Configuring OSPFv3 to Filter Received Routes

By configuring filtering conditions for routing information, you can allow only the routes that pass the filtering to be received or advertised.

After receiving LSAs, OSPFv3 determines whether to add the calculated routes to the local routing table according to the filtering policy.

Access the system view.
system-view
Access the OSPFv3 process view.
ospfv3 [ process-id ]
Filter the received routing information.
filter-policy { acl6-number | ipv6-prefix ipv6-prefix-name } import

The filter-policy import command is only executed to filter the routes calculated by OSPFv3. The routes that are filtered out are not added into the local routing table, and cannot guide packet forwarding.
