1296 CHAPTER 84: IPV6 OSPFV3 CONFIGURATION COMMANDS
Use the undo filter-policy export command to remove the configuration.
If no protocol is specified, all redistributed routes will be filtered.
By default, IPv6 OSPFv3 does not filter redistributed routes.
n
Using the filter-policy export command filters only routes redistributed by the
import-route command. If the import-route command is not configured to
redistribute routes from other protocols and other OSPFv3 processes, use of the
filter-policy export command does not take effect.
Examples # Filter all redistributed routes using IPv6 ACL 2001.
<Sysname> system-view
[Sysname] acl ipv6 number 2001
[Sysname-acl6-basic-2000] rule permit source 2002:1:: 64
[Sysname-acl6-basic-2000] quit
[Sysname] ospfv3
[Sysname-ospfv3-1] filter-policy 2001 export

Use the
