These are the three different types of authentication supported by OSPF.
- Null Authentication—This is also called Type 0 and it means no authentication information is included in the packet header. It is the default.
- Plain Text Authentication—This is also called Type 1 and it uses simple clear-text passwords.
- MD5 Authentication—This is also called Type 2 and it uses MD5 cryptographic passwords.
Plan Text Authentication
interface eth0 ip address 192.16.64.2/24 ip ospf authentication-key AUTH_KEY ip ospf authentication-key $AP7i1 !--- The Key value is set as "$AP7i1". !--- It is the password that is sent across the network.
router ospf 10 log-adjacency-changes network 70.0.0.0/8 area 0 network 192.16.64.0/24 area 0 area 0 authentication
MD5 Authentication
interface eth0 ip address 192.16.64.2/24 ip ospf message-digest-key KEYID md5 KEY ip ospf message-digest-key 1 md5 $AP7i1 !--- Message digest key with ID "1" and !--- Key value (password) is set as "$AP7i1".
router ospf 10 network 192.16.64.0/24 area 0 area 0 authentication message-digest !--- MD5 authentication is enabled for !--- all interfaces in Area 0.
