Step Command

Remarks

3.

Configure a priority for

OSPFv3.

preference [ ase ] [ route-policy
route-policy-name ] preference

Optional.
By default, the priority of OSPFv3 internal

routes is 10, and priority of OSPFv3
external routes is 150.

Configuring OSPFv3 route redistribution

To configure OSPFv3 route redistribution:

Step 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.
The default setting is
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.

NOTE:

Executing the import-route or default-route-advertise command on a router makes it become an
ASBR.

You can only inject and advertise a default route using the default-route-advertise command.

Since OSPFv3 is a link state routing protocol, it cannot directly filter LSAs to be advertised. You must filter
redistributed routes first. Only routes that are not filtered out can be advertised in LSAs into the routing

domain.

Using 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.

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.
