masing tipe LSA nya

Pada Lab kali ini saya akan membuat beberapa area berbeda serta route lain selain ospf yakni EIGRP. Tujuanya untuk dapat mengetahui LSA tipe berapa saja yang ada dan digunakan oleh OSPF
