Use the
isis authentication-mode
command to set the IS-IS authentication mode and password for
an interface.
Use the
undo isis authentication-mode
command to restore the 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.
Note that:

specified at both ends.
z
If you configure a password without specifying a level, the password applies to both Level-1 and
Level-2.
z

ip
nor
osi
is specified, the OSI related fields in LSPs are checked.
z
The
level-1
and
level-2
keywords are available only on Layer 3 Ethernet interfaces and VLAN
interfaces after IS-IS is enabled on the interfaces with the
isis enable
command.
