Reset konfigurasi OpenWRT menggunakan teknik BIRD: dari OpenWRT
R1:
ifconfig eth1 10.10.1.1 netmask 255.255.255.252 ifconfig eth2 10.10.1.5 netmask 255.255.255.252 ifconfig eth3 192.168.122.100 netmask 255.255.255.0 ifconfig eth3 192.168.122.101 netmask 255.255.255.0 ifconfig eth3 192.168.122.102 netmask 255.255.255.0
Router2:
ifconfig eth1 10.10.1.6 netmask 255.255.255.252 ifconfig eth2 10.10.1.9 netmask 255.255.255.252 ifconfig eth3 172.16.1.1 netmask 255.255.0.0
Router3:
ifconfig eth1 10.10.1.2 netmask 255.255.255.252 ifconfig eth2 10.10.1.10 netmask 255.255.255.252 ifconfig eth3 192.168.1.1 netmask 255.255.255.0
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.
