3-10
 Note:
z Using the import-route command on a router makes the router become an ASBR.
z Since OSPFv3 is a link state based routing protocol, it cannot directly filter LSAs to
be advertised. Therefore, you need to configure filtering redistributed routes before
advertising routes that are not filtered in LSAs into the routing domain.
z Use of the filter-policy export command takes effect only on the local router.
However, if the import-route command is not configured, executing the
filter-policy export command does not take effect.
3.6 Tuning and Optimizing an OSPFv3 Network
This section describes configurations of OSPFv3 timers, interface DR priority, MTU
check ignorance for DD packets, disabling interfaces from sending OSPFv3 packets.
OSPFv3 timers:
z Packet timer: Specified to adjust topology convergence speed and network load
z LSA delay timer: Specified especially for low speed links
z SPF timer: Specified to protect networks from being over consumed due to
frequent network changes.
For a broadcast network, you can configure DR priorities for interfaces to affect
DR/BDR election.
By disabling an interface from sending OSPFv3 packets, you can make other routers
on the network obtain no information from the interface.
