Related command: area-authentication-mode, domain-authentication-mode.
Example
# Set the authentication password “tangshi” in plain text for the Level-1 neighboring
relationship on Interface Vlan-interface 10.
[Quidway] interface Vlan-interface 10
[Quidway-Vlan-interface10] isis authentication-mode simple tangshi level-1
4.1.19 isis circuit-level
Syntax
isis circuit-level [ level-1 | level-1-2 | level-2 ]
undo isis circuit-level
View
Interface view
Parameter
level-1: Configures Level-1, instead of Level-2, adjacency on the current interface only.
level-1-2: Configures Level-1-2 adjacency on the current interface.
level-2: Configures Level-2 adjacency on the current interface only.
Description
Use the isis circuit-level command to have the Level-1-2 router set up link adjacency
with the peer router.
Use the undo isis circuit-level command to restore the default setting of the link
adjacency on the Level-1-2 router.
By default, the value is level-1-2.
This command is only applicable to Level-1-2 routers. 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
packets of this level. Certainly, only one type of Hello packet is sent and received on the
point-to-point link. In this way, excessive processing is avoided, and the bandwidth is
saved.
Related command: is-level.
Example
# When interface Vlan-interface 10 is connected with a non-backbone router in the
same area, you can set this interface as level-1, prohibiting the sending and receiving
of Level-2 Hello packets.
