ospf authentication-mode
Syntax
For MD5/HMAC-MD5 authentication:
ospf authentication-mode { hmac-md5 | md5 } key-id [ cipher | plain ] password
undo ospf authentication-mode { hmac-md5 | md5 } key-id
For simple authentication:
ospf authentication-mode simple [ cipher | plain ] password
undo ospf authentication-mode simple

Parameters
hmac-md5: HMAC-MD5 authentication.
md5: MD5 authentication.
simple: Simple authentication.
key-id: Authentication key ID, in the range of 1 to 255.
cipher: Sets a ciphertext password.
plain: Sets a plaintext password.
password: Sets the authentication password. This argument is case sensitive. For simple authentication
mode, it is plaintext string of 1 to 8 characters, or a ciphertext string of 1 to 41 characters. For
MD5/HMAC-MD5 authentication mode, it is a plaintext string of 1 to 16 characters, or a ciphertext
string of 1 to 53 characters.
Description
Use ospf authentication-mode to set the authentication mode and authentication parameters on an
interface.
Use undo ospf authentication-mode to remove specified configuration.
By default, no authentication is available on an interface.
Interfaces attached to the same network segment must have the same authentication password and
mode.
The authentication password, set in either plain text or cipher text, is saved to the configuration file in
cipher text.
If neither cipher nor plain is specified, cipher applies to the MD5/HMAC-MD5 authentication mode and
plain applies to the simple authentication mode, by default.
Related commands: authentication-mode.
Examples
# Configure the network 131.119.0.0/16 in Area 1 to support MD5 authentication, and set the interface
key ID to 15 and plaintext authentication password to abc.
