Common Configuration Commands” on page 1187 for routing policy 
information.

protocol: Filter routes redistributed from the specified routing protocol before 
advertisement. The routing protocol can be bgp4+, direct, isisv6, ospfv3, ripng 
or static at present. If no protocol is specified, routes redistributed from all 
protocols are filtered before advertisement.

process-id: Process ID of the routing protocol, ranging from 1 to 65535. This 
argument is available when the protocol is isisv6, ospfv3 or ripng.

Use the ipv6 filter-policy export command to configure IPv6 IS-IS to filter 
redistributed routes before advertisement.

Use the undo ipv6 filter-policy export command to disable the filtering.

The filtering is disabled by default.

In some cases, only routes satisfying certain conditions will be advertised. You can 
configure the filtering conditions using the ipv6 filter-policy command.

You can use the ipv6 filter-policy export command, which filters redistributed 
routes only when they are advertised to other routers, in combination with the 
ipv6 import-route command.

■

If no protocol is specified, routes redistributed from all protocols are filtered 
before advertisement.

■

If a protocol is specified, only routes redistributed from the protocol are filtered 
before advertisement.

# Reference the ACL6 2006 to filter all the redistributed routes before 
advertisement.
