simple
: Specifies the simple authentication mode.
cipher
: Sets a ciphertext password. If this keyword is not specified, you set a plaintext password.
password
: Sets the password. This argument is case sensitive. It must be a plaintext string of 1 to 16
characters, or a ciphertext string of 33 to 53 characters.
level-1
: Configures the password for Level-1.
level-2
: Configures the password for Level-2.
ip
: Checks IP related fields in LSPs and SNPs.
osi
: Checks OSI related fields in LSPs and SNPs.
NOTE:
•
This command is not available in loopback interface view.
•
Whether a password should use
ip
or
osi
is not affected by the actual network environment.
Description
Use
isis authentication-mode
to set the IS-IS authentication mode and password for an interface.
Use
undo isis authentication-mode
to restore the default.
No neighbor relationship authentication is configured by default.
The password in the specified mode is inserted into all outgoing hello packets and is used for
authenticating the incoming hello packets. Only the authentication succeeds can the neighbor
relationship be formed.
For two routers to become neighbors, the same authentication mode and password must be
specified at both ends.
The authentication password, set in either plain text or cipher text, is saved to the configuration file in
cipher text.
If you configure a password without specifying a level, the password applies to both Level-1 and
Level-2.
If neither
ip
nor
osi
is specified, the OSI related fields in LSPs are checked.
The
level-1
and
level-2
keywords are configurable on an interface that has had IS-IS enabled with
the
isis enable
command.
