NOTE:
The level-1 and level-2 keywords are configurable on an interface that has IS-IS enabled with the isis
enable command.
If you configure an authentication mode and a password without specifying a level, the authentication
mode and password apply to both Level-1 and Level-2.
If neither ip nor osi is specified, the OSI related fields in LSPs are checked.
Configuring area authentication
Area authentication enables a router not to install routing information from untrusted routers into the
Level-1 LSDB. The router encapsulates the authentication password in the specified mode into Level-1
packets (LSP, CSNP, PSNP) and check the password in received Level-1 packets.
Routers in a common area must have the same authentication mode and password.
To configure area authentication:

3. Specify the area
authentication mode and
password.
area-authentication-mode { md5 |
simple } password [ ip | osi ]
By default, no area authentication
is configured.
Configuring routing domain authentication
Routing domain authentication prevents untrusted routing information from entering into a routing
domain. A router with the authentication configured encapsulates the password in the specified mode
into Level-2 packets (LSP, CSNP, PSNP) and check the password in received Level-2 packets.
All the routers in the backbone must have the same authentication mode and password.
