Lab 5. OSPF Totally Stub Area

• Lebih sadis dari Stub Area, karena kini benar – benar totally stub.

• Bukan hanya Exernal Route saja, bahkan internal route dari OSPF area lain juga tidak dimasukkan            dalam routing table.

• Konfigurasi hanya dilakukan pada router ABR saja, tidak di semua router dalam stub area.

• Router R2 merupakan ABR (Area Border Router) yang menghubungkan area 0 dan stub area 1.

R2:

R2(config)#router ospf 2

R2(config-router)#no area 1 stub

R2(config-router)#area 1 stub no-summary

R2(config-router)#exit

R3:

R3(config)#do sh ip route ospf

O*IA 0.0.0.0/0 [110/2] via 23.23.23.2, 00:36:51, GigabitEthernet1/0

    2.0.0.0/32 is subnetted, 1 subnets

O 2.2.2.2 [110/2] via 23.23.23.2, 00:36:51, GigabitEthernet1/0

O IA 100.100.100.1 [110/3] via 23.23.23.2, 00:16:30, GigabitEthernet1/0

O IA 100.100.100.2 [110/3] via 23.23.23.2, 00:16:30, GigabitEthernet1/0

O IA 100.100.100.3 [110/3] via 23.23.23.2, 00:16:30, GigabitEthernet1/0

Maka pada OSPF Tottaly Stub Area tidak lagi terdapat dalam routing tablenya.

R3(config)#do sh ip ospf database
