Konfigurasi
Router1:
enable configure terminal interface ethernet1/1 ip address 10.10.1.1 255.255.255.252 ip ospf message-digest-key 1 md5 $AP7i1 no shutdown exit interface ethernet1/2 ip address 10.10.1.5 255.255.255.252 ip ospf message-digest-key 1 md5 $AP7i1 no shutdown exit ! ! NAT GNS3 gw 192.168.122.1 interface ethernet1/3 ip address 192.168.122.100 255.255.255.0 ip address 192.168.122.101 255.255.255.0 secondary ip address 192.168.122.102 255.255.255.0 secondary no shutdown ip route 0.0.0.0 0.0.0.0 192.168.122.1 end
Router2:
enable configure terminal interface ethernet1/1 ip address 10.10.1.6 255.255.255.252 ip ospf message-digest-key 1 md5 $AP7i1 no shutdown exit interface ethernet1/2 ip address 10.10.1.9 255.255.255.252 ip ospf message-digest-key 1 md5 $AP7i1 no shutdown exit interface ethernet1/3 ip address 172.16.1.1 255.255.0.0 no shutdown end
Router3:
enable configure terminal interface ethernet1/1 ip address 10.10.1.2 255.255.255.252 ip ospf message-digest-key 1 md5 $AP7i1 no shutdown exit interface ethernet1/2 ip address 10.10.1.10 255.255.255.252 ip ospf message-digest-key 1 md5 $AP7i1 no shutdown exit interface ethernet1/3 ip address 192.168.1.1 255.255.255.0 no shutdown end
Ada tiga (3) elemen dasar konfigurasi OSPF:
- Enable OSPF instance
- OSPF area configuration
- OSPF network configuration
Catatan: Ingat bahwa backbone area-id adalah 0.0.0.0.
R1
enable configure terminal ! ! area 0 = backbone router ospf 1 network 10.10.1.0 0.0.0.3 area 0.0.0.0 network 10.10.1.4 0.0.0.3 area 0.0.0.0 area 0.0.0.0 authentication message-digest end
R2
enable configure terminal ! ! area 0 = backbone router ospf 2 network 10.10.1.4 0.0.0.3 area 0.0.0.0 network 10.10.1.8 0.0.0.3 area 0.0.0.0 network 172.16.0.0 0.0.255.255 area 0.0.0.0 area 0.0.0.0 authentication message-digest end
R3
enable configure terminal ! ! area 0 = backbone router ospf 3 network 10.10.1.0 0.0.0.3 area 0.0.0.0 network 10.10.1.8 0.0.0.3 area 0.0.0.0 network 192.168.1.0 0.0.0.255 area 0.0.0.0 area 0.0.0.0 authentication message-digest end
