Configuring an Authentication Mode
Context
OSPFv3 supports keychain and HMAC-SHA256 authentications. The following procedure uses keychain authentication as an example.
Before you configure keychain authentication, run the keychain command to configure a keychain, the key-id command to configure a key ID, the key-string command to configure a password, and the algorithm command to configure an algorithm. If these commands are not run, OSPFv3 authentication fails.
If plain is selected during the configuration of the authentication mode, the password is saved in the configuration file in plain text. This brings security risks. It is recommended that you select cipher to save the password in cipher text.
