HPE FlexNetwork 3600 v2 SI Switch Series does not support IS-IS.

area-authentication-mode

Syntax
area-authentication-mode { md5 | simple } [ cipher ] password [ ip | osi ]
undo area-authentication-mode
View
IS-IS view
Default level
2: System level
Parameters
md5: Specifies the MD5 authentication mode.
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.
ip: Checks IP related fields in LSPs.
osi: Checks OSI related fields in LSPs.
NOTE:
Whether a password should use ip or osi is not affected by the actual network environment.
Description
Use area-authentication-mode to specify the area authentication mode and a password.
Use undo area-authentication-mode to restore the default.
No area authentication is configured by default.
The password in the specified mode is inserted into all outgoing Level-1 packets (LSP, CSNP, and
PSNP) and is used for authenticating the incoming Level-1 packets.
With area authentication configured, IS-IS discards incoming routes from untrusted routers.
Routers in a common area must have the same authentication mode and password.
If neither ip nor osi is specified, OSI related fields are checked.
The authentication password, set in either plain text or cipher text, is saved to the configuration file in
cipher text.

Examples
# Configure the area authentication mode as simple, and set the plaintext password to ivg.
