 Note:
z The filter-policy export command only takes effect to the routes imported by the
import-route command. If you configure the switch with only the filter-policy
export command, but without configuring the import-route command to import
other external routes, then the filter-policy export command does not take effect.
z If the filter-policy export command does not specify which route to be filtered, then
the all the routes imported by the import-route command will be filtered.
For the related commands, see filter-policy import.

Description
Using filter-policy import command, you can configure to filter the routes received by
IS-IS. Using undo filter-policy import command, you can configure not to filter the
received routes.
By default, IS-IS does not filter the received routing information.

accepted. You can configure the filter-policy to specify the filter conditions so as to
accept the desired routing information only.
