OSPF - Stub Area

Sebelumnya telah saya jelaskan bahwa Stub Area tidak ada terdapat LSA type 4, 5 beredar. Kita tau bahwa keberadan LSA type 4 dan type 5 menginformasikan bahwa adanya external network. Berikut ilustrasi topologi Stuba aea.

Adapun konfigurasi untuk masing-masing router adalah sebagai berikut
