Parameter

password: Specifies the password to be configured.

Description
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.
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.
Related command: area-authentication-mode and isis authentication-mode.
Example
# When you need to authenticate the layer 2 routing packets, you can select the simple
mode, and the password is "huawei".
[3Com ] isis
[3Com -isis] domain-authentication-mode simple huawei
