3. Configure the OSPF network
type for the interface as P2P.

By default, the network type of
an interface depends on the
link layer protocol.
Configuring OSPF route control
This section describes how to control the advertisement and reception of OSPF routing information, as
well as route redistribution from other protocols.
Configuration prerequisites
Before you configure this task, complete the following tasks:
• Configure IP addresses for interfaces.
• Configure OSPF basic functions.
• Configure filters if routing information filtering is needed.
Configuring OSPF route summarization
You can configure route summarization on an ABR or ASBR to summarize routes with the same prefix into
a single route and distribute it to other areas.
Route summarization reduces the traffic of routing information exchanged between areas and the sizes
of routing tables on routers, improving route calculation speed on routers.
For example, in an area are three internal routes 19.1.1.0/24, 19.1.2.0/24, and 19.1.3.0/24. By
configuring route summarization on the ABR, the three routes are summarized into the route 19.1.0.0/16
that is advertised to other areas.
• Configure route summarization on an ABR.
If contiguous network segments are available in the area, you can summarize them into a single
network segment. An ABR generates Type-3 LSAs on a per network segment basis for an attached
non-backbone area.
In this way, the ABR in the area distributes only the summary LSA to reduce the scale of LSDBs on
routers in other areas and the influence of topology changes.
