OSPF Lab 3 : Standard Area

By :

 LAB 3


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

* Perhatikan perbedaan Route Kode dilihat R3 di atas. 
• Route 2.2.2.2 , itu muncul sebagai Tipe Route ‘O’ (Normal OSPF Route) 
• Route 100.100.100.1 , ia muncul sebagai Tipe Route ‘OIA’ (OSPF Inter-Area Route) 
• Route 100.100.100.4, ia muncul sebagai Tipe Route ‘0E2’ (OSPF External Route Type 2
