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:

configure
set protocols ospf area 0 network 10.10.1.0/30
set protocols ospf area 0 network 10.10.1.4/30
set protocols ospf log-adjacency-changes
set protocols ospf parameters router-id 10.10.1.1
show
show protocols
commit
exit
protocol ospf 10.10.1.1 {
   area 0 {
      networks {
         10.10.1.0/30;
         10.10.1.4/30;
      }
      interface <interface pattern> {
         neighbors {
            <ip>;
            <ip> eligible;
         };
      };
   };
}



R2:

configure
set protocols ospf area 0 network 10.10.1.4/30
set protocols ospf area 0 network 10.10.1.8/30
set protocols ospf area 0 network 172.16.0.0/16
set protocols ospf log-adjacency-changes
set protocols ospf parameters router-id 10.10.1.6
show
show protocols
commit
exit


R3:

configure
set protocols ospf area 0 network 10.10.1.0/30
set protocols ospf area 0 network 10.10.1.8/30
set protocols ospf area 0 network 192.168.1.0/24
set protocols ospf log-adjacency-changes
set protocols ospf parameters router-id 10.10.1.2
show
show protocols
commit
exit

Verify

Cek R1, R2, R3

show ip ospf database 
show ip ospf neighbor
show ip ospf route 
show ip route
