isis circuit-level
ROTOCOL
level-2: Configures authentication password for Level-2.
ip: Specifies the IP authentication password.
osi: Specifies the OSI authentication password.
The configuration of ip or osi authentication password is independent of the real
network environment.
Description
Using the isis authentication-mode command, you can configure the IS-IS to
authenticate the hello messages of the corresponding level, in the specified mode
and with the specified password on the IS-IS interface. Using the undo isis
authentication-mode command, you can cancel the authentication and delete the
password at the same time.
By default, the password is not set and no authentication is executed.
If the password is set, but no parameter is specified, the default settings are
Level-1, simple and osi.
For the related commands, see area-authentication-mode and
domain-authentication-mode.
Example
Set the authentication password "tangshi" in simple text for the Level-1
neighboring relationship onInterface serial1/0/0.
[3Com] interface serial1/0/0
[3Com-Serial1/0/0] isis authentication-mode simple tangshi level-1

level-1: Configures only Level-1 adjacency instead of Level-2 one on the current
interface.
level-1-2: Configures both Level-1 and Level-2 adjacency on the current
interface.
level-2: Configures only Level-2 adjacency on the current interface.
Description
Using the isis circuit-level command, you can configure the link adjacency
relationship. Using the undo isis circuit-level command, you can restore the default
setting.
By default, you can configure both Level-1 and Level-2 adjacency on the interface.
If the local router is a Level-1-2 router and it is required to establish a correlation
with the peer router on a certain level (Level-1 or Level-2), this command can
specify the interface to send and receive hello messages of this level. Certainly,
