Parameter
simple: Transmits the password in simple text.
md5: Transmits the password encrypted with MD5.
password: Specifies the password to be configured, in the range of 1~24 bits.
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
Use the area-authentication-mode command to configure IS-IS to authenticate the
received Level-1 routing information packets (LSP, CSNP and PSNP), according to the
pre-defined mode and password.
Use the undo area-authentication-mode command to configure IS-IS not to
authenticate the said packets.
In default configuration, the system will not authenticate the received Level-1 routing
information packets, and there is no password. By using this command, you can clear
all the Level-1 routing packets, whose area authentication passwords are not
consistent with the one set via this command. At the same time, this command will let
IS-IS insert the area authentication password into all the Level-1 routing packets sent
by this node, in a certain mode.
