Jika EIGRP hanya mendukung md5 untuk authentikasinya ospf mendukung 2 mode authentikasi yaitu clear text & md5..
OK kita mulai dengan clear text..

IDN1
 
interface FastEthernet0/0
ip address 12.12.12.1 255.255.255.0
ip ospf authentication
ip ospf authentication-key SECRET
ip ospf 1 area 0
!
interface FastEthernet0/1
ip address 13.13.13.1 255.255.255.0
ip ospf authentication
ip ospf authentication-key SECRET
ip ospf 1 area 0

 
IDN2

interface FastEthernet0/0
ip address 12.12.12.2 255.255.255.0
ip ospf authentication
ip ospf authentication-key SECRET
ip ospf 1 area 0
!
interface FastEthernet0/1
ip address 23.23.23.2 255.255.255.0
ip ospf authentication
ip ospf authentication-key SECRET
ip ospf 1 area 0


IDN3

interface FastEthernet0/0
ip address 13.13.13.3 255.255.255.0
ip ospf authentication
ip ospf authentication-key SECRET
ip ospf 1 area 0
!
interface FastEthernet0/1
ip address 23.23.23.3 255.255.255.0
ip ospf authentication
ip ospf authentication-key SECRET
ip ospf 1 area 0


Yap, lebih simple lagikan authentikasi ospf dibanding EIGRP. Pada OSPF jika kita gunakan command �ip ospf 1 area 0? maka kita tidak perlu membuat proses OSPF�

Ya, terlihat �Simple password authentication enabled� yang berarti authentikasi clear text sudah bekerja..
Next we will create md5 authentication just between IDN1 � IDN2, let�s go..

IDN1
interface FastEthernet0/0
ip ospf authentication message-digest
ip ospf authentication-key SECRET
ip ospf message-digest-key 1 md5 CISCO

IDN2
interface FastEthernet0/0
ip ospf authentication message-digest
ip ospf authentication-key SECRET
ip ospf message-digest-key 1 md5 CISCO

Kita bisa langsung konfig authentikasinya tanpa menghapus authentikasi yang lama�

Ok authentikasi yang lama sudah berganti menjadi md5..
