Configuring OSPFv3 route control

Configuration prerequisites

Before you configure OSPFv3 route control, perform the following tasks:
•
Configure IPv6 addresses for interfaces to ensure IPv6 connectivity between neighboring
nodes.
•
Enable OSPFv3.

Configuring OSPFv3 route summarization

Route summarization enables an ABR or ASBR to summarize contiguous networks into a single
network and advertise it to other areas.
Configuring route summarization on an ABR
If contiguous network segments exist in an area, you can summarize them into one network segment
on the ABR. The ABR will advertise only the summary route. Any LSA on the specified network
segment will not be advertised, reducing the LSDB size in other areas.
To configure route summarization on an ABR:
Step
1. Enter system view.
2. Enter OSPFv3 view.
3. Enter
view.
4. Configure
summarization on the
ABR.
Configuring route summarization on an ASBR
Perform this task to enable an ASBR to summarize external routes within the specified address
range into a single route.
An ASBR can summarize routes in the following LSAs:
•
Type-5 LSAs.
•
Type-7 LSAs in an NSSA area.
•
Type-5 LSAs translated by the ASBR (also an ABR) from Type-7 LSAs in an NSSA area.
If the ASBR (ABR) is not a translator, it cannot summarize routes in Type-5 LSAs translated
from Type-7 LSAs.
To configure route summarization on an ASBR:
Step
1. Enter system view.
2. Enter OSPFv3 view.
