Command Reference
domain-authentication-mode
Purpose Use the domain-authentication-mode command to configure IS-IS route area
to authenticate the received Level-2 routing packets (LSP, CSNP, PSNP), according to
the pre-defined mode and password.
Use the undo domain-authentication-mode command to configure IS-IS not
to authenticate the said packets.
Syntax domain-authentication-mode { simple | md5 } password [ ip | osi ]
undo domain-authentication-mode { simple | md5 } [ ip | osi ]
Parameters simple
Transmits the password in simple text.
md5
Transmits the password in MD5 encryption.
password
Specifies the password to be configured.
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-2 routing
packets, and there is no password. By using this command, you can discard all the
Layer 2 routing packets, whose area authentication passwords do not consist 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 Layer 2 routing packets sent by this node, in
a certain mode.
Example When you need to authenticate the layer 2 routing packets, you can select the simple
mode, and the password is "3Com".
[3Com ] isis
[3Com -isis] domain-authentication-mode simple 3Com
