4. Run the following commands to configure the authentication mode of the OSPF area
as required:
– Run:
authentication-mode simple [ plain plain-text | [ cipher ] cipher-
text ]
The simple authentication is configured for the OSPF area.
– Run:
authentication-mode { md5 | hmac-md5 | hmac-sha256 } [ key-id { plain
plain-text | [ cipher ] cipher-text } ]
The MD5 authentication is configured for the OSPF area.
OSPF supports packet authentication. Only the OSPF packets passing the
authentication can be received; otherwise, the neighbor relationship cannot be
established normally.
All the routers in an area must agree on the same area authentication mode and
password. For example, the authentication mode of all routers in area 0 is simple
authentication, and the password is abc.
– Run:
authentication-mode keychain keychain-name
The Keychain authentication is configured for the OSPF area.
NOTE
Before using the Keychain authentication, you must run the keychain command to create
a keychain. Then, run the key-id, key-string, and algorithm commands to configure a key
ID, a password, and an authentication algorithm for this keychain. Otherwise, the OSPF
authentication will fail.
Configuring the Interface Authentication Mode
1. Run:
system-view
The system view is displayed.
2. Run:
interface interface-type interface-number
The interface view is displayed.
3. Run the following commands to configure the interface authentication mode as
required:
– Run:
ospf authentication-mode simple [ plain plain-text | [ cipher ] cipher-
text ]
The simple authentication is configured for the OSPF interface.
– Run:
ospf authentication-mode { md5 | hmac-md5 | hmac-sha256 } [ key-id
{ plain plain-text | [ cipher ] cipher-text } ]
The MD5 authentication is configured for the OSPF interface.
– Run:
ospf authentication-mode null
The non-authentication mode is configured for the OSPF interface.
