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.

# When you need to authenticate the level-2 routing packets, you can select the 
simple mode, and the password is "3com".

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.

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.

# Use ACL 2000 to filter all the routes advertised by IS-IS.
