• The filter-policy export command filters routes redistributed with the import-route command. If the
import-route command is not configured, executing the filter-policy export command does not take
effect.
To configure OSPFv3 route redistribution:
Ste
p
Command Remarks
1. Enter system view.
system-view N/A
2. Enter OSPFv3 view.
ospfv3 [ process-id ] N/A
3. Specify a default cost for
redistributed routes.
default cost value
Optional.
Defaults to 1.
4. Redistribute routes from
another protocol or
another OSPFv3 process.
import-route protocol [ process-id |
allow-ibgp ] [ cost value |
route-policy route-policy-name |
type type ] *
Not configured by default.
5. Inject a default route.
default-route-advertise [ always |
cost value | type type | route-policy
route-policy-name ] *
Optional.
Not injected by default.
6. Filter redistributed routes.
filter-policy { acl6-number |
ipv6-prefix ipv6-prefix-name }
export [ isisv6 process-id | ospfv3
process-id | ripng process-id |
bgp4+ | direct | static ]
Optional.
Not configured by default.
Support for the filter-policy command
depends on the device model.
Tuning and optimizing OSPFv3 networks
This section describes configurations of OSPFv3 timers, interface DR priority, MTU check ignorance for
DD packets, and disabling interfaces from sending OSPFv3 packets.
The following are OSPFv3 timers:
• Packet timer—Specified to adjust topology convergence speed and network load.
• LSA delay timer—Specified especially for low-speed links.
• SPF timer—Specified to protect networks from being over-loaded due to frequent network changes.
For a broadcast network, you can configure DR priorities for interfaces to affect DR and BDR election.
After an interface is disabled from sending OSPFv3 packets, other routers cannot obtain any information
from the interface.
Configuration prerequisites
Before you tune and optimize OSPFv3 networks, complete the following tasks:
• Enable IPv6 packet forwarding.
• Configure OSPFv3 basic functions.
