IS-IS configuration commands
The term "router" in this chapter refers to both routers and Layer 3 switches.
HPE FlexNetwork 3600 v2 SI Switch Series does not support IS-IS.

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.
