5.2.13 Setting IS-IS Authentication
I. Setting Interface Authentication
The authentication password set on the interface is mainly used in the Hello packet so
as to confirm the validity and correctness of its peers. The authentication passwords at
the same level of all the interfaces of a network should be identical.
Perform the following configurations in Interface view.

By default, the interface is not configured with any authentication password or performs
authentication. If the level is not specified, it defaults to setting the authentication
password of Level-1. If no ip or osi is set, the default settings is osi.
II. Setting IS-IS Area or IS-IS Routing Domain Authentication Password
Users can configure the IS-IS area or the IS-IS routing domain with authentication
password.
If area authentication is needed, the area authentication password will be encapsulated
into the level-1 LSP, CSNP and PSNP packets, in the specified mode. If other routers in
the same area also have started the area authentication, the authentication modes and
passwords of them must be identical to the old ones, so that they can work normally.
Similarly, for domain authentication, the password will also be encapsulated into the
level-2 LSP, CSNP and PSNP packets in the specified mode. If the routers in the
backbone layer (level-2) also need domain authentication, the authentication mode and
password must be identical to the old ones.
Please note, the passwords for authentication of the routers on the same network
segment must be identical.
Perform the following configurations in IS-IS view.
