Required
By default, the network type of an interface
depends on the link layer protocol.
Configuring OSPF route control
This section covers how to control OSPF routing information advertisement and reception, and route
redistribution from other protocols.
Prerequisites
Before configuring this task, you have configured:
• IP addresses for interfaces
• OSPF basic functions
• Corresponding 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 calculation speed of 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 into other areas.
1. Configuring 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 topological changes.
