Chapter 4 IS-IS Configuration Commands
4-2
Note:
Whether a password should use
ip
or
osi
is not affected by the actual network
environment.
Description
Use the
area-authentication-mode
command to specify the area authentication mode
and a password. The password in the specified mode is inserted into all outgoing
Level-1 packets (LSP, CSNP and PSNP) and is used for authenticating the incoming
Level-1 packets.
Use the
undo area-authentication-mode
command to restore the default.
No area authentication mode is specified by default, that is, the system will neither
authenticate incoming Level-1 packets nor set password for outgoing Level-1 packets.
With area authentication mode configured, the system will discard incoming routes
from untrusted routers.
