470 CHAPTER 26: INTEGRATED IS-IS CONFIGURATION COMMANDS
Use the undo domain-authentication-mode command to configure IS-IS not to
authenticate the said packets.
By default, the system will not authenticate the received level-2 routing packets,
and there is no password. By using this command, all the level-2 routing packets,
whose domain authentication passwords do not consist with the one set via this
command will not be received. 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 command: area-authentication-mode, isis authentication-mode.
Example
# When you need to authenticate the level-2 routing packets, you can select the
simple mode, and the password is "3com".
[SW8800] isis
[3Com-isis] domain-authentication-mode simple 3com

Parameter
acl-number: Specifies the number of the access control list, ranging from 2000 to
3999.
routing-protocol: Specifies the protocols that distribute routing information,
including direct, static, rip, bgp, ospf, ospf-nssa and ospf-ase. 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.
Example
# Use ACL 2000 to filter all the routes advertised by IS-IS.
[3Com-isis] filter-policy 2000 export
