OSPF
Ada tiga (3) elemen dasar konfigurasi OSPF:
- Enable OSPF instance
- OSPF area configuration
- OSPF network configuration
instance name=default sudah ada, tidak perlu di tambahkan, tapi kalau perlu menambahkan caranya adalah sebagai berikut Catatan: Ingat bahwa backbone area-id adalah 0.0.0.0.
R1:
# /routing ospf instance add name=default /routing ospf instance set name=default router-id=10.10.1.1 numbers=0 /routing ospf instance enable numbers=0 /routing ospf network add network=10.10.1.0/30 area=backbone /routing ospf network add network=10.10.1.4/30 area=backbone /routing ospf interface add interface=ether1 authentication=md5 authentication-key=AP7i1 authentication-key-id=1 /routing ospf interface add interface=ether2 authentication=md5 authentication-key=AP7i1 authentication-key-id=1
