168 CHAPTER 5: USING ROUTING PROTOCOL COMMANDS
Description
Use the domain-authentication-mode command to configure IS-IS 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 clear
all the level-2 routing packets, whose domain authentication passwords do not
consist with the one set via this command. At the same time, this command will
let IS-IS insert the domain authentication password into all the level-2 routing
packets sent by this node, in a certain mode.
Related commands: area-authentication-mode, isis authentication-mode.
Example
To authenticate the level-2 routing packets, select the simple mode, and the
password is "3Com".
[SW7700]isis
[SW7700-isis]domain-authentication-mode simple 3Com

View
IS-IS view
Parameter
acl-number: Specify the number of the access control list, ranging 1 to 199.
protocol: Specify the protocols that distribute routing information, including
direct, static, rip, bgp, ospf, and ospf-ase etc. If it does not specify any protocol,
the distributed routes of all the protocols will be filtered.
Description
Use the filter-policy export command to configure to filter the routes
distributed by IS-IS.
Use the undo filter-policy export command to cancel the filtering for the
exporting routes.
By default, IS-IS does not filter any distributed routing information.
In some cases, only the routing information meeting the specified conditions will
be distributed. You can configure the filter-policy to specify the filter conditions so
as to distribute the desired routing information only.
Related command: filter-policy import.
