Command Reference
area-authentication-mode
Purpose 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.
Syntax area-authentication-mode { simple | md5 } password [ ip | osi ]
undo area-authentication-mode { simple | md5 } [ ip | osi ]
Parameters 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.
Default 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.
Example Set the area authentication password as "hello" and the authentication type as
simple.
[3Com ] isis
[3Com -isis] area-authentication-mode simple hello
